I would Like to know if when I set the alpha (entity) to 0 is the same of Free Entity. I'm talking about triangle limits.

EntityAlpha sets an entity's transparency (ex: .5 is 50% visible) - so 0 would be invisible but regardless it still exists. FreeEntity deletes an entity from memory. I am not sure if triangles are rendered at EntityAlpha 0 but HideEntity definitely prevents an entity's tris from rendering.

So, I can prevent it using simple logic anyway. I can HideEntity save the data into the array and load again at the moment of the entity has to appear again. EntityAlpha could work...... to prevent spending some hours working on it. Lol! :D LOL :) Thanks!

Entity with alpha zero does not render but can still be iinvolvd in collisions whereas a hidden entity does not contribute to collision calculations.
