i have disabled the battle engine for now...it's VERY messy codewise. improvements to the scrolling engine: the map is the right size, luigi renders properly, changed action button to Z, added foreground and collision map, you talk to luigi by walking up to him and pressing Z instead of just clicking on him, marios jumping animation no longer relies on a separate sprite. to be added: an action button for talking. being able to enter buildings. (the following places already have this feature: the green hut in the lower-right corner of the map) luigi being able to follow mario & switch places with him. (and then more characters that can be switched with luigi, like the party system from paper mario)
