In this example:
Color
is 0x00001000
.5
.Because the most significant bit is not set, the accessor macros that fall back to defaults don’t access unity_DOTSInstanceData
. This means that:
c0
will contain the value from unity_DOTSInstanceData
address 0x1000
.c1
will contain the value of the regular material property Color, and cause a compile error if the Color property doesn’t exist.c2
will contain (1, 2, 3, 4)
because that was passed as the explicit default value.void ExampleConstant()
{
// rawMetadataValue will contain 0x00001000
uint rawMetadataValue = UNITY_DOTS_INSTANCED_METADATA_NAME(float4, Color);
float4 c0 = UNITY_ACCESS_DOTS_INSTANCED_PROP(float4, Color);
float4 c1 = UNITY_ACCESS_DOTS_INSTANCED_PROP_WITH_DEFAULT(float4, Color);
float4 c2 = UNITY_ACCESS_DOTS_INSTANCED_PROP_WITH_CUSTOM_DEFAULT(float4, Color, float4(1, 2, 3, 4));
