How do I make multiple loops?

is the loop im working with. It freezes, so the loops arent closing.

just to summarize it. its going through each tile y1-x1-,,,,x30 finding a value thats 4.

then its checking each tile past that adding 1 to plusrightvalue to work out how many tiles are next to each other.

then, its adding 1 to axisY to check on the next Y layer the same origional loop at y2-x1,,,,,,,x30

honestly.. im winging this hard. im not competent in loops, hence my multiple poor descriptions.

ANY help on multiple loops is deeply appreciated.

im 4 days in on this. but when its done i can work on pathfinding. battles, and non imp digging jobs

If it freezes it’s a logic error somewhere in your loop events where they never end so it becomes an infinite loop.

To debug where the error is I usually write it a bit at a time and make sure it works for the simpler stuff before adding more to it. That way it’s easier to track when you introduce the error.

Another idea is to try to use the debugger to step through the events. Although I haven’t really used it and I’m not sure how detailed it’s able to step through your events.

You could also use “repeat” or “for” instead of “while” for your loops. With those a logic error would just not work instead of freezing. Also tweaking your logic to use those loop conditions instead may help fix the logic anyways.

Once you get it not to freeze you could log values to the console or editbox as your events run. And that could be a tool to see what is happening and maybe help you spot where to look for the error.

Just reading the events and running them in your mind sometimes works too. But breaking things down to simpler steps helps more.

Anyways, those are some strategies I use.

I used to be better at debugging others code but lack the time and patience lately.

What you’re running into with using all those while loops is there are many more places for the code to fail so it’s too tall an order to debug from a screenshot. A minimal example to download is better for other users to fiddle with if they get the urge to give debugging a go.

There could be some action or condition that’s not working as you expected. For that I often find it useful to do small tests with them to better understand what they are doing.

When using "While" loops I always add this condition to prevent infinite loops:

loopindex<100000

So even if you create an infinite loop by accident, at least it won't freeze.

i made it not transparent.. maybe that helps visualise it

ok. best way to describe it.

just check up

now with check right active also

both are enabled

but it will just do the first loop. it wont do multiple. THIS is what i mean by how do i do multiple loops,

i think ive got it.

its not logical to me. but, its ending after 1 loop. so, i just need the ending of spawning the sprite to calculate the total accumulated values for up down left right.

well... its a mess. but working ish

Loops are actually easy. Algorithms can be harder, especially when making them from scratch.

So what are you trying to do exactly? Do you want to know all the tiles connected to a certain tile? You can do that with a flood fill algorithm. That could help narrow your search for how people solved that kind of thing before.

I get lost though when you mention other things you’re trying to do and I’m not seeing a lot of connection. It probably is because I’ve never played the game you’re replicating.

if you think i can flood fill an overlapping tilemap: then create a room from it. i am 100% down to try!

i wanted to spawn a tilemap that had tiles set in the room. so i could pathfind to the room. and it would be eisier to choose a tile

its working... its placing things perfectly, and its a tile map. ill need to merge them, or set a variable to show what room it is

but its working!
