I have a grid-based or tile-based movement system that can move a selected character up to their movement range away from their current tile. This works perfectly fine for flat surfaces where there are no obstructions, but as soon as I add obstacles to the map, the characters can completely ignore them and phase right through without account for their movement range (e.g. rather than needing to walk past a wall, they can phase right through).
What I want is a way to calculate which tiles they can move to with respect to any obstacles in their path. I have no idea how to achieve this, and can’t find any resources. Here’s a dumbed down rblx file since I know this is kind of complicated to solve without getting hands on

This function is from a script that is a localscript in StarterPlayerScripts that controls everything related to mouse controls. The function checks every block to see if it is within movement range, and if the tile is within movement range and not an obstacle, teammate, or enemy, the function marks the tile as being able to move to.
