I have changed the ‘hint’ icon for med pack as you can see in the below image:

All i did was edit the scripts/gfx_2d.shader
gfx/2d/healthhint
{
nomipmaps
nopicmip
{
map icons/iconw_medheal_select.tga
blendFunc GL_SRC_ALPHA GL_ONE_MINUS_SRC_ALPHA
rgbGen vertex
}
}
But i want to change the ammo pack ‘hint’ icon.
So i changed the shader as follows:
gfx/2d/ammohint
{
nomipmaps
nopicmip
{
map icons/iconw_ammopack_1_select.tga
blendFunc GL_SRC_ALPHA GL_ONE_MINUS_SRC_ALPHA
rgbGen vertex
}
}
The result is:

so the above script turns out not to be for ammo as ‘usableHint.tga’ is used
Any idea of the script that i need to ajust? i cant find it
