From 68daac86593eaec15f3cd787f17f75b78b90c010 Mon Sep 17 00:00:00 2001 From: Jozufozu Date: Wed, 21 Feb 2024 12:37:46 -0600 Subject: [PATCH] Debugging broken overlay/lighting - Break instance overlay/light back into 2 layout elements - Write light directly as an int - Make light a short backed float element - Clamp overlay coords in common.frag to avoid explosions - Explosions: integer vertex attributes sometimes blow up to massive sizes, greater than Short.MAX_VALUE which should not be possible. - Reorganize some texture/uniform binding code --- .../jozufozu/flywheel/backend/InternalVertex.java | 4 ++-- .../jozufozu/flywheel/backend/engine/MeshPool.java | 13 +++++++------ .../backend/engine/instancing/InstancingEngine.java | 2 +- .../backend/engine/textures/TextureBinder.java | 9 +++++---- .../flywheel/lib/instance/InstanceTypes.java | 12 ++++++------ .../assets/flywheel/flywheel/instance/oriented.vert | 4 ++-- .../flywheel/flywheel/instance/transformed.vert | 4 ++-- .../assets/flywheel/flywheel/internal/common.frag | 9 ++++++++- 8 files changed, 33 insertions(+), 24 deletions(-) diff --git a/src/main/java/com/jozufozu/flywheel/backend/InternalVertex.java b/src/main/java/com/jozufozu/flywheel/backend/InternalVertex.java index f95e9d431..1eb861140 100644 --- a/src/main/java/com/jozufozu/flywheel/backend/InternalVertex.java +++ b/src/main/java/com/jozufozu/flywheel/backend/InternalVertex.java @@ -4,9 +4,9 @@ import java.util.List;
