Take a look at this vid. It shows the ball colliding with the hoarding and it gets stuck...

This example show the ball colliding with the rear of the hoarding and it rebounds in the wrong direction...

However, as you can see, if the ball bounces off the stadium wall it responds fine. This is also the case if I align the advert hoardings perfectly horizontal or verticle which makes me think it is a bug in minib3d.

This is the code i'm using...

Collisions(CTYPE_BALL, CTYPE_GOALNET, 2, 1)
		Collisions(CTYPE_BALL, CTYPE_GOALPOST, 2, 1)
		Collisions(CTYPE_BALL, CTYPE_WALL, 2, 1)
		Collisions(CTYPE_BALL, CTYPE_STADIUM, 2, 1) ' Hoardings use this.

For Local i:Int = 1 To CountCollisions(mesh)
				Local ent:TEntity = CollisionEntity(mesh, i)

				Local Nx# = CollisionNX(mesh, 1) 
				Local Ny# = CollisionNY(mesh, 1) 
				Local Nz# = CollisionNZ(mesh, 1) 
			
				Local VdotN# = vecVelocity.x*Nx# + vecVelocity.y*Ny# + vecVelocity.z*Nz#
									
				Local NFx# = -2.0 * Nx# * VdotN# 
				Local NFy# = -2.0 * Ny# * VdotN# 
				Local NFz# = -2.0 * Nz# * VdotN# 
										
				Local bounce:Float = 0.8
				vecVelocity.x = (vecVelocity.x + NFx#) * bounce
				vecVelocity.y = (vecVelocity.y + NFy#) * bounce
				vecVelocity.z = (vecVelocity.z + NFz#) * bounce
			Next

Any idea?
