Collision Detection

[Unreal]

How do i make it so if a shape on screen hits another on screen shape, a message box would appear and say "oops!"?

Well, I think the easiest way of collision is a square-detection. Try this:

-
'Enemy and Shot are the two objects to check

'Collision from top-left
If Shot.Left + Shot.Width > Enemy.Left Then
If Shot.Top + Shot.Height > Enemy.Top Then

'Collision from bottom-right
If Shot.Left < Enemy.Left + Enemy.Width Then
If Shot.Top < Enemy.Top + Enemy.Height Then

'Code here

EndIf
EndIf

EndIf
EndIf
-

Of course you can take 2 if's together...

Hope this helps!
