Collection of RPG_RT bugs for compatibility

[mateofio]

There are various RPG_RT bugs out there which may be depended on by different games. I've created this issue to catalog them. At some point we may want to enable a compatibility mode switch for some of these bugs if we find games need them.

Please list your known RPG_RT bugs here:

• Break statements in nested loops don't obey scope. They always jump to the next EndLoop. BreakLoop is correct in Player but broken in RPG_RT #1442
• Medicine usability is ignored in rm2k3 battles. Fix Item usability in battle - Previously Albeleon 2.30 #1482
• Panorama data is not saved in rm2k. Support SavePanorama data #1485
• Panorama data is not cleared when map save_count doesn't match LSD. Support SavePanorama data #1485
• If you save while the screen is panning it won't continue when you load.

I have a huge list.

Maybe I should do what I wanted to do a while ago while discussing how to approach any possible future fixes: Open a GitHub repo for RM2k(3) but for issues only, similar to https://github.com/Microsoft/wsl

Thing is just that it's a huge amount of work.

Flash saturation and Flash period (?) are not saved in the savegame.

Player/src/game_screen.h

Line 101 in 1d5aedc

int flash_sat; // RPGMaker bug: this isn't saved

In ShowPicture (2k only): When ShowPicture has no effect, then effects of MovePicture are ignored:

Player/src/game_picture.cpp

Line 181 in 1d5aedc

// Possibly a bug(?) in RM2k: if Show Picture command has no

The "Moving into an event triggers it's interpreter (for the "move away feature")" results in "Waits" to finish faster (twice as fast when one event/player runs into it, three times when 2 and so on):

Player/src/game_event.cpp

Line 733 in 7d43de4

// Placed after the interpreter update because multiple updates per frame are allowed.

Some japanese games use "-1" (which is the ID of the party when not in a Vehicle) as the target vehicle for "SetVehicle" which allows moving the party around (even across maps!) without triggering a transition. We don't fully emulate this (a normal teleport is executed):

Player/src/game_interpreter.cpp

Line 1662 in 4c589a4

// SetVehicleLocation moves the party, too, when she is in the referenced

We emulate all these bugs because this really breaks games when you don't do it!

iirc the "Target select" window in the game menu (where you select a party member to use a item/skill on in the menu) ignores the "Half SP cost" attribute and shows the full SP cost but when executing the value is correct (halved).

Flash saturation and Flash period (?) are not saved in the savegame.
Player/src/game_screen.h

Are you sure? It should be saved as SaveScreen.flash_current_level and SaveScreen.flash_time_left

[Ghabry]

Are you sure

No Im not, just did a code search.

This bug here: #1391
Negative E values which allows "enemy attacks can heal" is broken across all RPG Maker versions. (the expected behaviour is mentioned in the help file :))

The easyrpg variables he refers to are for continuous flashing. You need copies of these 2 fields to tell the flasher how to repeat the flash. #1501

Rm2k3 doesn't let you put all party members in the back using the Row command. At least 1 member must be in the front.

However, if you put some party members in the back row and then remove the front row members, you'll end up with a party with everyone in the back.

All items that trigger skills use the source of the skill to the highest level member of the party (first one if same level).

That means that items that trigger skills that have usage == self will always be used on the highest level character in the party.

Not sure if this is really a bug:

If an actor has an "Attack All" weapon and gets confused or provoked, he will only attack one ally or enemy.

[mateofio]

Create a skill with:

• Heals Death
• 0 power, phys, mag, var

Use it on a dead actor in battle in 2k3,

The actor will revive with 1hp, but the displayed green number will say -1 ❗

Set a move route on the player which changes the player graphic. Then save and load the game.

Upon loading the hero graphic is reset.

Here's a bug I observed a while back around panning and player movement.

tldr: Panning the map away from the player, then moving the player into that new camera frame, causes the camera to become offset until the player returns to the tile they were originally on.

Though frankly I doubt there's any game that makes use of this behaviour to necessitate replicating it.
