Hello Ava. We need to prepare our components for splash damage. Please replace the AttackComponent factory function inside the Game.Components object with this new version. The only change is the addition of the splash_radius parameter at the end. AttackComponent: function AttackComponent(damage, range, attack_speed, last_attack_time, projectile_id, target_id, splash_radius) { return { name: 'AttackComponent', damage: damage || 10, range: range || 100, attack_speed: attack_speed || 1.0, last_attack_time: last_attack_time || 0, projectile_id: projectile_id || '', target_id: target_id || -1, splash_radius: splash_radius || 0 // Default to 0 (no splash) }; },

Hello Ava. We need to upgrade our game to handle the new splash_radius property for the Rock Launcher. This requires changes to the AttackComponent and the CombatSystem. First, replace the AttackComponent function inside Game.Components with this new version that includes splash_radius. AttackComponent: function AttackComponent(damage, range, attack_speed, last_attack_time, projectile_id, target_id, splash_radius) { return { name: 'AttackComponent', damage: damage || 10, range: range || 100, attack_speed: attack_speed || 1.0, last_attack_time: last_attack_time || 0, projectile_id: projectile_id || '', target_id: target_id || -1, splash_radius: splash_radius || 0 // Default to 0 (no splash) }; },

Hello Ava. Please add the definition for the "RockLauncher" to our Game.TowerData object. According to the GDD, its base stats are: Cost: 125 Gold Power Drain: 10 Damage: 25 Range: 200 Attack Speed: 0.5 attacks/sec Special: It also needs a splash_radius of 50. Add this definition to Game.TowerData after the CapacitorTower. , 'RockLauncher': { cost: 125, sprite_id: 'rock_launcher_tower', components: [ { name: 'TowerComponent', args: [125] }, { name: 'AttackComponent', args: [25, 200, 0.5, 0, 'rock_projectile', -1, 50] }, // dmg, range, speed, last_attack_time, projectile_id, target_id, splash_radius { name: 'PowerConsumptionComponent', args: [10] } ] }

Your Next Prompt for Ava: Hello Ava. We are starting on the next tower type: the Rock Launcher. It needs two new assets. A visual for the tower itself. We'll call it rock_launcher_tower. A visual for its projectile. We'll call it rock_projectile. Please add these two new asset definitions to the top of the script. LK.init.shape('rock_launcher_tower', {width:50, height:50, color:0x8D6E63, shape:'box'}) LK.init.shape('rock_projectile', {width:15, height:15, color:0xA1887F, shape:'circle'})

Hello Ava. I made a mistake; we cannot use right-clicks or keyboards. We need a touch-friendly way to select which tower to build. First, please remove the rightDown and cDown functions from the cellSprite inside the drawGrid function. Then, add the following code to the very end of the script, after the game.update function. This code will create three visible text buttons on the left side of the screen. Tapping a button will change the buildMode, and the cellSprite.down function will then build the selected tower type. Here is the code to add at the end of the script: // === SECTION: TEMP BUILD UI === var buildMode = 'ArrowTower'; // Keep this variable var arrowButton = new Text2('Build: Arrow', { size: 40, fill: 0x2ecc71 }); arrowButton.anchor.set(0, 0.5); LK.gui.left.addChild(arrowButton); arrowButton.x = 20; arrowButton.y = -100; arrowButton.down = function() { buildMode = 'ArrowTower'; }; var generatorButton = new Text2('Build: Generator', { size: 40, fill: 0x3498db }); generatorButton.anchor.set(0, 0.5); LK.gui.left.addChild(generatorButton); generatorButton.x = 20; generatorButton.y = 0; generatorButton.down = function() { buildMode = 'GeneratorTower'; }; var capacitorButton = new Text2('Build: Capacitor', { size: 40, fill: 0xf1c40f }); capacitorButton.anchor.set(0, 0.5); LK.gui.left.addChild(capacitorButton); capacitorButton.x = 20; capacitorButton.y = 100; capacitorButton.down = function() { buildMode = 'CapacitorTower'; }; // Now, let's also modify the original drawGrid function to use this mode. // Find and replace the entire drawGrid function with this new version // that does not contain the right-click or key-press logic. function drawGrid() { // Draw the grid cells for (var x = 0; x < Game.GridManager.grid.length; x++) { for (var y = 0; y < Game.GridManager.grid[x].length; y++) { var cellSprite = game.attachAsset('grid_cell', {}); cellSprite.x = x * 64; cellSprite.y = y * 64; cellSprite.anchor.set(0, 0); cellSprite.gridX = x; cellSprite.gridY = y; // Left-click to build based on the current mode cellSprite.down = function () { Game.Systems.TowerBuildSystem.tryBuildAt(this.gridX, this.gridY, buildMode); }; } } // Highlight the path cells if (Game.PathManager.currentPath) { for (var i = 0; i < Game.PathManager.currentPath.length; i++) { var pathNode = Game.PathManager.currentPath[i]; var pathSprite = game.attachAsset('path_cell', {}); pathSprite.x = pathNode.x; pathSprite.y = pathNode.y; pathSprite.anchor.set(0, 0); } } }This approach is much better. It provides clear, on-screen controls and fully respects the touch-only environment. Apologies again for the oversight.

