Chapter 29 ■ Widget Reference 1143Texture loading is normally synchronous, so that UI objects are not shownpartially textured while loading; however, non-blocking (asynchronous)texture loading may be desirable in some cases where large numbers of texturesneed to be loaded in a short time. This feature is used in the default UI’sicon chooser window for macros and equipment sets, allowing a large numberof icon textures to be loaded without causing the game’s frame rate to stagger.Arguments:nonBlocking—True to allow the texture object to load its imagefile in the background; false (default) to halt the game enginewhile the texture loads (boolean)SetRotationRotates the texture image.Texture:SetRotation(radians)This is an efficient shorthand for the more complex Texture:SetTexCoord().Arguments:radians—Amount by which the texture image should be rotated (in radians;positive values for counter-clockwise rotation, negative for clockwise) (number)SetTexCoordSets corner coordinates for scaling or cropping the texture image.Texture:SetTexCoord(left, right, top, bottom) or iTexture:SetTexCoord(ULx, ULy, LLx, LLy, URx, URy, LRx, LRy)See example for details.Arguments:left—Left edge of the scaled/cropped image, as a fraction of the image’s widthfrom the left (number)right—Right edge of the scaled/cropped image, as a fraction of the image’swidth from the left (number)top—Top edge of the scaled/cropped image, as a fraction of the image’s heightfrom the top (number)bottom—Bottom edge of the scaled/cropped image, as a fraction of the image’sheight from the top (number)ULx—Upper left corner X position, as a fraction of the image’s width from theleft (number)ULy—Upper left corner Y position, as a fraction of the image’s height from thetop (number)LLx—Lower left corner X position, as a fraction of the image’s width from theleft (number)LLy—Lower left corner Y position, as a fraction of the image’s height from thetop (number)URx—Upper right corner X position, as a fraction of the image’s width from theleft (number)
