Select "Create Entity" +3. Name it "Player" +4. In the Inspector panel, set its position to (0, 0) +5. Add a Sprite component: + - Click "Add Component" > "Sprite" + - Select your player sprite +6. Add a Collider component: + - Click "Add Component" > "Collider" + - Set Width and Height to match your sprite +7. We'll add a script later + +### Step 5: Creating Coins + +1. Create a new empty entity named "Coin" +2. Add a Sprite component with your coin sprite +3. Add a Collider component +4. Position it somewhere in the scene +5. Duplicate this coin a few times and place them around the scene + +### Step 6: Creating Player Script + +1. Create a new file in `scripts/PlayerController.jl` with the following code: + +```julia +using JulGame +using JulGame.Math + +struct PlayerController <: Script + speed::Float64 + score::Int + + PlayerController() = new(200.0, 0) +end + +function update(script::PlayerController, entity) + # Handle movement + moveDirection = Math.Vector2(0, 0) + + if MAIN.input.isKeyPressed(SDL2.SDLK_RIGHT) + moveDirection.x += 1 + end + if MAIN.input.isKeyPressed(SDL2.SDLK_LEFT) + moveDirection.x -= 1 + end + if MAIN.input.isKeyPressed(SDL2.SDLK_DOWN) + moveDirection.y += 1 + end + if MAIN.input.isKeyPressed(SDL2.SDLK_UP) + moveDirection.y -= 1 + end + + # Normalize and apply movement + if moveDirection.x != 0 || moveDirection.y != 0 + moveDirection = Math.normalize(moveDirection) + entity.transform.position += moveDirection * script.speed * DELTA_TIME + end + + # Display score + using JulGame.UI.ImmediateUIModule + immediate_text("score_display", + "Score: $(script.score)", + "Arial.ttf", + 24, + Math.Vector2(20, 20)) +end + +function onCollisionEnter(script::PlayerController, entity, other) + # Check if we collided with a coin + if startswith(other.name, "Coin") + # Increase score + script.score += 1 + + # Remove the coin + MAIN.scene.removeEntity(other) + end +end +``` + +### Step 7: Adding the Script to the Player + +1. Select the Player entity +2. In the Inspector, click "Add Component" > "Script" +3. Enter "PlayerController" as the script name + +### Step 8: Running the Game + +1. Save your scene +2. Create a `Run.jl` file in your project root with: + +```julia +using JulGame +using JulGame.SceneManagement.SceneLoaderModule + +function main() + # Define window properties + windowConfig = WindowConfig( + width = 800, + height = 600, + title = "My First JulGame", + fullscreen = false + ) + + # Load the main scene + initialScene = loadScene("scenes/MainScene.json") + + # Start the game + MainLoop.startMainLoop(windowConfig, initialScene) +end + +main() +``` + +3. Run your game: + +```bash +cd path/to/your/project +julia Run.jl +``` + +Congratulations! You've created a simple game with JulGame. + +## Tutorial 2: Adding Animation + +Building on our simple game, let's add animations to make it more dynamic. + +### Step 1: Prepare Animation Frames + +For animation, you'll need a sprite sheet or multiple frames. Place these in your `assets/images/` folder. + +### Step 2: Add an Animator Component + +1. Select the Player entity +2. Click "Add Component" > "Animator" +3. Create a new animation: + - Name: "Walk" + - Select your sprite frames + - Set frame duration (e.g., 0.1 seconds per frame) + - Set to loop + +### Step 3: Update the Player Script + +Modify `PlayerController.jl` to handle animations: + +```julia +function update(script::PlayerController, entity) + # Get references to components + animator = entity.getComponent("Animator") + + # Handle movement + moveDirection = Math.Vector2(0, 0) + + if MAIN.input.isKeyPressed(SDL2.SDLK_RIGHT) + moveDirection.x += 1 + end + if MAIN.input.isKeyPressed(SDL2.SDLK_LEFT) + moveDirection.x -= 1 + end + if MAIN.input.isKeyPressed(SDL2.SDLK_DOWN) + moveDirection.y += 1 + end + if MAIN.input.isKeyPressed(SDL2.SDLK_UP) + moveDirection.y -= 1 + end + + # Normalize and apply movement + if moveDirection.x != 0 || moveDirection.y != 0 + moveDirection = Math.normalize(moveDirection) + entity.transform.position += moveDirection * script.speed * DELTA_TIME + + # Play walk animation + AnimatorModule.play(animator, "Walk") + else + # Stop animation when not moving + AnimatorModule.stop(animator) + end + + # Flip sprite based on direction + if moveDirection.x < 0 + entity.transform.scale.x = -1 # Flip horizontally + elseif moveDirection.x > 0 + entity.transform.scale.x = 1 # Normal orientation + end + + # Score display code (same as before) + using JulGame.UI.ImmediateUIModule + immediate_text("score_display", + "Score: $(script.score)", + "Arial.ttf", + 24, + Math.Vector2(20, 20)) +end +``` + +## Tutorial 3: Adding Sound + +Let's add sound effects and background music to our game. + +### Step 1: Prepare Audio Files + +Place your audio files in the `assets/audio/` folder: +- Background music (e.g., `music.mp3`) +- Coin collection sound (e.g., `coin.wav`) + +### Step 2: Add Background Music + +1. Create a new empty entity named "BackgroundMusic" +2. Add a SoundSource component: + - Click "Add Component" > "SoundSource" + - Select your music file + - Check "Loop" to make it play continuously + - Set the volume (e.g., 0.5) + +### Step 3: Update the Player Script for Sound Effects + +Modify `PlayerController.jl` to play a sound when collecting coins: + +```julia +function onCollisionEnter(script::PlayerController, entity, other) + # Check if we collided with a coin + if startswith(other.name, "Coin") + # Increase score + script.score += 1 + + # Play coin sound + SoundSourceModule.playSoundOnce("assets/audio/coin.wav", 1.0) + + # Remove the coin + MAIN.scene.removeEntity(other) + end +end +``` + +## Next Steps + +Now that you've completed these basic tutorials, you can: + +1.
