Class Skyboxes

java.lang.Object
net.ixdarklord.coolcatcanvas.api.client.sky.Skyboxes
public final class Skyboxes extends Object
Custom skies: images wrapped around the sky (cubemaps and panoramas), images placed in it (sprites), gradients and shaders, each able to rotate, animate frame by frame and fade by time of day, weather or code; and parts of vanilla's sky hidden while they show.

Register skyboxes once, from client code (a ClientModConstructor is a good place): 


 Skybox bloodMoon = Skyboxes.register(MyMod.id("blood_moon"), SkyboxDefinition.builder()
         .hide(VanillaSky.MOON)
         .layer(SkyLayerDefinition.gradient(0xFF300000, 0xFF801010, 0xFF100000, 2.0F).blend(SkyBlend.MULTIPLY))
         .layer(SkyLayerDefinition.sprite(MyMod.id("textures/sky/red_moon.png"), 25.0F)
                 .name("moon")
                 .rotation(SkyLayerDefinition.Rotation.withMoon())
                 .stage(SkyLayerStage.ABOVE_CELESTIALS))
         .build())
         .fade(100)
         .activeWhen(context -> context.inWorld() && context.isNight() && BloodMoon.isActive(context.level()));
Resource packs can add skyboxes without code, in assets/<namespace>/skybox/<path>.json with a list of dimensions; see SkyboxDefinition. The server can drive registered skyboxes through SkyboxControl.

Cost: a skybox that isn't visible costs nothing. A visible one draws each visible layer with one draw call, from shared static meshes, with no allocation per frame.

    • register

      public static Skybox register(net.minecraft.resources.ResourceLocation id, SkyboxDefinition definition)

      Throws:
      IllegalArgumentException - if the id is taken by another registered skybox

    • register

      public static Skybox register(net.minecraft.resources.ResourceLocation id, net.minecraft.resources.ResourceLocation definition)
      Registers a skybox loaded from assets/<namespace>/skybox/<path>.json. It's loaded with the game's resources, and reloaded with them.
      Throws:
      IllegalArgumentException - if the id is taken by another registered skybox

    • get

      public static Optional<Skybox> get(net.minecraft.resources.ResourceLocation id)
      A registered skybox, or one a resource pack added (once resources have loaded).

    • all

      public static Collection<Skybox> all()

    • unregister

      public static boolean unregister(net.minecraft.resources.ResourceLocation id)
      Removes a skybox and frees what it holds.

    • disableAllInstantly

      public static void disableAllInstantly()
      Hides every skybox at once, back to vanilla's sky.
