So I've been trying to plan out a turn-based strategy game, and was thinking about unit movement, with suggestion options to a player and to handle a computer player's choices. I was thinking of using a simple A* method to find the shortest route to the desired space. Since a space can be advantageous or problematic, would just adding an extra variable to the heuristic help in avoiding certain regions and moving towards others? For example, assuming a unit can move say 10 spaces a turn, and units could potentially be hiding in specific terrain, a unit would want to walk around the terrain a unit can hide in (like woods), so they don't run into a dangerous space. Would just rating the movement cost higher for that space be enough?