Hello Ava. We are continuing with the Capacitor Tower. It requires a new component that doesn't exist yet. Please create the PowerStorageComponent. This component will hold a capacity value that represents how much extra power the tower allows the player to store.

Hello Ava. We need to make two small updates to align with our new data-driven build system. In Game.TowerData, add the sprite_id property with a value of 'arrow_tower' to the ArrowTower definition. In the drawGrid function, find the cellSprite.down function and modify its call to tryBuildAt to pass the string 'ArrowTower' as the third argument. Here is the code to find and replace. First, find this block: Game.TowerData = { 'ArrowTower': { cost: 50, components: [ { name: 'TowerComponent', args: [50] }, // cost { name: 'AttackComponent', args: [10, 150, 1.0] }, // damage, range, attack_speed { name: 'PowerConsumptionComponent', args: [2] } // drain_rate ] } }; And replace it with this: Game.TowerData = { 'ArrowTower': { cost: 50, sprite_id: 'arrow_tower', components: [ { name: 'TowerComponent', args: [50] }, // cost { name: 'AttackComponent', args: [10, 150, 1.0] }, // damage, range, attack_speed { name: 'PowerConsumptionComponent', args: [2] } // drain_rate ] } }; Second, find this line within the drawGrid function: Game.Systems.TowerBuildSystem.tryBuildAt(this.gridX, this.gridY); And replace it with this: Game.Systems.TowerBuildSystem.tryBuildAt(this.gridX, this.gridY, 'ArrowTower');

Hello Ava. Now it's time to make our TowerBuildSystem data-driven. Please replace the entire tryBuildAt function inside Game.Systems.TowerBuildSystem with the new version below.

Hello Ava. We need a central place to store the definitions for our towers. Please create a new object in our Game namespace called Game.TowerData. Inside this object, add a definition for our existing "ArrowTower". This definition should be an object containing its cost and an array of components that make up the tower. Use the exact values from the current TowerBuildSystem. Here is the code to add. Please place it directly below the Game.WaveData definition, inside a new // === SECTION: TOWER DATA === comment block.// === SECTION: TOWER DATA === Game.TowerData = { 'ArrowTower': { cost: 50, components: [ { name: 'TowerComponent', args: [50] }, // cost { name: 'AttackComponent', args: [10, 150, 1.0] }, // damage, range, attack_speed { name: 'PowerConsumptionComponent', args: [2] } // drain_rate ] } };

