lol I'm a mmf2 noob!

Hey, smart people of MFGG-- I'm making a rpg-overworld type thing in mmf2, and I need to check which kinda terrain the character is on; I have 40+ terrain types, all of them are active objects. Is there a fast way to find out what object shares the same coordinates as the player without having to check for overlapping instances and/or collisions? I've noticed that if you have a lot of collision events coupled with a lot of objects it slows the game down considerably.

I've tried checking if the player's coordinates match the terrain object's coordinates, but that doesn't work when there are lots of duplicate objects, apparently.

help?

the best way to get this to work is to remember a couple of things:

1. use a many-to-one event; in other words, when dealing with object selection, there is a difference between X position of "lots_of_objects" = X("just_one_object") and X position of "just_one_object" = X("lots_of_objects"). you want to use the first one

2. don't use 'compare two general values' if you can avoid it; it jacks with object selection and you'll have to use fastloops

what you want to do is have an event like:

X position of "terrain_object" = X("player_object")
+ Y position of "terrain_object" = Y("player_object")
--> terrain_object: [do whatever]

you want to use Position -> compare x/y position for the terrain objects, and use X("Player_object") and Y("Player_object") in the expression box; needless to say i hope you have the hotspots for all the terrain objects in the upper left, because reliably getting offsets for this event can be a pain. you may also want to consider using x left("player_object") and y top("player_object") instead

it may help to have all of your terrain objects share a qualifier if they all need to do the same thing in this case

Whoa, never thought of doing that, thanks for the informative post, it helped a lot. And yeah, luckily I had the hot-spots set to the top-left, thank god. That would have been annoying to go through and edit every single image.
