On Destroyed Bug after Loading Game State[gamebreaking bug!]

  • Problem Description

    When an instance is destroyed, and then the game state is saved, loading triggers On Destroy to misfire after the page is reloaded or newly run.

    edit: btw, if you have multiple on destroy events, you can have multiple misfired events depending on how many destroyed instances there were when you saved.

  • Here is more information I discovered while trying to find a work around.

    I used a global variable and set it to 1 before loading. Then on destroy events, I add condition to check if variable is 0.

    It seems the On Destroy fires BEFORE loading (when everything is destroyed), and the resulting actions in that event are performed AFTER loading.

  • Well, this is currently by design. If you load a savegame with fewer instances, the additional instances are destroyed. Destroying instances triggers 'On destroyed'. I guess we could change this though to skip those triggers.

  • I don't really see any reason why anyone would want the triggers to fire when loading a savegame- especially when it results in a game state that was different than when it was saved.
