Size of a ollider

Hi, I am following a tutorial about slope in my character movement. I am pretty new in scripting.

The guide is using a 2D collider the ".size" function to get the size of it collider. The problem is I can't use a 2D collider in my game and I can't find a way the replicated the for a 3D collider.

Here is the link of the tutorial if needed at 2:30

 

3D colliders have "bounds" instead. The Bounds struct has an "extents" Vector3 which is its size.

 

so I would write something like
colliserSize = cc.bounds;
?

 

Should be cc.bounds.extents

 

i see no red. thx ill keep in touch if it works fine late on
