loadShader(name: string | null, vert?: string, frag?: string): Asset<ShaderData>

Load a shader with vertex and fragment code.

// default shaders and custom shader format
loadShader("outline",
`vec4 vert(vec2 pos, vec2 uv, vec4 color) {
    // predefined functions to get the default value by KAPLAY
    return def_vert();
}`,
`vec4 frag(vec2 pos, vec2 uv, vec4 color, sampler2D tex) {
    // turn everything blue-ish
    return def_frag() * vec4(0, 0, 1, 1);
}`, false)
