ELEMENT_SPRITE

ELEMENT_SPRITE, like ELEMENT_MOVING_IMAGE, moves an element in X and Y directions and uses a mask to hide parts of the element. The difference is that ELEMENT_SPRITE can rotate an element around a pivot point. For ELEMENT_SPRITE, POS (position) is interpreted normally (as the upper-left corner position); OFS (offset) is the center of the sprite—the center of the texture maps to this point.

Textures used for ELEMENT_SPRITE must be 256 x 256. When the gauge is loaded, the resource_id specifies the image to use for the texture. The resource_id + 3 specifies the mask image. The mask doesn't have to be a specific size. The mask is placed on the gauge using the position member. The texture slides and rotates underneath the mask.

Element transformations occur in the following order:

1. Rotate, based on source_var_0
   
   
2. Scale, based on texture_scale_x and texture_scale_y
   
   
3. Transpose, based on source_var_x and source_var_y
