Doubts about Collision size...?

Ok, it seems a stXXX question, but...

How do I know how much I should set the number of the collision size?

I always set it randomly... i set them big (45+) if i want them not being able to go through buildings

but now i'd like to know how much to set, and if it's related to its scaling value and selection scale...

thx

Some heroes are usually around 30. 46 is pretty big. Scaling value is how big the circle is when you click them. They are not releated to going through buildings, but it looks weird when you select a teeny tiny unit and it has a huge selection circle. Or a golem sized shadow.

Edit: Listen to him. I'm dumb.

The collision size is actualy the diameter of the area it takes up (centenered on the unit) if you want to know how big that is just turn on the grid and the Large grid is 512, the medium is 128 and think the small is 16 (might be 32).

Scaling value is not the size of the selection circle, but just what it says it is. It is the value that the model is scaled.

Selection scale is the scaling value of the selection circle.

Peons and low-level (i.e. small) units are 16.00. They are the ones that can squeak between buildings. A lot of heros are 32.00, although a couple (like the Tauren Chieftain) are 48. They seem to like multiples of 16, anyhow.

It should be noted that some seem to have a collision size just smaller than a multiple of 16. For example, 31.00. I'm not sure why this is, but I'm guessing that there are situations where 32.00 is exactly too big to fit in a space, but a slightly smaller value does it.

BTW, Collision Size is absolute. It has nothing to do with the size of the model, and it's not related to the Selection Scale. Selection Scale is also absolute. Making it 4.00 on one unit will make it precisely the same size as 4.00 on a different unit, regardless of their Collision Size or model Scale.
