Checking and unchecking custom menu bar items

[Shawn]

I'm having a problem that I can't solve for the life of me. I made a custom menu item in the menu bar editor. It is checked by default. I have my events set up to check and uncheck the item but it will not uncheck it. Here is what my events look like:

The strange part is if I swap event line 29 with event line 30 it will let you uncheck the item, but then you can't check it back when you go select it again. The only thing I can figure is that there is a problem with it running all of those events at once since the menu selection is a red event. It also doesn't make a difference if I switch the order of the conditions so that "menu option selected" is on the bottom. I don't see anything else in the event editor that would let me overcome that issue in the menu bar events. Apparently I'm not grasping how those events work.

I could maybe overcome this if I have two menu items, "Show Grid" and "Hide Grid" and have them check and uncheck one another, but I don't want to do it that way.

Well I managed to fix it with a workaround. I used a global value and every time you select the menu item "Show Grid" it adds 1 to the global. Global A = 1: uncheck. Global A = 2: check set global A to 0.

Soooo it works. But seems like a really cumbersome and silly way to do that. Surely there is a better way?

Your original events suffered from the "If A set B, If B set A" situation, in which it will always be A. The reason is because both events run; first it sees that it is checked, and thus unchecks it. The next event then sees that it is unchecked, and checks it. This is not a toggle, this is a problem caused by lack of an else statement in MMF2.
For your solution, would it not be easier to just set Global A to 1-Global A? Evey time you do this it toggles between 0 and 1

Yeah that's what I assumed was happening with the original events. I know the red conditions run immediately and were doing as you say.

And yeah, lol it would probably be easier to do what you suggested for the globals.

Actually I thought about it, and the outcome would be the same whether they were those red immediate conditions or not. Don't know why I thought that would matter because either way the events would be running together.
