I want to load box with the pointer 'ent' Last edited by peteredlin; 12/29/10 16:09.

If i create 2 structs of the same type, and i want to use them for loading a fucntion with variables how must i write that function then? (that one and the same fucntion can work with multiple structs) Thanks in advance. Last edited by peteredlin; 12/29/10 17:25.
