Collision with liquid

[Mackiiboy]

You could just put a block_box over it

Entites-> technical-> block box.

.
What will the block_box do?
I tried one and it does not seem to affect entities at all, just the player. A block_box_nonchar however, blocks both the player and entities, but then the entities wont be able to collide with the liquid at all which was not exactly what I was looking for, then it would be easier to select the collide-box [] on the waterplane.
If I have done something wrong with the block_boxes, please tell me.

If you check an article about the Entity Preview window @ Frictional Games Wiki, ya'll see that it's possible to check how an entity behaves in liquid in the ModelEditor. I tried to use the same settings as for a barrel for some entities with the preview mode, but they did not get any "good" behavior, they continued to bounce up and down. So, the thing I want to do is make it possible to make an entity to either sink or float when it collides with liquid, not bounce. I can't understand why the barrel works so good, but I will continue with the ModelEditor 'till I find out something or if you come up with something cool .
