It's the PluginCommonBase, which might be on \RPG Maker MZ\dlc\BasicResources\plugins\official (more on this thread MZ - PluginCommonBase? | RPG Maker Forums)
Let me know if you can't find it.
Viewing post in Live Menu and Pause MV + MZ comments
I gave it a try and didn’t notice any glaring issues as-is: The battlers seem to appear correctly behind the menu and the battle didn’t proceed until the menu was closed. The battle also didn’t restart, as far as I could tell.
The battler sprites flicker for one frame when entering or exiting the menu. I think this is a general issue with Scene_Battle, as I can see it even without Live Menu enabled when exiting the custom menu (if I slow down the frame rate to make it more noticeable).
I’ll see if I can make the Scene_Battle load the current battler sprites once right when it starts, which in theory should fix this in general. That could cause a slight (likely unnoticeable) delay when entering battle otherwise, though, so I’ll make it optional.
You should otherwise be able to use the plugins together without issue already, but do let me know if you notice anything else!
You mean images displayed through “Show Picture”, right? I suspect the problem there may be that a different set of slots is used while the Party is in battle.
These should be displayed as normal within the Scene_Battle running in the background of the menu.
There could be unintended effects if SceneCustomMenu tries to display them too though, like animations being twice as fast.
The issue I had months ago was before knowing your problem. I used a script to load images inside the choices of menu, and I set a small code to change it in real-time, replacing the icon on current choice for a yellow highlighted one. It bugged until every images until I preloaded them. And it had different results every time I opened the menu.
Correcting my affirmation, it seems more a problem when dealing with images changing inside menus, and with images while transitioning from scene to scene. I'm no scripter by no means, but as you said, I assume preloading these images could fix it?
For the currenting issue regarding Live Menu and SceneCustomMenu, what I noticed is the whole screen flashes after I close the menu. I tried now a preload for battle assets (DKTools), with no success. Does you screen flashes this way too?
I didn’t test with battle background image yet.
(Using the blurred map as background image in battle is managed a bit differently.)
I’ll try this in a few hours, since it’s currently still night here.
Loading the images right as the scene is created should fix it (in theory), as that should normally make SceneManager wait until assets are loaded.
I uploaded a release-candidate version that should be able to fix the flickering issue.
(It’s fine to use this in production, but there’s a possibility I may revise the added feature in a way that requires manual adjustment.)
If you turn on the new “Prevent Battle Flickers?” parameter, this should now prevent screen flickers and flashes. It’s off by default because there could in theory be unintended side-effects.
One caveat that I noticed is that the Actor stance seems to revert to the idle pose while the menu is open (when doing so from a turn-based Troop Page). I’m not sure if that’s intended behaviour that always happens when a blocking Page runs, or if there’s still an unresolved glitch.
