Libgdx no usa OpenGL ES 2.0

Question

Preferiblemente, me gustaría usar OpenGL ES 2.0 para un nuevo juego en 3D comencé a hacer.De todos modos, lo he estado desarrollando en una PC de Ubuntu (no de primera línea pero decente) que compré en 2010.

gdx.graphics.isgl20Available () devuelve False, y estoy bastante seguro de que mis conductores admiten 3.3.0.Aquí está lo que estoy recibiendo de GlxInfo:

y mucho más que no tiene que ver con la cadena de versiones y / o extensiones.Tengo todas las extensiones necesarias para OpenGL ES 2.0 y mi controlador se actualiza a 3.3.0 (OpenGL 3.0-> 2.0 ES aproximadamente).¿Es porque mi rasterizador de software es viejo?Si es así, probablemente hay otros en la misma situación (ni siquiera creo que haya tantas instalaciones de Windows que se actualizan más de 1.1), y también me gustaría apoyarlos.¿Cuál es la mejor solución posible?

Answer 1

gdx.graphics.isgl20aveable () no le dice que su hardware admite GL ES 2.0.Le dice que se ha inicializado el contexto gráfico GL20.

Debe solicitar a LibGDX para usar explícitamente GL20.Ejemplo para el backend lwjgl:

LwjglApplicationConfiguration config = new LwjglApplicationConfiguration();
config.title = "Game";
config.width = 800;
config.height = 480;
config.useGL20 = true; //this is important
new LwjglApplication(new YourGame(), config);
