How to make an entities hull nocollide with that of the same entities hull?

How can I make the hull of entities of the same class (Example:npc_noob) no-collide with one another?

Try looking into [URL="https://wiki.garrysmod.com/page/GM/ShouldCollide"]GM:ShouldCollide[/URL] and [URL="https://wiki.garrysmod.com/page/Entity/SetCustomCollisionCheck"]GM:SetCustomCollisionCheck[/URL].

Set one or both of the entities to call GM:ShouldCollide() using [ENTITY]:SetCustomCollisionCheck(true), and then override that function to return false if [ENT1]:GetClass() == [ENT2]:GetClass().
