IrrTiled - Tile map loader for Irrlicht

Post by TheMrCerebro »

Hello everybody :D !

Now that I am out of work and have free time, I have dedicated it to programming and other things :wink:
I have created some functions that make it possible to load and view files created with the Tiled https://www.mapeditor.org/ in an easy way just by including the "irrTiled.h" file in any project and writing a few lines of code.
In addition to 2d maps you can also create 3d environments with the same editor, I advise looking at the examples for an easy understanding.

Image Image

This is an example of how to add the code in a project, to do complex things I advise to check the source code of IrrTiled.

Code: Select all

 
#include "irrTiled.h"
 
using namespace irr;
using namespace core;
using namespace video;
 
int main()
{
    IrrlichtDevice* device = createDevice(EDT_OPENGL);
    device->setWindowCaption(L"irrTiled v1.1 - by TheMrCerebro");
 
    IVideoDriver* driver = device->getVideoDriver();
 
    //==============================================
    irrTiled* tld = new irrTiled("media/2dbasic.tmx",device);
    //==============================================
 
    while(device->run())
    {
        driver->beginScene(true, true, SColor(0,200,200,200));
 
	// Extracts data from all tile sets.
	for (u32 i = 0; i < tld->Tileset.size(); ++i)
	{
		TILESET ts = tld->Tileset[i];

		// Extracts data from all layers.
		for (u32 j = 0; j < tld->Layer.size(); ++j)
		{
			LAYER lyr = tld->Layer[j];

			for (u32 d = 0; d < lyr.Data.size(); ++d)
			{
				s32 id = lyr.Data[d] - ts.FirstGID;
				if (id >= 0)
				{
					// Tile position.
					s32 x = (d % lyr.Size.Width) * tld->TileSize.Width;
					s32 y = (d / lyr.Size.Width) * tld->TileSize.Height;

					// Draw the tile.
					driver->draw2DImage(ts.Image.Texture, vector2di(x, y), ts.SubRects[id], 0, lyr.TintColor, true);
				}
			}
		}
	}

        driver->endScene();
    }
 
    free(tld);
    
    device->drop();
 
    return 0;
}
 

NEW Version 1.1

Wow, that looks nice. Have to check out in more detail after work :) (bit confused right now how you get the 3d lamps and plants from a 2d editor - all you seem to use in code are boxes, guess I have to see it in action).

Thanks!!! :D

It may seem a bit confusing at first but it is very easy, look at the code:

Code: Select all

 
for (u32 i = 0; i < tld->aObjectGroup.size(); ++i)
    {
        OBJECTGROUP og = tld->aObjectGroup[i];
 
        for (u32 j = 0; j<og.aObject.size(); ++j)
        {
            OBJECT obj = og.aObject[j];
 
            f32 x = obj.x;
            f32 z = obj.y;
 
            if (og.name == "player")
            {
                cam->setPosition(vector3df(-x, 0.0f, z));
            }
            else
            {
                IBillboardSceneNode* sprite = 0;
                sprite = smgr->addBillboardSceneNode(0, dimension2df(tld->tileWidth, tld->tileWidth), vector3df(-x, 0.0f, z));
                sprite->setMaterialType(EMT_TRANSPARENT_ALPHA_CHANNEL_REF);
                sprite->setMaterialFlag(EMF_BILINEAR_FILTER, false);
 
                if (og.name == "plant")
                    sprite->setMaterialTexture(0, driver->getTexture("plant.png"));
                if (og.name == "lamp")
                    sprite->setMaterialTexture(0, driver->getTexture("lamp.png"));
                if (og.name == "table")
                    sprite->setMaterialTexture(0, driver->getTexture("table.png"));
                if (og.name == "guardian")
                    sprite->setMaterialTexture(0, driver->getTexture("guardian.png"));
            }
        }
    }
 
Simply the trees and the lamps are Billboards/Sprites. I use the position and the name of the objects on the map to locate them and know what they are.

Aah, OK! I only skipped quickly over code earlier and totally missed that :-D

Got it all working.

Btw, addCameraSceneNodeFPS has a parameter to prevent vertical movement, then you don't need the workaround in the loop.

Also not sure if this are your original project files. There's some tricks in VS, for example you can set the working directory in properties debuggin to your output directory. And if the output directory then is set in a way that it finds data automatically you can directly debug inside VS.

As for the printf warnings in lines like printf("- source: %s\n", ts.source); you have to use ts.source.c_str() as the compiler can't figure out the automatic conversion in this case (printf parameters are a bit typeless).

Anyway - it's really cool. I didn't even know about this map-editor before.

I did the code very quickly, when I saw that everything worked well I published it.
There are many fixes to be made, including the ones you say, irrTiled was just born a few days ago :lol:
About the VC I have started to use it recently, mine was the Code::Block and Mingw but I had to reject it because for other applications it was very basic.

This editor (Tiled) is perfect for making 2D games, whether RPG or action, many engines use it because it is free and quite complete. In my case I would like to add more functions to use it as a level editor in 3D environments, I know it seems crazy but to make games like Wolfenstein, Doom or Duke Nukem 3D it could work.

Thank you, TheMrCerebro.
Can't say I have a need for it just yet, but it's nice to have around.

please compile it with gcc, makes it more portable. there are about 5 or 6 errors compiling on linux, once its ready I can add it to the Demo's repo.

HI! I have released a new version :wink:
Version 1.1
- Source code cleanup.
- It is possible to load external tilesets in ".tsx" format.
- Improvement in the examples, easier to understand.
- More structures have been added (Group, ImageLayer, Tile, Animation, Frame)
- Images/Sprites corresponding to the game "Wolfenstein 3D" have been removed
to avoid Copyright problems.
See the first post to go to the download link.

...

Hi netpipe, I know it's easy but I don't have that much time to dedicate to this right now, i'm sorry :(

awesome it compiled and ran this time with minimal porting. I shall make some CBP files and upload it to the demos repository soon.

Hello! :wink:
I have updated the first post. I just configured irrTiled for use with Code::Blocks and simplified all the examples to be used in an easier way, I have uploaded everything to my github account (I registered a few days ago).
Possibly, soon, upload more examples of its use.

https://github.com/netpipe/Luna I have also implemented it here inside my game engine.
