Dynamic Slanted Unitframe Bar Textures?
 

Any idea how to do this?

I have no clue what you mean by "dynamic", but that's entirely possible using a custom statusbar texture.

Meaning the slant is dynamic rather than static, ie. it moves when the health value updates.

Bad & easy to achieve:


Good & what I'm asking about:

I can't offer a solution, but I remember looking at screenshots from zork's ringmod, and wondering how he made the spark truly radial. Maybe applicable, maybe not. :p

Yeah I remember that and I'd think something as simple as this would be very easy to achieve. We just need to know how.

Mess with TexCoord transformations. In particular, moving the upper left corner further left and the lower right corner out further right might provide the desired effect.

I would use two frames of the shaped texture, then cut the edges it instead of reducing the width using SetTexCoord.

Make 3 tga files:

• The white edge (a white irregular triangle)
• The red edge (a red irregular triangle)
• The white to red edge (where the white meets the red; two triangles of different colors)

Code 5 textures (from left to right):

• The white edge
• A white rectangle
• The white to red edge
• A red rectangle
• The red edge

You simply need to change the rectangles sizes according to the health you want to display.

On a side note, the "red to white edge" can be done programmatically by using the "white edge" and the "red edge" again (and rotating them).
