@ -188,6 +188,7 @@ Nazara Engine:
- Fixed TextSprite not handling multiple textures well
- ⚠ TextSprite will now use multiple render layers by itself (the current one and the one right before, ex: [-1, 0] if base layer is 0) if you use text outlines.
- ⚠ SimpleTextDrawer no longer supports faux bold rendering
- Added PhysWorld2D::[RaycastQuery, RegionQuery] overloads taking a callback
Nazara Development Kit:
- Added ImageWidget (#139)
@ -263,6 +264,7 @@ Nazara Development Kit:
- Added CollisionComponent2D::SetGeomOffset and CollisionComponent2D::Recenter
- Added LifetimeComponent and LifetimeSystem
- Fixed a subtle bug regarding entities invalidation and kill (ex: if an entity #2 kills entity #1 during Entity::Destroy callbacks, entity #1 will survive destruction).
- Added PhysicsSystem2D::[RaycastQuery, RegionQuery] overloads taking a callback
