Okay, how would I go about creating this blood effect:

I need a blood splatter that comes out in a thin stream, then fills out, and finally falls to the floor in an arc. If you would give me a variable to randomize the direction it streches out at and moves to, that would be great, because I need to use that effect for a bunch of particles at once.

I also need to know how to put a blood splatter on an entity, where you shoot it at.

Thanks.
