Drawing part of a texture!

Sep 7, 2015 at 9:41 PM

Now sure if the Toolkit supports this and I am not very good at this. But say that I have a circle acting as a healthbar like in Diablo 3 and I would only want to draw a % of that circle image as health goes away sort of.

How would I do it with toolkit? I tried giving it an XMFLOAT2 position and a RECT that would store the updated part of the image it would need to draw but its not working. Does anyone know what math to apply here?

For the bars I was just using a drawing rect and changing but doing that with a circle is bad because it scales the entire circle and not decreases the view able area of the texture

For general raster shapes, the typical solution would be to use an animated texture or draw the circle dynamically using Direct2D (possibly using Win2D).

i am trying to provide a sourceRect which would act as the size of the image say its 1182 by 173 for example so its 0 0 1182 173

and then manipulate the 173 based on % value but dont need anything
