==================

• Fixed issue where raycasting with more complex collision groups was not working as expected
• Added new feature to collision group raycasting, directly provide a collisionMask that you want to search for. Theoretically this is less confusing

const playerGroup = ex.CollisionGroupManager.create('playerGroup');
const notPlayersMask = ~playersGroup.category;
const hits = engine.currentScene.physics.rayCast(
  new ex.Ray(player.pos, playerDir),
  {
    maxDistance: playerSightDistance,
    // Search for all categories that match the mask
    collisionMask: notPlayers,
    searchAllColliders: false
  });
