Create overlay from core images.

[Xara]

I guess it's possible to create overlays from existing core images. For example, you can take the items/potion-red.png, shrink it and put it at the corner.

I'm not sure if anyone has done similar things through image path functions WML. Is there any codes that I can borrow?

I am doing exactly that in OoA. If you pick up an item (say, a sword) the following macro takes the image, shrinks it and places it in the top right corner above the unit sprite:

Code: Select all

#define ABILITY_ICON_OVERLAY IMAGE
	[effect]
		apply_to=overlay
		add=misc/blank-hex.png~BLIT({IMAGE}~CROP(14,14,42,42)~SCALE(16,16),42,0)
	[/effect]
#enddef

You might change values as needed

Thanks, it works nicely.
