is there a way to make a custom button in the hud or to the  side of it with the crpl? if so how would one go about doing that?

look at the credits mission code for inspiration/guidance - that will show you how to display a hud type thing, and it is pretty easy from there.

Using SetScreenMode(TRUE) on a CRPL core has two effects:
1) The core is no longer affected by zooming in or out. Its size always stays the same.
2) The core is no longer anchored to a map cell. Instead, its position is defined relative to the bottom left corner of the game's window. Panning the map will not change the core's position. Example:

Code Select Expand


SetScreenMode(TRUE)
SetScreenCoords(0 0)
# the core will now stay in the bottom left corner of the game window
# zooming or panning the map will not change the core's position

SetScreenCoords(ScreenWidth div(2) ScreenHeight div(2))
# same as above, but the core will always be in the center of the window


And a more elaborate example. It's taken from one of my maps (Asteroid Belt, can be found here (http://knucklecracker.com/forums/index.php?topic=14436.0)). Basically, it creates a clickable button at the top left of the screen (screenshot in the thread linked above).

Code Select Expand
