Colision while creating actor

Postby Game A Gogo » Sat Jul 21, 2007 1:42 am

If an actor is created while it has a collision on another actor, it will not receive colision events when colliding whit the actor, this is a big problem for what I am developing, here is a sample GED:

Hey GOGO, I had the exact same problem in Hull Breach, with asteroids no less... What I did to solve the problem was have each roid's create-actor event (collision state set to disable) and a timer created for like 250mm. That timer event turned the collision state back on, and it seemed to fix the problem with my asteroids. You may need to adjust the 250mm to more or less depending on the size of the sprites/velocity. Hope this works in your case.

Its not really solvable. I recall this problem from long ago. Basically, the collision state is unknowable prior to, or during the creation of the actor, as it is the actor that checks and handles the result of collision. Its like you trying to remember a time before you were born.

What you can do is check the location before creating the actor. What would be nice is to have GE pass a value to a created actor. By this means, you could, in the create actor event, set collision to zero, and then immediately flip it on, or have it act out the collision regardless.

Of course, in general you would just try and avoid this. Such as making the first frame invisible, or only covering an area where it won't collide.

Thats brilliant Dillo. Make a special transparent animation, set it to that, then flip to the regular one on the first draw, and it it should detect the collision.
