I'm currently trying get my game to save data when I switch frames (Score count, the player position and if a enemy have been killed) and I've heard you guys say to achieve this by using Global Values and stings, But I can't find any tutorials explaining how they work, can you guys help me?
Basically Global Values & strings, is information that can be set/retrieved across any frame in your application.
So for example if you want to carry over a players position from one frame to the next:
(frame 1)+ Whatever event that changes the frame:
Set Global value A to PlayerX
Set Global value B to PlayerY
Next Frame
(frame 2)Start Of Frame:
Set playerX to Global Value A
Set PlayerY to Global Value B
If that makes sense?
EDIT: Heres a very basic example of what i posted:

For me it says that file is corrupted, I can't open it or extract it anywhere.

Don't know what happened there
I reuploaded it, try the original link and all should be good now.
Well that's what I'm mostly talking about, What I'm actually speaking of is this:
When you change frames the player's position or where it was created goes into a different area, say f I hav have an RPG and there's a mian and there are houses, each house )let's just now say that there is two) has a different frame, I can enter in the houses easily but when I exit them I end up back at my original position, I want it so that you reenter the main area frame your in a specific position.
Also how do I do this with a counter?
well, you could set a global variable - ie you enter a house on frame 1 then set global variable a to 1 and then goto frame 2.
Next, when you come out of the house on frame 2, change to the frame 1 (or whever the house door was) and do global variable a=1 position active 340 x 45 (position the character/active to the position outside the door).
Then change the global variable a back to 0.
You could also use ini files but could get a bit more complicated...
I see, But know I have another question (I was thinking of making a seperate thread for it but's it's a very similar question and that would be wasting space)
How would it be possible to transfer counter data across frames and so that every time it increased it stayed like that across frames.
i think you would want to make the counter a global object but i don't think counters support being global. (can't remember)
an alternative would be to use another object such as an array or a string$ object (an object that can be global) most also have alterable values which you could use to increment values, convert the string to value and +1/-1 etc.
array's i find much more useful for this stuff, i use them for saving positions of all objects, player data, information on objects, dialogues the list goes on.
hope this helps
update- - counters can be global (i checked), in the object properties you want to tick a box for "Global Object", another tip would be to rename the object and then drag it into the other frame from the older frame then the two objects will match up and keep the values across frames
More or less: Players score is 250, Player get's money in the first frame then the Player receives +50 and has 300, when the player enters the 2nd frame the player has 300 and if they come back to the first frame they still have 300.
The same as with the positionsQuote:

Store the counter value in a global value to carry it across frames, then on the next frame set the counter to the global value.
Or use the global values as your score/time whatever, and set the counter to display those values.
Also for the RPG, going into homes/shops.
Player leaves the shop:
Set global value A: (X Position you want player to appear on the next frame, eg outside of shop)
Set global value B: (Y Position you want player to appear on the next frame, eg outside of shop)
Start of frame:
Set Player X - global value A
Set Player Y - global value b
There are many ways this can be done, but this is just a simple example.
if i have time later ill do a quick example of entering/exiting shops, carrying scores over etc.
sorry heres a really quick mockup

The example doesn't remember what coins you destroyed, so when you come back out they're all there again. Just shows you how to carry scores over with global values and how to enter/exit rooms and appear outside them.
Though for the score method, doing what Zem mentioned would be better (setting counter to global object), i actually didn't realise you could do this!
I sorta figured out how to by simply making it so that when you earn gold it adds to the global value, but thanks anyway guys!
congrats :) i don't like using global values for things unless it relates to application wide values but whatever works for you :).
another way would be to set the counter to being global, using one of its internal alterable values and at the start of the next frame setting the counter to whichever internal alterable value was used in the other frame. the counters need to be named the same ie "Counter" etc and they will link between frames.
anyway good luck to you in your future endeavors :)
If I remember right the MMF core app did not work. You need to use an extension to get this to work. Take a look in the ExtensionView for an object to use on both frames like Global Store X. Then it will work. I ran into the same problem in the past.
I hope some day this issue will be fixed since this question comes up on the forum a lot by new users. There needs to be Global Area screen where global values are listed and made simple for the new user.
I use 2 global variables (counters) to save x and y values from the player. If you have a frame that is a menu for example you'd want to save your exact position because when you exit the menu and return to your previous frame you want the character to be in the spot you were when you entered the menu :)
