if(key_r)

pan_remove(panel);
}

P.S. Oh yeah i am using 1.70.1 V

i think you can remove panel that you create with pan_create and whay to remove, just make it invisible,it's easier

Try this (untested) instead.

No. This doesn't work. I get this error now.

If i am going to create a million panels and hide them all its would be just wrong. So i want to learn how to remove it then i create it.

Change it to this:


Now it should work!

IT WORKS. THANKS A LOT

When you create the new panel also it is necessary to check that the panel has not been created earlier. As consider that when you press a key on the keyboard, the condition "if (key_p)" is equally True in the several iterations of a cycle "while".

Sorry warkarma, Im getting sloppy...

Its ok EvilSOB it works now perfectly.
