help with 2 entitys

[gravelhunter]

how do write an if command where

if entity one hits entity2 then entity2
SetCollisionGroup( COLLISION_GROUP_WORLD )

[Gryphian]

Can you be more specific? If they are two seperate entity classes then just:
[lua]
//Entity1's touch
function ENT:Touch(ent)
if ent:GetClass() == "class_of_entity2" then
ent:SetCollisionGroup( COLLISION_GROUP_WORLD )
end
end
[/lua]
