Example 11 with GL20

use of com.badlogic.gdx.graphics.GL20 in project libgdx by libgdx.

the class ShaderProgram method setVertexAttribute.

	 * @param type the type, must be one of GL20.GL_BYTE, GL20.GL_UNSIGNED_BYTE, GL20.GL_SHORT,
	 *           GL20.GL_UNSIGNED_SHORT,GL20.GL_FIXED, or GL20.GL_FLOAT. GL_FIXED will not work on the desktop
	 * @param normalize whether fixed point data should be normalized. Will not work on the desktop
	 * @param stride the stride in bytes between successive attributes
	 * @param buffer the buffer containing the vertex attributes. */
