I’ve been experimenting with PushButton Game Engine for Flash game development and I need to implement a camera system that tracks the player character, similar to how the camera follows characters in platformer games. I know that other Flash game frameworks like Flashpunk include built-in camera functionality.
I’ve searched through the PushButton documentation but couldn’t find any mention of a camera component or system. Does PushButton Game Engine include camera support by default? If not, has anyone created a custom camera component for this engine? I would really appreciate any guidance on how to approach building a camera system from scratch or if there are existing solutions available. The camera needs to smoothly follow the player and handle basic features like boundaries and smooth movement.
yeah, pushbutton doesn’t support cameras out of the box - pretty annoying. I ended up building a custom solution that moves game objects in the opposite direction from the camera. works great once you get the math right!
PushButton doesn’t have built-in camera support, which surprised me when I started using it. I fixed this by building a simple camera manager that tracks an offset position in your game world. The trick is treating your whole scene as one big coordinate system and shifting everything during renders based on where the camera is. For smooth following, I added basic easing where the camera updates each frame toward the target using a damping factor - cameraX += (targetX - cameraX) * 0.1 works great. The hardest part was handling edge cases when players hit level boundaries, but you can fix this by calculating camera bounds from your level size minus viewport size. Performance-wise, it plays nice with PushButton’s component system.
Yeah, PushButton Game Engine doesn’t have a built-in camera system - at least it didn’t when I used it a few years ago. You’ll have to roll your own, but it’s not as tough as it sounds. I made a Camera class that handles viewport positioning and translates between world space and screen space. Just offset your rendering calls based on where the camera sits relative to your player. For smooth following, I threw in basic interpolation with a lerp function - makes the camera ease toward the target instead of jerking around. Boundary constraints? Just clamp the camera position within your level bounds. PushButton’s rendering system plays nice with this since you can apply the camera offset to display objects during rendering.
