I am making a game where the player gets chased by lava along a road.
From the road mesh i can access the points along each side. Currently i have an edge collider that moves along these points and once it reaches the player it's game over.
My problem is that i can't figure out how to make the lava follow the edge collider. Any ideas? I am using Unity.
Depending wether your game is 2D or 3D, there are different ways to go with this problem.
Supposing it is top-down and the lava is a sprite, maybe you can get around this issue by masking your lava with a Sprite mask : - https://docs.unity3d.com/Manual/class-SpriteMask.html
If you move your mask along with your edge collider, this should do the trick.
If your lava is a 3D object, you can add a cutout shader to it, and manipulate the "cutoff" value and settings to animate it following your edge position.
You could maybe voxelize lava part of the map and form a grid. From there just use dijkstra path finding and turn it into a grid crawler. Every node on the grid is either lava or transparent. Check every frame if nodes occupied by a player are lava. Visualization of dijkstra algorithm.
