RTSUnit Health Bar Color Damage

This is a simple modification to the existing RTSUnit health bar rendering that makes the bar show green for healthy, yellow for medium damage, and red for heavy damage.

In guiRTSTSCtrl.h

replace

ColorF   mDamageFillColor;

with

ColorF   mDamageFillColorHealthy;
ColorF   mDamageFillColorMedium;
ColorF   mDamageFillColorHeavy;

In guiRTSTSCtrl.cc

replace

mDamageFillColor.set( 0, 1, 0, 1 );

with

mDamageFillColorHealthy.set( 0, 1, 0, 1 );
mDamageFillColorMedium.set( 1, 1, 0, 1 );
mDamageFillColorHeavy.set( 1, 0, 0, 1 );

replace

dglDrawRectFill(rect, mDamageFillColor);

with

dglDrawRectFill(rect, damage<0.33f?mDamageFillColorHeavy:damage<0.66f?mDamageFillColorMedium:mDamageFillColorHealthy);

That's it, you should now have RTSUnit health bars that show green, yellow, or red based on the unit's damage level.
