CSV map error.

[erikhman]

I recently started programming in haxeflixel, and, like most of those who started doing this recently, the reason was FNF modding. But the knowledge that can be found in groups dedicated to it, are limited to problems typical for FNF. Therefore, it is difficult to find solutions there for the problems that arise when implementing original ideas. And that's exactly what I'm facing. I want to add a simple platformerState into the game to diversify the gameplay. But I'm having problems with the map. When I try to load a CSV file with a map, the game, for some reason, cannot find it.
Here i am trying to load the map in.

class WalkingState extends FlxState
{  
    var levelBounds:FlxGroup;
    var player:Player;
    var map:FlxTilemapExt;

    public function new(levelName:String)
    {
        super();
        switch (levelName)
        {
            case 'test':
            { 
                bgColor = 0xffcccccc;
                player = new Player(200, 200);
                map = new FlxTilemapExt();
                add(player);
                add(map.loadMapFromCSV("shared/images/map.csv", "shared/images/1.png", 16, 16));
                trace("Loaded succsesfully");
            }
            default:
            {
               bgColor = 0xffcccccc;
                player = new Player(200, 200);
                map = new FlxTilemapExt();
                add(player);
                add(map.loadMapFromCSV("shared/images/map.csv", "shared/images/1.png", 16, 16));
                trace("Loaded succsesfully");
            }
        }
    }
.
.
.
}

And here is the part of the code, where the error occurs.

public function loadMapFromCSV(MapData:String, TileGraphic:FlxTilemapGraphicAsset, TileWidth:Int = 0, TileHeight:Int = 0, ?AutoTile:FlxTilemapAutoTiling,
			StartingIndex:Int = 0, DrawIndex:Int = 1, CollideIndex:Int = 1)
	{
		// path to map data file?
		
		if (Assets.exists(MapData))    //<----For some reason it returns false
		{
			MapData = Assets.getText(MapData);
		}
.
.
.
	}

Moreover, everything works in this HaxeFlixel Demo (https://haxeflixel.com/demos/FlxTilemapExt/). As far as I understand, the problem should be in the project file, but I do not know what exactly i need to change in there. Here is a link to the vanilla version of the game I am modifying https://github.com/KadeDev/Kade-Engine/releases/tag/1.7. And, in case my theory with project file is correct, here is project file(as a txt, because i cant attach xml).
project.txt

I haven't created a level from csv before but looking at this codebase
https://github.com/HaxeFlixel/flixel-demos/blob/master/Platformers/FlxTilemapExt/source/PlayState.hx#L47

It looks like the file has been changed from .csv to .txt. Is this something you have tried?

[RichardBray]

Also, it would be good to check if you're asset path is correct. The reason the link I shared in the answer works is because the asset path has been specified in the Project.xml file
https://github.com/HaxeFlixel/flixel-demos/blob/master/Platformers/FlxTilemapExt/Project.xml#L34

I don't know if your shared path has been added there as well.

[erikhman]

I already tried changing it to .txt and it didnt work.
About asset path. I attached the Project.xml file as a txt one to the message above. I'm almost 100% sure, that the error is somehow related to the file. But you could see that the shared path is specified in there, so, i guess, there is something else that i'm missing.

[erikhman]

Also, in the HaxeFlixel demo you mentioned, I noticed some .hxproj file.
https://github.com/HaxeFlixel/flixel-demos/blob/master/Platformers/FlxTilemapExt/FlxTilemapExt.hxproj
Maybe that's the problem? I mean, I don't have one in my build.

[RichardBray]

Interesting spot. I'm not sure the .hxproj file has anything to do with it but it's worth asking @Gama11 who maintains the demos.

[Gama11]

.hxproj is not relevant, it's a FlashDevelop / HaxeDevelop project file (and has no impact on compilation).

[Geokureli]

can you tell us more about your assets folder structure? I noticed shared/images/ which is similar to the FNF assets layout, which is a very non-standard way of doing it. also what does your project.xml assets path look like?

If you're on VSCode you can right click any file in the left side file tree and get the relative path. I use this a lot because it's easy to misspell a file or type in the wrong path. if that doesn't work try taking a screenshot of the file in the file tree and posting that here

[erikhman]

May i ask you one final question? As you could see, i am using FlxTilemapExt, because of slopes collision support. Originally i was planning to implement curves into the game, like, make the ground a smooth sin(x)-like line. But i didnt find any examples of such idea in other games, so i moved on from curves to slopes. But i am not that experienced in Flixel, and in game developing in general. Is there some way to add curves into the game?

[Geokureli]

Ive never used tilemapExt, you might be better off asking in a new question

[RichardBray]

@erikhman For slopes, I wouldn't recommend using FlxTilemapExt since it's quite limited. I'd say use something like Echo which is an actual physics library.

[erikhman]

@RichardBray It actually looks much better than "flxtilemapext". I'll try to work with it, but just in case, I'd like to ask something.
Initially, I wanted to implement something like what is shown in the picture: the character should be able to move along a curved surface, while its sprite should rotate, depending on the derivative at current point of the curve. Do you happen to know how to implement it? Obviously, there is mathematics involved, so it seems to me that there must surely be an engine or library that solves this problem...

[RichardBray]

Ha, maybe this is a question for a new discussion thread but I think Echo can solve those problems. I haven't tried it with sprite rotation on slopes but I know that .

Even just following the instructions on this page https://gist.github.com/AustinEast/524db026a4fea298a0eebf19459131cc can produce some pretty decent slope physics.
