UNITMX, A Tiled Map editor TMX Importer for Unity [RELEASED]

Basically, i needed an open source way to do tiled maps with collisions in unity for my open game (more info about it here here and here), and since there were none i made one from scratch.

There are some things that could be improved (like removing doubles) but overall i feel like it's mostly ready for production.

Check Chaoseiro's repo for now too since it has more updates that i haven't merged yet: https://bitbucket.org/Chaoseiro/x-unitmx

You can download it (It's Free/libre) and check more details/guide/etc on the project repo

And since this post looks pretty empty with this, a lil image on how an imported mesh looks in the editor.



Update: fixed the repo link.

 

Im checking this out, thanks.

 

Just a quick comment after getting this set up. It would help to have the package as a unity package so all of the example assets don't lose their references to each other.

I'll have more feedback after I get a chance to try it out.

cheers

 

Great tool. I added square collision and I am using this in my project now. Thumbs up.

 

Thanks, i'll build a unity package once i fix a bug i found (last column items seem to have an incorrect index).

 

Hey guys!

I've forked this project and extended its features. You can grab it here! I'm also uploading it to the Asset Store, let's see if it gets approved

 

I'll take a look, do you want to merge it with the main branch? While i haven't commited much recently i'm pretty active.

 

Sorry didn't see your post :X

Of course you can merge it
I'll keep developing it, and, at least for now, new features will be added if I need them, as i'm actively using this code, but you are free to suggest or report any bug/error

 

I should be actively using it when i get some time since i have the project i created this for on pause due to lack of time. So you can expect some feedback from me

 

in Layer.cs
PosY should be changed as below...


public List<Vector2> renderUv ()
{

List<Vector2> uv = new List<Vector2> ();
int horizontalCellCount = _tileset.materialWidth / (_tileset.width + _tileset.tileBorder);
int verticalCellCount = _tileset.materialHeight / (_tileset.height + _tileset.tileBorder);
float cellWidth = ((float)_tileset.width / _tileset.materialWidth);
float cellHeight = ((float)_tileset.height / _tileset.materialHeight);
float borderWidth = ((float)_tileset.tileBorder / _tileset.materialWidth);
float borderHeight = ((float)_tileset.tileBorder / _tileset.materialHeight);
int totalCells = _width * _height;
int dataValue;
for (int i = 0; i < totalCells; i++) {
dataValue = int.Parse(_data .ToString ().Trim ());
if (dataValue != 0) {
dataValue = dataValue - _tileset.firstGID;
// int posY = dataValue / verticalCellCount;
int posY = dataValue / horizontalCellCount;
int posX = dataValue % horizontalCellCount;

float u = ((cellWidth + borderWidth) * posX) + borderWidth/2;
float v = 1.0f - ((cellHeight + borderHeight) * posY) - borderHeight/2;
uv.AddRange (new Vector2[] {
new Vector2 (u + cellWidth, v),
new Vector2 (u + cellWidth, v - cellHeight),
new Vector2 (u, v),
new Vector2 (u, v - cellHeight),
});
}
}
return uv;
}

 

On mine or Chaoseiro fork? I haven't merged the code yet (lack of time) so i'm not sure if he fixed whatever was broken in there.

 

on your "PolCPP-unitmx-2dfc2daa10bd.zip"
PoxY should be = dataValue / horizontalCellCount; (not = dataValue / verticalCellCount

in any way thanks for your open source code.

 

Thanks for the open source!

 

First of all this is absolutely awesome work.

I do however have a problem that I am hoping to solve. When the camera moves I am getting a lot of flickering between each tile.
Does anybody have an idea of what could be done to solve this?

 

I have one question to ask. I am a beginner to game programming. I wonder that if it is possible not to render whole map but only few tiles of map around player's current position. Because in my race game road is formed doughnut. there is no need to render some parts of map. Especially center of the map.

Thank you in advance

 

First of all thank you very much for making it open source. I believe this tool will help me.
