For the first loop, you need to divide the TileMap.Width by Tile Size and the same for the Height

Example:

We have a Tilemap that has (Tile size =32)

> 
For "Y" From 0 To floor(Tilemap.Height/32) -1
------For "X" From 0 To floor(Tilemap.Width/32) -1

+ Tile.At(loopindex("X"), loopindex("Y")) # -1


-> System: [Create object coin on layer "Tile" at
> 
> Tilemap.TileToPositionX(Loopindex("X"))
> Tilemap.TileToPositionY(Loopindex("Y"))
> 
> 
> 

Thanks for helping me, I did what you suggested and it goes through the entire tilemap in the loopindex but it ends up creating several coins overlapping the other and sometimes some tile that I deleted is filled and others not

Two options:

1. Loop through all tiles and check if they are empty.

2. Get Tilemap.TilesJSON of an empty tilemap and save it to a variable. When you need to check if a tilemap is empty, compare its TilesJSON with that string saved in the variable.

For example, the JSON of an empty tilemap may look like this:

> {"c2tilemap":true,"width":53,"height":30,"data":"1590x-1"}

But in your case it may be different.

Thanks for the help, I'll stick with option 1, as my tilemap is custom-sized and modified in real-time

Hi, I would like to know the advantage and disadvantage of saving a level in array and saving on the computer, I see that saving by array is more laborious but more satisfying, but I would like to know the difference between the two, whether in a matter of time or other things.

Hi, I would like to know how do I detect when a tilemap is empty without even a block, I need to do this to then delete the empty tilemap

Store the uid of any object created as your first x value.

You can then use indexof(uid) to get and delete the line of any specific object in the array.

yes I already do that, but I use a Global variable to memorize the last object created, so I need that when an object is deleted from the level the global variable needs to locate the object that was deleted and resume in the last state without having to leave empty lines backwards

Try to delete the event, save the project, close it. Then re-open the project and create the correct event.

If it still gives you the error, you need to post a bug report here:

https://github.com/Scirra/Construct-3-bugs

I told you not to approve the post that would be just for you admins to see and be aware, I don't know how to work on that Gifhud site I have difficulties in understanding the requirements when posting the bug so I posted it here, the error report is mentioned above , thanks.

Hi admin, I will share with you a bug, I will try to explain what happened I created an event to delete a tile from the Tilemap object and then I just tried to change the code in the tile delete event to delete tile with brush and it gave this fatal error , I know this is not the place to post bugs but I tried to post it on GiHUB and I don't know how to work on that site so I post it here so you don't have to approve this post just see the error and then you can reject the post, Thank you.

Hi guys, I have a doubt about my game that I'm creating "Level Editor" I created a method to save each new object that is created in the array, I created a variable to memorize the last saved object so whenever a new one is created it will never replace one object already saved in the array, but I'm having trouble with how to do it in case the player deletes an object, instead of leaving several lines of the array empty, simply deleting them and the variable of the last object saved without affecting the variable of the last object created.

As Ashley likes to say, Answer your own performance questions with measurements :)

rsrsrs

How much data are you talking about? If it's less than 1MB I wouldn't worry about it at all.

the array will be 2000 wide and 2 high

hi- guys, my question is the following, in my level editor game, i save the information of the positions of each object in array i use for each tile a tilemap that in my opinion got better when resizing the player in real time it will be easier for him and so I save the json of each tile in an array and I will do the same thing with enemy sprites and I would like to know which one takes more memory save the json of each sprites or save the position, X, Y , which is lighter and weighs less in the memory of the device to be rotated, because in each line of the array an object json is a large text and already the positions in my opinion less text in the lines of the lighter array is, please correct me if i'm wrong, thanks.
