Is there a built-in Camera feature in the PushButton Game Engine?

I’ve been experimenting with a game engine for Flash development. I’m trying to create a camera that follows the main character, similar to how the camera follows Mario in classic platformers. I’ve looked through the documentation but couldn’t find anything about a camera feature.

Does anyone know if this engine has a built-in camera system? If not, has anyone created a custom component for this purpose? I’d really appreciate any tips or guidance on how to implement this functionality.

Here’s a basic example of what I’m trying to achieve:

class GameCamera {
  private var target: GameObject;
  private var x: Number;
  private var y: Number;

  public function follow(obj: GameObject): void {
    target = obj;
  }

  public function update(): void {
    if (target) {
      x = target.x - (screenWidth / 2);
      y = target.y - (screenHeight / 2);
    }
  }
}

Is there something similar built into the engine, or do I need to create this from scratch?

I’ve used PushButton for a couple of projects, and you’re right, there’s no built-in camera system. Your code is a good starting point, but you might want to consider adding some extra features to make it more robust. One thing that helped me was implementing a ‘lookahead’ system, where the camera slightly shifts in the direction the player is moving. This gives a better sense of what’s coming up in the game world.

Another useful addition is camera zooming. You can tie this to game events or player actions to create more dynamic gameplay moments. Just be careful with performance - excessive zooming can slow things down on some devices.

If you’re looking for more advanced features, consider implementing a multi-target camera that can focus on multiple game objects. This can be useful for multiplayer games or when you want to keep both the player and important objects in view.

Don’t forget to test your camera thoroughly in different scenarios. Edge cases like rapid player movement or teleportation can reveal issues you might not have considered initially.

hey nova56, i dont think pushbutton offers a built-in cam. your code is a solid start, though. consider adding some smoothing for better motion and checking user forums for custom scripts. best of luck with ur game!

I’ve worked extensively with PushButton, and I can confirm there’s no built-in camera system. Your approach is on the right track. To enhance it, consider implementing edge boundaries to prevent the camera from showing areas outside your game world. Also, adding a slight delay to the camera movement can create a more dynamic feel. Here’s a tip: use interpolation for smoother transitions. If you’re struggling, the PushButton community forums have some helpful threads on custom camera implementations. Keep iterating on your solution, and you’ll have a solid camera system in no time.
