One of the popular algorithm for pathfinding is A*, but A* still has problem about its memory usage. Iterative Deepening A* (IDA*) is an algorithm like A* that uses Depth First Search to prevent the large memory usage. This research develops a game that implements pathfinding method to enemy character using A* and IDA* algorithms to compare their memory and time usages for pathfinding. Heuristic function that used is Manhattan Distance. This research uses 3 different types of map (without obstacle, simple obstacle, and complex obstacle) with 3 different samples in each type of map as tool for comparing the memory and time usage by A* and IDA*. The conclusion of this research are memory and time usage for A* and IDA* is affected by the size of map (node quantity), position of the obstacles on map, and the obstacle quantity. Then, IDA* Algorithm is generally better than A* in case of memory and time usage especially if the map doesn?t have any obstacle, but IDA* can be worse if the enemy character and player are at the parallel position that covered by obstacle} }
