ZScript: Status Bar Questions

[Matt]

Does anyone know how to get powermorph duration?

The same as any other powerup duration, I would speculate? (sorry I don't know for sure)


I'm thinking of possibly implementing a first focal plane reticle to at least one of the guns in HD.

Is there a way to dynamically crop an image, so I wouldn't have to have a different TEXTURES entry for every possible magnification?

Try SetClipRect().

Are you trying to scale? Why not actually scale then?

[Matt]

ZZYZX: I'm trying to scale an image up, but then also crop off the parts of the image that extend beyond certain bounds of the screen.

In this particular situation if I simply scaled the crosshair image you'd see the ends of the crosshair sticking out from where the sides of the scope ought to be.

Blue Shadow: Thanks! That was the function I thought I saw somewhere but couldn't remember the name...

I'm looking at the code for SetClipRect now but I don't see anything indicating what exactly any given SetClipRect call is supposed to clip. I do see, however, some stuff in the source code like "screen->SetClipRect" and whatnot. I take it there's some way to set up some sub-entity for this? Or is this restricted to affecting the entire HUD?

EDIT: Or do I have to call SetClipRect twice, once for this thing and once to set it back to normal to draw other stuff?

[Blue Shadow]

Would studying how it's used in DrawBar help?

A general practice which I hopefully think is correct is to always save the previous clipping rectangle first so that it can be restored later when you are done clipping your own graphics.

[Blue Shadow]

Yeah, that's what DrawBar does.

Thanks guys! I've finally implemented this and it works exactly as hoped!

Is there any way to colourize an image on the HUD (other than to create a green version of it and mark it as translatable)?
