  • It was, most PlayerFamily objects are not swimming, and I actually never tested the issue with one that was swimming.

    IsSwim is just a boolean that gets set the moment a player enters water, and then it gets updated to false when the player leaves the water.

  • Storing the local UID and referring to it again after the Function.ReturnValue did the trick, thanks for suggesting that. I had tried using that method previously, but I think I was a little hasty in dismissing it and placed the "Set LocalUID" action in the wrong spot, or needed to use the "Pick All" event as well, in any case it's working properly now:

    Why this is the only time this function has failed to produce results is beyond me, if it happens again I might pursue it further but given how many skills I've successfully implemented until now with it, I think I'll leave it be.

  • Skills aren't tracked through instance variables, there are far too many of them to do that.

    The PlayerSkillSetup function scans an array that is populated with the collected skills of the player(s) for the requested skill. If the skill exists in the players Y rows (each player has their own X row) then the function returns the "skillExists".

    This system has worked fine for the previous 40+ skills I have setup this way, hence why I haven't bothered sharing the PlayerSkillSetup function since it's never given me these issues with those previous setups.

  • try to insert a browser log of the UID in between each of those actions and see which one is interfering?

    This was a good idea, but gives me... bizarre results.

    If I set it up like this, where the browser alert comes after everything else and I disable the ValueText object spawn, it returns the correct UID:

    However, it fails to actually update the players variables. Their HP remains the same (double checked in the debugger to be sure).

    Enabling the ValueText object spawn causes the browser alert to once again return 0.

  • This is Construct 3, but it is built on a project that was originally started in Construct 2, and had far too many old Functions for me to feel comfortable updating them to the new Function system. I've continued to use the old function system as a result.

    What UID is it showing in the browser logging?

    This is the frustrating part of this issue. If disable the actions that update the players health and spawn the text object, the browser alert returns the correct UID:

    However, the moment I toggle those actions back on, the Browser alert returns a UID of 0.

  • I have a function I run to check if the player has a skill when it would be triggered. This has worked perfectly fine for the implementation of 40+ other skills, but this one time it just refuses to work properly. In this case, the skill is supposed to heal the player slightly when the conditions are met to pick up a coin:

    So as you can see, "PlayerSkillSetup" is ran, and if the player has the skill it is checking for ("skill_greed1") the Function.ReturnValue should equal "skillExists", at which point it runs the highlighted code.

    And it does run that code, but on nothing. Because despite passing the PlayerFamily.UID through the "PlayerSkillSetup" function and verifying it is picking the correct instance, the highlighted code runs on nothing. It spawns the ValueText object at 0,0, so it is running.

    I have tried a dozen different work arounds on this thing to no avail, and I cannot see what very well may be an obvious issue, help would be greatly appreciated!

  • That could be, the AI accepts instruction mostly from one source (a general "AIUpdate" Function) but does occasionally have to get instruction outside of that routine, which might be the culprit. Glancing through my events I don't see any that should be updating the animation externally, but that doesn't mean its not there.

    I'll keep that in mind if this rears its head again, for now the force "Start Animation" is working with no consequences.

  • lionz sorry, I should clarify, this is in regards to the current animations "Is Playing" value, specifically the one the debugger displays when inspecting the instance in question:

    My understanding is that the debugger value is always updating to the current animation in real time, that is what it appears to be doing at least, and while "Is Playing" remains true most of the time, randomly it does turn false when switching to the attack animation.

    Bandaid Solution in case anyone has this same issue in the future

    While I have no clue what is setting this value to false and stopping my animation from playing, I was able to "fix" the problem by putting a "Start Animation from Current Frame" action after the "Set Animation" action.

    To be clear, this shouldn't be necessary. The existing code works 95% of the time, but after adding this "Start Animation" action and running the game at 10x speed for an hour with an AI controlled enemy attacking a dummy, I haven't seen the issue pop back up. The debugger still shows the "Is Playing" value being set to false randomly, but this bandaid bypasses that.

  • I have this long standing, very random bug in my game I am trying to pinpoint with no luck.

    The short version is that when an enemy switches to their attack animation, very occasionally their animation freezes. Through the debugger I discovered this happens because SOMETHING is setting "Is Playing" to False.

    But here's the thing, to my knowledge the only action that can do that is "Stop Animation", and I do not use that action anywhere for any object (including these enemies) in my project.

    Searching the entire project for "stop animation" only gives me results for some disabled code I kept around for reference.

    Is there something else that can manipulate "Is Playing" that I am not aware of? Anything that might help me here would be greatly appreciated, this bug has been sitting there, randomly occuring, for months now.

  • This is pretty easy to test, just use the Advanced Random behavior to update the seed, then save (either using the debug save option or the plugin) close the game, then load the save.

    If you look in the debugger, the PRNG Seed is no longer whatever you updated it to be using Advanced Random. This of course ends up affecting everything that is tied to random generation.

    Now, I could get around this pretty easily by just updating the seed again after a load, but previously I didn't need to do this, and I am worried it could create issues if you save/load at just the wrong time. Am I actually just missing something and this is always how it worked and I've broken something elsewhere?

  • I've got a top-down layout that uses seed generation and a tilemap to infinitely generate terrain. Whenever the player reaches an invisible edge of the layout, their position is reset and the tilemap is repopulated with their new offset co-ordinates.

    Terrain cannot be modified by the player, so I don't store any of the terrain information in an array or anything.

    I do want to include "fog of war" (FoW) though, hiding undiscovered tiles until the player gets close enough to them.

    I can't simply place a FoW layer that erases tiles the player gets near because the entire layout is being re-generated constantly. Instead I need to store the offset positions of cleared tiles, and I'm curious what is the most efficient way of doing this? I could make an array and place in every tiles offset X and Y, but that array will quickly get massive as its expected the player will be uncovering tens of thousands (if not more) tiles during their exploration.

    Suggestions? Thanks!

  • I'm building an NES/GBC style game, so it uses spritefonts. Currently, I am building all the menu/UI/dialog text to pull from a language array, where it simply pulls using a key word. For example, it might find the keyword "currency_menu" and return "Gold".

    To me this should work pretty well if I choose to ever localize in the future, theoretically I can just load a new language into the array, and switch the spritefonts for ones with the languages alphabet.

    Does this make sense? Is this a bad idea? I've never considered building for future localization until now.

  • As a quick update, oosyrag's suggestion worked pretty well, though I didn't use the container idea. Mainly because this only needs to be checked during lane changes, so I create a "LaneChecker" object in the function that checks to see if the lane the player is trying to move into is obstruction free. This object is created, positioned, and sized based on the players position and VectorX values, and then I just check to see if it is overlapping anything in the new lane.

    Regardless of if it is or isn't, the object is destroyed immediately at the end of the checker function.

    Thanks for the suggestion oosyrag! It's much more consistent than the old patch-job I had, and it was easy to test by simply not destroying the lanechecker object at the end of the function and changing its sprite based on whether it would allow a lane change or not.

  • That makes sense, its not quite as self contained as I'd hoped but it does seem straighforward, I'll try it out and see how it goes!
