Me and my friend were just checking stuff out, and he wanted to make a pendulam. eventually we wanted the pendulam to move a really short distance realllly fast to throw you, and we set it up with a button to control it. everything worked pretty bad, but the weird thing was when you you used the flashlight on the func_button we made (textured) it would turn black permantly, or so we thought, until we saw a black burn mark on the ceiling. When we put the flashlight on this it disappeared, but the button was no longer black. We than flashlighted the button again, and it turned black again, causing the explosion mark on the ceiling again. I wanted to upload the map, but one thing led to another and before long too much was changed and it didnt work anymore
