Package codechicken.lib.render.shader

Class ShaderProgram

java.lang.Object

codechicken.lib.render.shader.ShaderProgram

All Implemented Interfaces:

net.minecraft.server.packs.resources.PreparableReloadListener, net.minecraft.server.packs.resources.ResourceManagerReloadListener

public class ShaderProgram
extends Object
implements net.minecraft.server.packs.resources.ResourceManagerReloadListener

A ShaderProgram.

As of 1.18.2, you will probably want to use CCShaderInstance instead as an extension to Vanilla's ShaderInstance.

You probably want ShaderProgramBuilder to construct a ShaderProgram. it should be noted, that a ShaderProgram is a ResourceManagerReloadListener, its recommended that you ensure this is registered to ReloadableResourceManager to ensure ShaderObjects are re loaded properly when Resources are reloaded.

Method Details

getShaders

public List<ShaderObject> getShaders()

Gets all ShaderObjects that make up this ShaderProgram.

Returns:

The ShaderObjects.

getUniforms

public Map<String,CCUniform> getUniforms()

Get all UniformPairs exposed by this shader.

Returns:

The uniforms.

getUniform

@Nullable
public @Nullable CCUniform getUniform(String name)

Get a CCUniform from this ShaderProgram.

Parameters:

name - The name of the Uniform.

Returns:

the CCUniform.

getProgramId

public int getProgramId()

Gets the GL ShaderProgram id for this shader. Might not be initialized until use() is called once.

Returns:

The id, -1 if not initialized.

use

public void use()

Binds this shader for use, Lazily allocates, links and compiles all ShaderObjects.

compile

public void compile()

Forces the ShaderProgram to compile and link.

This will happen automatically when calling use(), however, it may be required to call this ahead of time in some cases.

Be sure to only call this when you have GL context.

release

public void release()

Releases this shader.

onResourceManagerReload

public void onResourceManagerReload(net.minecraft.server.packs.resources.ResourceManager resourceManager)

Specified by:
