Spawn Actor

hambuerger7

So in my game I'm making a game with an actor that spawns another actor wherever the player flicks/swipes the screen and an actor that moves right and controls camera. It works perfectly fine at first, but once the scene moves right, it only spawns them at the beginning of the scene.

How do I fix this?

Thanks in advance.

How are you setting up the spawn actor behavior? What are you using for the x position? Do you have it set to relative to the scene or to the actor? You may need an x offset depending on the position of the camera.

This is the code for spawning:

When game.Up>50 (thats when they flick the screen)

Spawn Actor: Paper in Front of Actor
Direction: 0.0 relative to actor
Position: game.releaseX (Mouse position X), 0 relative to scene.

So I figured out that it wasn't working because it was spawning to the actual position in the scene.

Ex:
If the camera was showing the domain of [200,520] which would be literally on the iPhone [0,320] and I attempt to spawn it at (520,0), it will spawn at (320, 0) in relation to the scene.

How do I fix this?

That what I meant by an offset. You need to factor in the difference between the camera position and the onscreen position. I believe it's the attribute called Current Scene.Camera.Origin.X, but I could be wrong. If you unlock an actor in the scene, you'll get access to that attribute (and others related to the camera). Just stick one or more of those attributes in a Display Text behavior and then watch what the values are when you play the game. That should help you figure out what to add/subtract to make it work.

For some reason the game.camera.origin.x is staying at 0 while it moves
