API:CircleImageSetTexture

UI Lua API · CircleImage functions
Version: WAR 1.4.8

Sets the texture a CircleImage shows and which point of it is at the circle's centre.

CircleImageSetTexture(imageName, textureName, x, y)

Arguments

imageName: string – Name of a CircleImage window.
textureName: string – Name of the texture.
x, y: number – Pixel position in the texture that is drawn at the centre of the circle. Fractions are dropped.

Returns

Nothing.

Details

The texture is loaded by name and the circle is rebuilt with it.
How much of the texture around that point is visible depends on the window's size and the texture scale (see CircleImageSetTextureScale).
To show an icon from an icon texture, the stock UI adds half the window size to the icon's top-left corner (see the example).
