collision problem

Hi,

I've been working on a game and I tested the collision system at the beginning. After doing an update of mini3D, it seems to have stopped working. I've made a simple program to test collision and it I can't get it to work. Can anyone have a look, test this and see if the spheres collide? And if not, why not.

Thanks.

Import sidesign.minib3d


Graphics3D 800,400

Collisions 1,1,1

Global a = CreateSphere()
EntityRadius a, 1.1
EntityType a,1
PositionEntity a,-2,0,0
UpdateWorld

Global b = CreateSphere()
EntityRadius b,1.1
EntityType b,1
PositionEntity b,2,0,0
UpdateWorld

Global c = CreateCamera()
PositionEntity c,0,0,-5



While KeyDown(KEY_ESCAPE) = False

	Cls

	'PointEntity c,a
	MoveEntity a,0.01,0,0
	
	UpdateWorld
	RenderWorld
	
	Flip

It probably because the source and destination types are the same. If you change the destination type to 2 it should work.

I tried that, it didn't work. Any other ideas? It looks like it should work doesn't it? It used to work until I updated. I rolled back to 45 and it still doesn't work. Curiously the sliding collision example provided with mini3d does work.

Ah, actually, the current version of MiniB3D doesn't support 'responses' (sliding/stop) with sphere-sphere collisions - it just detects them.

ah!
that would explain it. Would that be using EntityCollided? Everything exactly the same except no automated response?
Yes, that seems to be the case (just checked.)
Thanks Si

I should probably mention that the next version uses Blitz3D's source code for the entire collision system, so I wouldn't spend a lot of time on workarounds.

Will it allow moving collisions? I mean both entities moving and colliding?

It's the same as B3D.

Any chance you can keep in a callback that has no response for things like phantom volumes? Also, any idea when this will be ready?

Thanks,

B
