2 and more actors. Collision detection?
« on: February 04, 2008, 10:21:49 AM »
What are the existing or recommended methods for doing this kind of stuff?
I want to have 2 actors as my game heroes.. want to switch them using LMBTN..
at the moment I can load them, switch between them, but they pass through each other...
I thought I could add a blocking region just under the current actor's feet when I switch to the other one..
but this could cause some troubles ... I mean if this block happens to be placed on the way between 2 waypoints..
or to be blocking a small single pass..
the second actor would get stuck..

any suggestions or alternatives? thanx in advance

We should take scaling into account..
gotto scale down the region if the actor is somewhere in the rear of the scene.
Has anybody done anything like this?

2D actors or 3D actors?

2d actors
Is there any difference between them, I mean considering the collision-detection issue?

Yup, 2D actors provide sort of a built-in collision detection (albeit undocumented). See this post for details.

Question: I want to have one actor "chase" the other and if the chasor meets the chasee then it triggers an event (ie. A player running from a badguy; if player gets caught he dies). How would I make an "ActorEntry" event trigger to those run-time regions?

Simply take actor1.X and actor1.Y and actor2.X and actor2.Y and if they are close enough, the chase is over, isn't it?

Ok now I feel like an idiot, I didn't know X and Y were members.

Excellent engine you got here consider me a donor! :)
