(built off the vanilla `AffineTransformation`) - * But this means... when i'm building the "left" side of the slope, what side of the block should i look at? I have to undo this affine transformation +* More templates !! ## Notes for addon developers diff --git a/src/main/java/io/github/cottonmc/templates/model/TemplateBakedModel.java b/src/main/java/io/github/cottonmc/templates/model/TemplateBakedModel.java index bbb7dc3..9ff3a4c 100644 --- a/src/main/java/io/github/cottonmc/templates/model/TemplateBakedModel.java +++ b/src/main/java/io/github/cottonmc/templates/model/TemplateBakedModel.java @@ -22,6 +22,8 @@ import net.minecraft.util.math.random.Random; import net.minecraft.world.BlockRenderView; import org.jetbrains.annotations.NotNull; +import java.util.EnumMap; +import java.util.Map; import java.util.function.Supplier; public final class TemplateBakedModel extends ForwardingBakedModel { @@ -31,12 +33,28 @@ public final class TemplateBakedModel extends ForwardingBakedModel { this.tam = tam; this.affineTransformer = new AffineQuadTransformer(aff); this.baseMesh = baseMesh; + + //Hard to explain what this is for... + //Basically, the previous incarnation of this mod assembled the north/south/east/west faces all individually. + //This means it was easy to get the orientation of the block correct - to popular the north face of the slope, look at + //the north texture of the theme block.
