mmm.newbie here.
i putted the controller in 1st room changed the values of the code.
in the create of controller i putted the 2nd code box.
in a begin step event the third code.
and in the objects of the room i putted in the create event set variable pausable 1
now the error i get....
ERROR in
action number 1
of Begin Step Event
for object musicontroler:

Error in code at line 13:
if ( pausable )
^
at position 39: Unknown variable pausable

why it doesnt see the variable pausable=1?
any idea?

From what I understand, the error seems to happen when your controller object checks the value of the "pausable" variable for all objects. So, the problem must be that the "pausable" variable is missing (or is misspelled) in the Create event of one of your objects. Did you double-check your objects to make sure that it's initialized properly in all of them?

A good way to avoid forgetting to include a variable shared by many objects is to use parenting: make a parent Pausable object that initializes the "pausable" variable in its Create event and then make all other objects derive from it. That way, you don't need to initialize it all your objects. Then, if the derived object has or needs a Create event, call event_inherited() to also execute the code from the parent Create event (otherwise it'd override the parent Create event).

i solved it thx

[Bloodleh]

Great idea, although I prefer more a simply freezing everything by while(1). Also creating a surface of everything (or something?) and then deactivating everything with the built-in function is more efficient.

[ZeplashStudios]

what bout this? works perfectly fine for me: still basic, but I'm sure with a screen refresh and so on you can animate a sprite:

if keyboard_check_pressed(ord("P"))
{
keyboard_clear(ord("P"))
pause = 1
while (pause = 1)
{
screen_refresh()
draw_set_color(c_black)
draw_text(room_width/2,room_height/2,"PAUSED")
if keyboard_check_pressed(ord("P"))
{
paused = 0;
exit;
}
sleep(30)
}
keyboard_clear(ord("P"));
}

'Sup pixeltao,

This idea is awesome, I've been looking for a way to pause my games WHILE being able to control the game by making menu's and animations etc. Just came across this. The GM7 file still works 100% in the current GM8.1, so I've copied the code and did everything step by step. The only thing I just can't seem to find is:

Where the hell did you define your "pause" variable?!?! I don't see it anywhere in the example either, although it works flawlessly
and as you can guess, I get an error saying this variable wasn't defined in my own game. As expected...

If you can get back on me, I'll finally be able to experience the almighty power of full-control in-game pausing MUHAHA... Right, a bit over the top..

But please help!

[HerpDerp]

Nevermind, found it! works 100% in my game now, can't thank you enough

I came across this error when I tried out that code:

I placed the variable within every object that was in game and followed yours steps precisely.

It's a bit hard to tell without more info on your code, but I suspect that this error happens because of how the new versions of Game Maker treats undefined variables vs. how old versions treated them.

So, to solve this, make sure that the "pausable" variable is set to 0 or 1 in the Create event of your Gameplay_UI object (depending on if you want this object to be paused). The "pausable" absolutely needs to be initialized to a value before you try to check it in your Step event (or in any other event).

[DariusSlayer]

Yea, I got those covered... I'm working with Studio right now, so there ought to be some differences.

I think I'll create a Pause Controller instead of putting the function with the Gameplay_UI controller (which draws lives, score, and HP).

[Tarik]

A few comments from a few years back pointed out some of the difficulties in using this system. For example, using timers and various variables that aren't covered. (for example, I usually use a custom movement system that doesn't necessarily use gravity, speed etc, and creating unique holder variables for all the variables in the tens of datastructures I use isn't very practical.

Some also pointed out the option to use surfaces, or creating a sprite from the screen. But others pointed out surfaces don't work for everyone (I have to say though, this was mostly an issue in 2008 when a lot of people were still using old cards), and that not everyone can create screen-sized textures. (again, an old card issue, cards can normally always create a texture the size of the screen/resolution.)

If you still don't want to create new textures or surfaces, if you use pre-studio GM, I think all you'd need to do on pauze is to set automatic drawing off, change room to a pauze room, and then call screen refresh in the room and draw ontop any pauze message you'd like. On any keyboard input you'd switch automatic drawing back on and change the room back. Should be a few lines of code, all it requires is a persistent room. If you don't want that, just call room restart when you need to, and set it to persistent anyway.

Yea, now all I get is this for a warning:

So, I did something right, I guess, that got rid of the other line of code causing an issue... I'm looking it over again and again but I really don't see how this error can come up :/

Do you know if it's possible to open a GM Studio file with Game Maker 8.1? If that's the case, you could send me your project. It'd be easier to help you figure this out.

[DariusSlayer]

Don't know if that's possible, but yea, I can try. PM me your emaill address, or if you want, we can text over Skype.

[DariusSlayer]

As of now, I have an inventory box that appears when the game should pause.

[rjj95]

{
draw_set_font(font_pause);
draw_set_color(c_red);
draw_set_halign(fa_center);
draw_text(room_width/2,100, 'Game Paused. Press any key to continue');
screen_refresh();
keyboard_wait();
io_clear();
}

problem solved.

[pixeltao]

@DariusSlayer: After some investigation, I believe that this error is caused by the fact that GM Studio doesn't set a default value to uninitialized variables. In this case, the pause variable is declared but never initialized to a value. To fix this, you have to add:

pause = 0;

In the Create event of the Controller after the pause global variable is declared. I edited the first post to include this modification.

@rjj95: Not really. Please read the first post before posting comments.

[DariusSlayer]

WHen this code is in the Step Event (as it should be), "if ( pause ) exit;", all objects that can fire can not and my player can not move. When I remove this code, every one of those object function normally, but I can't pause... I've been starring at the main code for a while now and still can't figure it out. The function of the pause works. It really does and I'm glad that it does, but baffled as to why it's impeding the other functions.

When I put it in my object's Step event and try running my game to see it work, I get this message:

___________________________________________
COMPILATION ERROR in Script: pause

How can I fix this?

Did you follow exact the implementation explained in the 1st post? Because, if you put the pause code into a script, or make some changes to it, it might not work as intended.