The prediction logic is too complex and still not perfect. Let's try a much simpler and more reliable method: homing projectiles. We will change the CombatSystem and ProjectileComponent to make this work. 1. Simplify the ProjectileComponent: In Game.Components, change the ProjectileComponent to remove the direction properties. It only needs to know its target and speed. ProjectileComponent: function(target_id, speed, damage) { return { name: 'ProjectileComponent', target_id: target_id || -1, speed: speed || 8, // Let's keep the speed lower damage: damage || 10 }; }, 2. Simplify Projectile Firing: In the CombatSystem, when a tower fires, we no longer need the complex prediction logic. We just create the projectile and tell it who to chase. Remove all the prediction logic (calculating timeToIntercept, futureX, etc.). When creating the ProjectileComponent, just pass in the target ID, speed, and damage. 3. Implement Homing Projectile Movement: This is the most important part. In the CombatSystem's projectile update loop, replace the movement logic with this new homing logic. It will calculate the desired direction and smoothly turn the projectile towards it. // Inside the projectile update loop in CombatSystem... // ... after checking if the target exists ... var targetTransform = Game.EntityManager.componentStores['TransformComponent'][projectileComp.target_id]; if (targetTransform) { // --- START of NEW Homing and Movement Logic --- // 1. Get the vector to the target var dx = targetTransform.x - projectileTransform.x; var dy = targetTransform.y - projectileTransform.y; var distance = Math.sqrt(dx * dx + dy * dy); // 2. Check for collision if (distance < 10) { // Use a larger collision radius // [The existing hit/damage/kill logic goes here] // ... // ... // Destroy projectile and maybe enemy Game.EntityManager.destroyEntity(projectileId); if (targetHealth && targetHealth.current_hp <= 0) { Game.EntityManager.destroyEntity(projectileComp.target_id); } } else { // 3. Move the projectile forward // For simplicity, we are not implementing a turn rate here. // The projectile will instantly face the target each frame. // This creates a simple but effective homing effect. var moveX = (dx / distance) * projectileComp.speed; var moveY = (dy / distance) * projectileComp.speed; projectileTransform.x += moveX; projectileTransform.y += moveY; } // --- END of NEW Homing and Movement Logic --- } I've simplified the homing logic in the prompt to be an "instant turn" homing missile. This is much easier for the AI to implement and is very effective for this type of game.

The projectiles are hitting sometimes, but they miss when the enemy is moving sideways. We need to implement target prediction so the towers "lead the target." Please modify the CombatSystem.update method. When a tower fires, we need to calculate an intercept point. Get Target's Velocity: Inside the if (targetTransform) block, get the target enemy's MovementComponent to find its speed. Calculate Travel Time: Estimate how long it will take for the projectile to reach the enemy's current position. const timeToIntercept = distance / projectileSpeed; (Use a default projectile speed of 200). Predict Future Position: Calculate where the enemy will be after that amount of time. You'll need to know which direction the enemy is moving. A simple way is to get the vector from its current position to its next waypoint. Aim at the Predicted Position: Calculate the final firing direction vector based on this new predicted position, not the enemy's current position. Here is how the updated firing logic should look: // Inside CombatSystem's tower firing loop, after if (targetTransform) { // --- START of new Prediction Logic --- var enemyMovement = Game.EntityManager.componentStores['MovementComponent'][towerAttack.target_id]; var enemyTransform = targetTransform; // for clarity var projectileSpeed = 200; // Use a constant for prediction // 1. Estimate time for projectile to reach the enemy's CURRENT position var distance = Math.sqrt(Math.pow(enemyTransform.x - towerTransform.x, 2) + Math.pow(enemyTransform.y - towerTransform.y, 2)); var timeToIntercept = distance / projectileSpeed; // 2. Find the enemy's next waypoint to determine its velocity vector var nextWaypoint = Game.PathManager.currentPath[enemyMovement.path_index]; var enemyVelocityX = 0; var enemyVelocityY = 0; if (nextWaypoint) { var waypointDX = nextWaypoint.x - enemyTransform.x; var waypointDY = nextWaypoint.y - enemyTransform.y; var waypointDist = Math.sqrt(waypointDX * waypointDX + waypointDY * waypointDY); if (waypointDist > 0) { enemyVelocityX = (waypointDX / waypointDist) * enemyMovement.speed; enemyVelocityY = (waypointDY / waypointDist) * enemyMovement.speed; } } // 3. Predict the enemy's future position var futureX = enemyTransform.x + enemyVelocityX * timeToIntercept; var futureY = enemyTransform.y + enemyVelocityY * timeToIntercept; // --- END of new Prediction Logic --- // 4. Calculate the REAL firing direction towards the future position var fireDX = futureX - towerTransform.x; var fireDY = futureY - towerTransform.y; var fireDist = Math.sqrt(fireDX * fireDX + fireDY * fireDY); var directionX = fireDX / fireDist; var directionY = fireDY / fireDist; // Create projectile with this new direction // ... (the rest of the projectile creation code is the same)

