Jumping between frames "rooms" help

[frankodragon]

Using MMF2 Dev I'm trying to get the player to move to another frame then coming back to the original "room" without starting from the beginning of the frame using the jump to frame + X Y positions. When I jump from frame 1 to 2 for instance, that works. But jumping from frame 2 to 1 doesn't. Here's what I'm doing so far:


*Upon pressing "up" arrow
*"collision between "character" and "door"
-Jump to frame number 2+X( "character" )+80+Y( "character" )+350



*Upon pressing "up" arrow
*"collision between "character" and "door"
-Jump to frame number 1+X( "character" )+75+Y( "character" )+328

I must be doing something wrong in the second part.

Hmmm, you are trying to add apples to oranges

Your frame number is a number between 1 and the number of frames you have in your game.

X("character") is the x position (in pixels)from the left hand edge of the screen.

Y("character") is the y position (in pixels)from the top edge of the screen.

You need to save the state of the game when you jump from room to room. The easiest way to do this is with the new Save/Load frame actions.

However, these are not available in the demo version. Do you have build 246 of MMF2 Dev yet?

I dont understand all the extra stuff after "Jump to frame Number"'s purpose.

The way i've always handled this, is have a global value, say A.
I generally set the value of this prior to the start of the first level, and set it to 1. If it equals 1, set position to wherever the start of the level is.

If equals 2, then set position to wherever the other point you want to guy to be, and so on.
Make sure you run that set position event "Only when the event loops"
Then all you really have to do is change this global value whenever you enter or exit a door.

Suprisingly, i've never figured out how to actually use this function. If you could give a quick example of how to do it, you'd be my hero.

I would have thought the load save frame would load the old variables too so anything you did in the previous frame, getting pickups, would be lost. Is this not the case?

[Sarah]

Anything done in frame 2 would be 'forgotten' when loading the Saved Frame 1 file. But if you were just wandering into another room and back again, that wouldn't matter. You'd need an external ini or array file for pickups with this method.

"You'd need an external ini or array file for pickups with this method."

So this pertains to 1UPs as well?
