I know I probably need a transparent PNG to create the Aim point gunsight thingee... but how to implement it in the code?

You mean like crosshairs in a FPS?

Warren

Make a texture that has an alpha channel (or a masked color) and draw it in the middle of the screen.

Rook Zimbabwe

Yes, but I want to use that to select things... using pickentity like...

Use CameraPick with the screen x,y co-ordinates of your crosshairs.

CameraPick ( camera,viewport_x#,viewport_y# )

Parameters:

camera - camera handle 
viewport_x# - 2D viewport coordinate 
viewport_z# - 2D viewport coordinate

That's the kind of valuable information that would have been more at home in your initial post.

Just FYI. :)

Don't mind EpicBoy, he's always like that :)
Anyways, I use LoadImage and DrawImage for crosshairs mostly.

I can't seem to get it to stick in the center of the screen I mean it flashes on once at the beginning but then goes bye bye!!!

You have to draw it every frame after RenderWorld.
