Thank you for your co-operation.

I get error when i click on screen at runtime.
That is : Crash in creat : you=ent_create(@4,0,10)
Why ?

When i change layer 10 to NULL(you = ent_create("earth.mdl",0, NULL);)
than error gone entity creat but not excecty match mouse position.
It is just overlaping in one layer horizontaly.
Sorry i cant understand your third point properly.

please help.
