Method Details

computeLightingAt

protected abstract void computeLightingAt(BlockAndTintGetter level,
 BlockPos pos,
 BlockState state)

setup

public final void setup(BlockAndTintGetter level,
 BlockPos pos,
 BlockState state)

Set up this lighter to light quads of the given block.

Parameters:

level - the region containing this block

pos - the position of the block in the given region

state - the block state at this position

reset

public final void reset()

Invalidate and reset any cached state of this lighter.

computeLightingForQuad

public final void computeLightingForQuad(BakedQuad quad)

Compute the brightness and lightmap values for each vertex of this quad. After a call to this method, the values may be accessed using getComputedBrightness() and getComputedLightmap().

Parameters:

quad - the quad to compute lightmap values for

getComputedBrightness

public final float[] getComputedBrightness()

Returns the computed brightness for each vertex of this quad.

The returned array is only valid until this lighter is asked to light another quad.

getComputedLightmap

public final int[] getComputedLightmap()

Returns the computed lightmap for each vertex of this quad.

The returned array is only valid until this lighter is asked to light another quad.

process

public final void process(VertexConsumer consumer,
 PoseStack.Pose pose,
 BakedQuad quad,
 int overlay)

getColorFast

private float[] getColorFast(int tintIndex)

calculateShade

public static float calculateShade(float normalX,
 float normalY,
 float normalZ,
 boolean constantAmbientLight)
