I have been trying to make a turn based game with out a grid. My original plan was to just use the navmesh since it was already built in but it has a couple issues. Navmesh is only an approximation and has no function to show the distance a unit can move from its current location. At best I have managed to just have it draw a spline to the cursor to display the one path that is found. My other option right now is a grid with very small tiles and units taking up multiple tiles.
So I am looking for alternatives to writing an entirely new path finding system which I don’t think I have the knowledge to do.
