I'm working on a particle design program, and to change a direction setting for particles i wanted to make a circle track with a knob in it, and you click and drag the knob to change the direction, while the knob is still confined to the track.

my current method is to make a circular path, and then use the distance along it as the variable, but i was hoping to find a more practical method. any suggestions?

I was thinking of a method to animate a 3d texture, because sprites just DONT WORK. my idea was to take a sprite and get the current frame and then swap out a background with that frame, and then use the background as a texture. do you think this would work?

Hi! I was wondering what sot of method I would use to create a minecraft-like 3x3 'crafting grid'. basically the concept is whee you take items and then arrange them in a patten to get a new item. thanks in advanced 8D

NEVERMIND
PROGRAMMER ALREADY GOTTEN

Hey!!!
I am a Newb, so if there is something already on this subject, please tell
I set up a system of realistic doors (eg, when you enter a door, it takes you to a room, but loads you in a different spot based on which door you used.)
right now it is extremely primitive and needs a lot of work, as each door needs to be a sepparate object and have it's own collision event. if there is already a script for this, please point me to it , or if there isn't, could i have some advice/help to make this system more dynamic/easier to use?
how it works:
1) set collision w/ "door" to change to room and set the coordinates (a global var)
2) put in a create event that makes it jump to the global var coords.
this may need a total overhaul.
an example is NOT included, but will be supplied if asked for.
Please help.
