Changing variables based off rooms

[BladeGamez]

I have a space level that I want to include in my game. Do I simply make my variables global and go into my room and subtract and add to the variable at will? For example, in the space level I want to decrease the jump speed.

Directly input the variable in the room creation code

or...

Use a persistent controller object with a room start event to read the room and set the values accordingly (probably the best way so it's all in once place.

that sounds about right, yes

but what I would do instead if you only have one player object:
add a "other->room start" event to the player object and let it check the room type

if(room_get_name(room) == "name of your space level room"){
 jump_speed = [your desired jump speed]
}else{
 jump_speed = [your default jump speed]
}

this code will check one time only what jump speed to set for the room and if it is your space level will set the jump speed for space
in all other rooms it will set the jump speed to your default jump speed

this way you won't forget to "reset" your jump speed when you are not in space anymore (which can happen if you use global variables)
