A destructor is present on this object, but not explicitly documented in the source.

Postblit

Copying this object is disabled.

A postblit is present on this object, but not explicitly documented in the source.

Members

Functions

add void add(in GLuint texture, in Vertex[] newVertices, in GLuint[] newIndices): Add some vertices and indices to the backend
clear void clear(in Color col): Clear the screen and the vertex and index buffers
flip void flip(): Flush the buffers and display the new screen
flush void flush(): Draw the current vertices and indices and clear the buffers
setShader void setShader(in string vertexShader, in string fragmentShader, in string transformAttributeName = "transform", in string positionAttributeName = "position", in string texPositionAttributeName = "tex_coord", in string colorAttributeName = "color", in string textureAttributeName = "tex", in string colorOutputName = "outColor"): Set the current shader and its attributes
