Sprite:setStencilOperation

Available since: Gideros 2017.6

Description

Allows to set a stencil operation to be used when drawing this sprite.

   The table can contain the following fields:

• stencilClear: (boolean) whether the stencil should be cleared beforehand.
• stencilMask: (integer) the mask value used in stencil operations.
• stencilWriteMask: (integer) the mask value used when writing to stencil.
• stencilRef: (integer) the reference value used in stencil operations.
• stencilFunc: (integer) the stencil function to use.
• stencilFail: (integer) the stencil operation when stencil test failed.
• depthFail: (integer) the stencil operation when depth test failed.
• depthPass: (integer) the stencil operation when depth test has passed.

   Stencil function and operations code are defined in Sprite.STENCIL_xxx fields and correspond to the GL_xxx relevant values in OpenGL stencil documentation.