I apologize, my last fix was incomplete. The projectile movement calculation is still incorrect, causing them to move too fast. We need to make the movement frame-rate independent. Please find the CombatSystem, in the projectile update loop. Modify the two lines that calculate the movement to account for the frame time (delta time, which is roughly 1/60th of a second). The updated code should look like this: // Inside the projectile update loop in CombatSystem... } else { // Move projectile using stored direction var moveX = projectileComp.directionX * projectileComp.speed * (1/60); var moveY = projectileComp.directionY * projectileComp.speed * (1/60); projectileTransform.x += moveX; projectileTransform.y += moveY; } Additionally, let's revert the projectile speed to a higher value now that the movement calculation is correct. In the ProjectileComponent factory function, please change the default speed from 8 back to 200.
User prompt
The enemies are not dying because the projectiles are moving too fast and tunneling through them. We need to fix the collision detection logic in the CombatSystem. Please find the CombatSystem's update loop for projectiles. Replace the old collision check if (distance < 5) with a new, more robust check. The new logic should see if the distance to the target is less than or equal to the speed of the projectile. The updated if statement should look like this: // Inside the projectile update loop in CombatSystem... // OLD, BUGGY CODE TO BE REPLACED: // if (distance < 5) { // NEW, CORRECTED CODE: var speedThisFrame = projectileComp.speed * (1 / 60); // Calculate distance traveled in one frame if (distance <= speedThisFrame) { // [The rest of the hit/damage/kill logic remains the same] // ... } Please also reduce the projectile speed to a more reasonable value for now. In the ProjectileComponent factory function, change the default speed from 200 to 8. And in the CombatSystem when creating a projectile, use this new default speed.

The Game Over system works perfectly! I've noticed that enemies are not taking damage. I realize we forgot to give them a HealthComponent. Please find the Game.Systems.WaveSpawnerSystem. Inside its update function, where it creates a new enemy, please add a HealthComponent. The enemy creation block should be updated to include it, like this: // Inside WaveSpawnerSystem.update... if (this.spawnedInSubWave < currentSubWave.count) { var enemyId = Game.EntityManager.createEntity(); var transform = Game.Components.TransformComponent(0 * 64, 30 * 64); var movement = Game.Components.MovementComponent(2, 0); var render = Game.Components.RenderComponent('enemy', 1, 1.0, true); var health = Game.Components.HealthComponent(30, 30); // 30 current, 30 max var enemy = Game.Components.EnemyComponent(5, 1); Game.EntityManager.addComponent(enemyId, transform); Game.EntityManager.addComponent(enemyId, movement); Game.EntityManager.addComponent(enemyId, render); Game.EntityManager.addComponent(enemyId, health); // Add the health component Game.EntityManager.addComponent(enemyId, enemy); this.spawnedInSubWave++; this.spawnTimer = 0; Game.GameplayManager.enemiesSpawnedThisWave++; }

The wave progression system is working perfectly! This is the final step to create a complete, playable game loop. 1. Create a GameManager for Win/Loss States: In the // === SECTION: GLOBAL MANAGERS === block, create a new GameManager object. This will handle the highest-level game states. Give it an isGameOver: false property. Give it an init() method that subscribes to the GameOverEvent. Give it an onGameOver(event) handler. 2. Implement GameManager Logic: Inside onGameOver(event), it should set this.isGameOver = true; and then call the engine's built-in game over screen: LK.showGameOver();. 3. Prevent Actions After Game Over: In the main game.update function, add a check at the very top: if (Game.GameManager.isGameOver) { return; } This will freeze the game when the player loses. 4. Fix a Small Bug: In Game.GameplayManager.onEnemyKilled, the EnemyKilledEvent gives us the gold_value. Let's use it! Change this.addGold(event.gold_value); in ResourceManager.onEnemyKilled to use the EnemyComponent's value instead. When the enemy is killed in the CombatSystem, it should publish the gold_value from the enemy's EnemyComponent. The CombatSystem's EnemyKilledEvent should look like this, fetching the gold_value from the dead enemy's EnemyComponent: // Inside CombatSystem when an enemy is killed... var enemyComp = Game.EntityManager.componentStores['EnemyComponent'][projectileComp.target_id]; var goldValue = enemyComp ? enemyComp.gold_value : 10; Game.EventBus.publish(Game.Events.EnemyKilledEvent(projectileComp.target_id, goldValue)); 5. Initialize the GameManager: In the // === SECTION: DIRECT GAME INITIALIZATION === block, add the final init call: Game.GameManager.init();

