[][src]Enum ggez::conf::Backend

pub enum Backend {
    OpenGL {
        major: u8,
        minor: u8,
    },
    OpenGLES {
        major: u8,
        minor: u8,
    },
}

Possible backends. Currently, only OpenGL and OpenGL ES Core specs are supported, but this lets you specify which to use as well as the version numbers.

Defaults:

Backend::OpenGL {
    major: 3,
    minor: 2,
}

Variants

OpenGL

Defaults to OpenGL 3.2, which is supported by basically every machine since 2009 or so (apart from the ones that don't).

Fields of OpenGL

major: u8

OpenGL major version

minor: u8

OpenGL minor version

OpenGLES

OpenGL ES, defaults to 3.0. Used for phones and other mobile devices. Using something older than 3.0 starts to running into sticky limitations, particularly with instanced drawing (used for SpriteBatch), but might be possible.

Fields of OpenGLES

major: u8

OpenGL ES major version

minor: u8

OpenGL ES minor version

Methods

impl Backend[src]

pub fn version(self, new_major: u8, new_minor: u8) -> Self[src]

Set requested OpenGL/OpenGL ES version.

pub fn gl(self) -> Self[src]

Use OpenGL

pub fn gles(self) -> Self[src]

Use OpenGL ES
