[Monoliths Mario World] A single fall kills Mario forever.

[Jmousy]

Expected behavior

After Mario dies, the stage should restart after the game over screen appears.

Is the problem with the Ruffle desktop app, extension, or self-hosted version?

Tested on self-hosted & Desktop.

What platform are you using?

• OS: Windows 10 21H1 x64
• Browser: Chrome Latest
• Ruffle: 2021-09-11 Nightly

Thank you for filling an issue. I have investigated it using JPEXS.

When Mario falls off the screen (actually hits an invisible object), the following code is triggered:

if(_root.player.hitTest(this))
{
   _root.die(true);
}

located in \DefineSprite (118: abyss)\frame 2\DoAction.

Here's a part of the function die:

attachMovie("player_die","player_die",2001);
player_die._x = px;
player_die._y = py;
trace(player); // added for debugging
removeMovieClip(player);
trace(player); // added for debugging
power = 1;
have_star = false;
lifes--;
container("empty");

located in \frame 3\DoAction.

The above calls to trace logs the following messages:

• in Flash: "_level0.player" and an empty string.
• in Ruffle: "_level0.player" twice.

Because of this, Ruffle kinda gets stuck in a loop.

This issue is probably related to #4404, #3839 or #993.