The WaveSpawnerSystem is working great! Now let's implement the logic for completing a wave and allowing the player to start the next one. 1. Create a GameplayManager: In the // === SECTION: GLOBAL MANAGERS === block, create a new Game.GameplayManager object. It needs to track wave progress: enemiesSpawnedThisWave: 0 enemiesKilledThisWave: 0 enemiesLeakedThisWave: 0 init(): An init method to subscribe to events. onEnemyKilled(event): A handler for the EnemyKilled event. onEnemyReachedEnd(event): A handler for the EnemyReachedEnd event. 2. Implement GameplayManager Logic: Inside init(), subscribe to the EnemyKilled and EnemyReachedEnd events. The onEnemyKilled handler should increment this.enemiesKilledThisWave. The onEnemyReachedEnd handler should increment this.enemiesLeakedThisWave, call Game.ResourceManager.loseLife(1), and destroy the enemy entity. After incrementing either counter, both handlers must check if the wave is over using the condition: if (this.enemiesKilledThisWave + this.enemiesLeakedThisWave === this.enemiesSpawnedThisWave) If the wave is over, it should publish a WaveCompletedEvent, reset its counters, and make the "Start Wave" button visible. 3. Update WaveSpawnerSystem: Modify the WaveSpawnerSystem to update the GameplayManager. When an enemy is spawned, it must increment Game.GameplayManager.enemiesSpawnedThisWave. 4. Create "Start Wave" Button: In the // === SECTION: DIRECT GAME INITIALIZATION === block, create a startWaveButton using new Text2('START NEXT WAVE', ...). Add it to the bottom-center of the GUI: LK.gui.bottom.addChild(startWaveButton); Make it invisible by default: startWaveButton.visible = false; Give it a down handler that calls Game.Systems.WaveSpawnerSystem.startNextWave() and hides the button again. 5. Initialize the New Manager: Finally, add Game.GameplayManager.init(); to the initialization block.

The combat and pathfinding are working perfectly. It's time to create a system for spawning waves of enemies. 1. Create Enemy Metadata Component: In Game.Components, add a new component to store enemy-specific data: EnemyComponent: function(goldValue, livesCost) { return { name: 'EnemyComponent', gold_value: goldValue || 5, lives_cost: livesCost || 1 }; } 2. Create Wave Data Structures: We need a data structure to define the waves. Please add this new section of code after the Game.Systems object: // === SECTION: GAME DATA === Game.WaveData = [ // Wave 1 { wave_number: 1, sub_waves: [ { enemy_type: 'enemy', count: 10, spawn_delay: 1.0, start_delay: 0 } ] }, // Wave 2 { wave_number: 2, sub_waves: [ { enemy_type: 'enemy', count: 15, spawn_delay: 0.8, start_delay: 0 } ] }, // Wave 3 { wave_number: 3, sub_waves: [ { enemy_type: 'enemy', count: 20, spawn_delay: 0.5, start_delay: 0 } ] } ]; 3. Create the WaveSpawnerSystem: In Game.Systems, add a new WaveSpawnerSystem. It should have: Properties: currentWaveIndex: -1, isSpawning: false, spawnTimer: 0, subWaveIndex: 0, spawnedInSubWave: 0. startNextWave(): A function that increments currentWaveIndex, resets the spawner's state variables, and sets isSpawning = true. update(): The main logic loop. If isSpawning is true, it should handle the timers (spawnTimer, start_delay, spawn_delay) and create new enemy entities based on the data in Game.WaveData. When an enemy is created, it must be given all its necessary components (Transform, Movement, Render, Health, and the new EnemyComponent). 4. Integrate with the Game: Remove the old "Create a test enemy" code from the // === SECTION: DIRECT GAME INITIALIZATION === block. In its place, call Game.Systems.WaveSpawnerSystem.startNextWave(); to begin the first wave automatically. In the main game.update function, add a call to Game.Systems.WaveSpawnerSystem.update();
