In the last blog I switched from a grid-based movement system to a system that allows the player to move in any direction.
Additionally, I’ve stopped using a GridMap for build my levels and instead am now using the Quake map format.
Unfortunately this means that the pathfinding system using AStar I built before is no longer valid.
In contrast though, I can now use Navigation nodes for pathfinding without doing too much work myself.
Implementation
Qodot generates collision meshes for us, this means that if we simply move the QodotMap to be a child of NavigationMeshInstance we can automatically generate the NavMesh from the level.
From there I retrofitted the script from my previous implementation so that monster would follow an array of points to their target. For now updating the target every frame doesn’t appear to be a problem with small amount of monsters.
