Sprites going through floor

Hey guys, I am having problems with my sprites, well not specifically sprites but particle/geometry collisions in general.

I have a scene where some sprites (words) are going to be chucked out of a bag and land on the floor (its for a title sequence project).

I have set up the sprites with a radial and gravity fields to come out the bag and hit the floor, now my problem is that when the collide with the floor geometry they go half way through the floor and I need them to be on top of the floor, as if they were resting on the floor.

I have tried messing around with the geo connector attributs but can't seem to get the right outcome.

Many thanks in advance for any ideas.

Chris

The floor is the grey block.

The problem you are having is because the particles are really small compared to the sprite size so the collision occurs at the center of the sprite where the particle is.
You can offset the the collision in the attribute editor to take into acount the size of the sprite.

Re: Sprites going through floor

do not make the real floor colide with your geo.
make fake floor (disable from render) and let your particales colid with it you will have more control.

Hmm, ya thats what I thought but when i set up another plane it goes straight through it.

Its very odd.

Is the new plane set for collision?
Just duplicate the original plane for the ground and move the original up and turn off visability only.

Thanks jsprogg, it wasn't working off the bat, but I went into the Dynamic Relationships editor and did it that way with an invisible cube and it now works fine.

Cheers again,

Chris
