  I also recommend checking out EasyStarJS, we are using it in our game for spirits pathfinding on large tilemaps with lots of obstacles.

  Here is an example with lots of instances moving without overlapping:

  I don't know JS that well.

  Google how to build a JSON string in Javascript. Then use setJsonString(str) to set it to JSON object.

  When LS works on one device/browser and doesn't work on another - this is a clear indication that it's not used correctly.

  Also, saving each element of the array in a separate key is woefully inefficient. You can save or load the entire array as JSON with a single action.

  On every tick add the distance between previous and current location of the sprite. Then save the current location in a pair of variables.

  On path found
  .. Sprite set prevX to self.x
  .. Sprite set prevY to self.y
  
  
  Sprite is moving along path
  .. Add distance(sprite.x, Sprite.y, Sprite.prevX, Sprite.prevY) to distTotal
  .. Sprite set prevX to self.x
  .. Sprite set prevY to self.y

  There may be a million different reasons.

  Run your project in Debug Mode (Shift+F4) and investigate yourself. Check the number of collision checks, number of objects, CPU and GPU profiler tabs.

  You can use tokenat and tokencount expressions to parse a list of values in a string:

  construct.net/en/make-games/manuals/construct-3/system-reference/system-expressions

  For "n" from 0 to (tokencount(s, ",")-1)
  .. Text append "Item #" & loopindex & "=" & tokenat(s, loopindex ",")
  

  Where s variable contains a string from the dictionary.

  But replacing values in the list will be tricky.

  I suggest you replace your dictionary with JSON object. JSON will be much easier to work with in this particular task.

  {
   "list1": [2,4], 
   "list2": [1,5], 
  .....
  }

  Add a black sprite on top with two effects - Screen and Bulge. (in that order)

  The bulge effect will only be in the area covered by that sprite.

  I often use this trick:

  Object on screen : // nothing in this event
  
  Else : // your actions here

  I tried to use your code but it gives me an error on key<> and I don't understand why.

  Sorry, I don't use JS often, it should be != instead of <>

  I assumed you know Javascript since you asked for a script solution?

  Here is a demo.

  I didn't understand how to use the first one.

  It's easy. Save Sprite.AsJSON to a text variable. Later, when you need to restore, create a new Sprite instance and use "Sprite Set From JSON" action - it will restore its position, instance variables and all other properties from the saved JSON.

  I would like the console.log to also write the object variables not related to the family.

  You know which variables are related to the family - simply exclude/ignore them when running the "for (var key in o.instVars)" loop.

  for (var key in o.instVars) {
  
   if (key!="FamVar1" && key!="FamVar2") {
   console.log(key + ": " + o.instVars[key]);
   }
  }

  It's probably only in preview. You will not see it when you export the game.

  I would probably use a timeline for this. When the character collides with the vine, disable Platform behavior, start the timeline. You will need to move the character above/below the vine on z-axis during the playback.
