geo()

Geometry * yourgame::gl::SpriteGrid::geo ( ) const

inline

Returns

pointer to geometry object (m_geo)

make()

int yourgame::gl::SpriteGrid::make	(	const yourgame::gl::Texture *	atlas,
		const std::vector< std::string > &	tiles,
		unsigned int	width,
		float	gridWidth,
		float	gridHeight
	)

creates grid geometry in x-y plane (z = 0)

• planar grid in x-y plane (z=0), 2 ccw trianlges per tile
• drawing: bind texture manually and get geometry for drawing via geo()
• aspect ratio taken from first tile
• atlas is only used for geometry creation, pointer is not kept
• atlas should have only 1 texture

Parameters

atlas	atlas, the coordinates are taken from
tiles	names of tiles in atlas, in row-major order
width	number of tiles per row. if = 0, all tiles in 1 row
gridWidth	desired width of entire grid. if <= 0.0f, aspect ratio and gridHeight (if > 0.0f) used
gridHeight	desired height of entire grid. if <= 0.0f, aspect ratio and gridWidth (if > 0.0f) used

Returns

error (0 on success)
