Cocos2d and Tiled

[Meredi86]

Hey guys, i have started having a look into cocos 2d this morning, my plan is to use it to create a game over the next year, so getting the basics laid out now.

I have been following a few of Ray Wenderlich's tutorials, and have come across this one:
How To Make a Tile Based Game with Cocos2D | Ray Wenderlich

Now i can get through the tutorial OK if i use the .tmx that he supplies with his code, but using my own code. However if i used Tiled to create my own "map" to use then i cant get past the launch image. The error i am getting is this:

cocos2d: CCTexture2D. Can't create Texture. UIImage is nil
2011-05-25 12:07:48.441 TileTestTwo[7513:207] cocos2d: Couldn't add image:../Work/Games tests/TileGame/TileGame/tmw_desert_spacing.png in CCTextureCache

The only thing i can think of being a problem is the space in the above url (Game tests) but i dont see why that should cause a problem. I have checked all file names, locations and they all check out to be correct. I have tried a clean and rebuild, i have created a new project, and a new map in Tiled and attempted that. still nothing. The only way that i can get it to work is by using the supplied .tmx "map" rather than my own.

I dont want to move ahead of this tutorial if i cant even get this working, but i cant see why it wouldnt be working.

I think (i can only tell by dates of posts) that there will be difference in the Xcode version i am using (i am on 4) i guess as it was june 2010 that tutorial was release that it was done in Xcode 3. Also there seems to have been an update to cocos, i am using 1.0.0, again i would assume by date that Ray was using ~0.9. And now Tiled doesnt offer a java version (not that i could see) i guess there have been a fair few updates to that since Ray made the tutorial.

Could anyone help out here? i would be happy to email my test project as a zip if anyone feels it could help clear this up - its only a project to display a background map.

Sorry if this is a bit noobish, but im back to the drawing-board with this now.
Thanks in advance Joe

the image in on .app generated? are you sure that the image is not corrupted? try another image...

[Meredi86]

1. if i right click, show package contents on the .app i can see the image there: TileMap.tmx, as is: tmw_desert_spacing.png. So that should be ok from that point of view.

2. I am certain that the image isnt corrupted. I can open: tmw_desert_spacing.png in preview and there is nothing out of place, and i have saved two different .tmx's and tried both of them - with the same results.

3. I have tried the images from the tutorials source folder, and they work fine. though i only have to change the .tmx to make it work, which is why i assume that that has the problem.

In case this makes any difference. This is the xml from the tutorials .tmx:

<?xml version="1.0" encoding="UTF-8"?>
<map version="1.0" orientation="orthogonal" width="50" height="50" tilewidth="32" tileheight="32">
 <tileset firstgid="1" name="tmw_desert_spacing" tilewidth="32" tileheight="32" spacing="1" margin="1">
  <image source="tmw_desert_spacing.png"/>
 </tileset>
 <layer name="Background" width="50" height="50">
  <data encoding="base64" compression="gzip">
   H4sIAAAAAAAAA+3YIQ6AMAwF0AEKEATwSO5/RCoRmGHY2BMvaVLzRb/pkVI6gOZ0oQ9DAVlynbd5DFOYH3Y1WcMW9gKytGbJ8HXWFtXaaQAAAAAA/s8Pm1xuBvLpDW9ciGmfRhAnAAA=
  </data>
 </layer>
 <objectgroup name="Objects" width="50" height="50">
  <object name="SpawnPoint" x="51" y="301"/>
 </objectgroup>
</map>

And this is the xml from MY .tmx:

<?xml version="1.0" encoding="UTF-8"?>
<map version="1.0" orientation="orthogonal" width="50" height="50" tilewidth="32" tileheight="32">
 <tileset firstgid="1" name="tmw_desert_spacing" tilewidth="32" tileheight="32" spacing="1" margin="1">
  <image source="../Work/Games tests/TileGame/TileGame/tmw_desert_spacing.png" width="265" height="199"/>
 </tileset>
 <layer name="Background" width="50" height="50">
  <data encoding="base64" compression="zlib">
   eJztz6ENACAMALAFHDjw/H8mJzA5kooe0BMRBwD4WiuuJx+juOlRSvaxitvJBwAAAAAAAPB2Acs9FQk=
  </data>
 </layer>
</map>

as you can see there are one or two differences here, such as the compression. I dont know if that could change anything though, and if it does i am unaware as to how to solve such a problem. there seems to be no other save or compression options i can see in tiles.

Edit
Scratch that last sentence - i just found in preferences how to change the compression to the one the tutorial uses - off to test with fingers crossed!!

Edit two Nope with that changed and this as the new xml:

<?xml version="1.0" encoding="UTF-8"?>
<map version="1.0" orientation="orthogonal" width="50" height="50" tilewidth="32" tileheight="32">
 <tileset firstgid="1" name="tmw_desert_spacing" tilewidth="32" tileheight="32" spacing="1" margin="1">
  <image source="../Work/Games tests/TileGame/TileGame/tmw_desert_spacing.png" width="265" height="199"/>
 </tileset>
 <layer name="Background" width="50" height="50">
  <data encoding="base64" compression="gzip">
   H4sIAAAAAAAAA+3PoQ0AIAwAsAUcOPD8fyYnMDmSih7QExEHAPhaK64nH6O46VFK9rGK28kHAAAAAAAA8HYB8xytphAnAAA=
  </data>
 </layer>
</map>

I still get the same error.

[Meredi86]

got it. If you look at my xml there is a huge file path:

../Work/Games tests/TileGame/TileGame/tmw_desert_spacing.png

What i did was turn that into this:

tmw_desert_spacing.png

And hey presto it worked. I love figuring these things out

Next though is why did it save it with that url? and is there a way i can prevent it in the future?

[dany_dev]

because the editor generated it assuming a relative path....probably if you create it selecting the image that are already on the same directory of the tmx, will not add anyother that file name.....

[Meredi86]

ok so it was just the brows location that was messing me around. Cool that i believe is in my ability to fix and prevent

Thanks dany, i can move on to bigger and better things now
