Welcome all! Today I shall be presenting my TouchGrind park maker program!
Using information in this thread:
MacThemes Forum / [Tutorial] Touchgrind Park Editing || roobi
I have created a basic map editor, allowing users to create their own skate parks for touch grind.
This is the first release, I started work on this program about 7 hours ago, and now it is in a usable state. I give thanks to roobi, who wrote a thread on editing the xml of a map, which was the base for this project.

Please try to spread this to any Touch Grind Communities you know of
The reason I used gamemaker was because it had all the simple functions I needed already built in, and it helped avoid a complicated C program that would have had far more bugs. I may update the program to C or C++ eventually.

( The colours are different because I modified the base textures)
Please comment on what you think of the editor
Download:
Send big files the easy way. Files too large for email attachments? No problem!
To get the parks onto your iPod you need to SSH/USB into your iPod, navigate to:
private/var/mobile/applications
Then you need to find the folder containing TouchGrind, go into the touchgrind.app folder and then into 'parks'.
Backup the existing 'park-default.xml' and copy over your custom map created with the editor. Either reload touchgrind or just return to the touchgrind menu and reload the level.
I am currently working on making the editor 3d, where the objects added have 3d representations showing the relative heights and widths.
