virtual

Destructor.

@lua NA

Member Function Documentation

◆ beforeBlit()

virtual void beforeBlit ( )

inlinevirtual

Interface for custom action when before or after draw.

Reimplemented in Grid3D.

◆ initWithSize()

bool initWithSize ( const Vec2 & gridSize )

Init the Grid base.

Parameters

gridSize	the size of the grid.
texture	The texture used for grab.
flipped	whether or not the grab texture should be flip by Y or not.
rect	The effective grid rect.

◆ isActive()

bool isActive ( ) const

inline

Getter and setter of the active state of the grid.

◆ beforeDraw()

void beforeDraw ( )

Init and reset the status when render effects by using the grid.

◆ setGridRect()

void setGridRect ( const Rect & rect )

Set the effect grid rect.
