TPTlover1012:

how about add my element then make HEAT a cooling thing

What? You don't make any sense at all.
I haven't done much work on my mod recently anyway because i've been playing minecraft, but eventually a new version will come out, with a few new elements.

Also, if anyone wants to try out powdertoy++, I compiled it myself. It has tons of features missing, but most of the main things work, except that opening a save won't do anything (possibly a problem caused by me, it used to work) and it crashes when you try to exit. You need the DLL's on the first page for this to work. If you have any other problems, I will probably not be able to fix it, because I am not working on this, I only compiled it. You'll just have to wait for the problems to be fixed eventually.

New Version Released

Version 11 - 2/21/12
Added PROP2 tool, you can draw properties on with the normal brush now. Improved decoration drawing speed and added a hex value display and floodfill to it. Changed menus of some elements. Added a new test icon for the favorites
menu. Added an update check, if there is a new version, you can use the link in the message of the day to download a zip file containing the next version of this mod. Added COND, only conducts to other COND with same tmp within a
tmp2 radius. Added PWHT, flood fill heats the element above it to it's temp. Use PROP on it to make it create other properties. Added rechargeable battery, set the tmp of battery to the maximum charge it can hold, METL to charge, PSCN/NSCN to turn on/off. Some other stuff not listed here.

The time between every version keeps getting farther apart, so I will try and make it smaller again with less new stuff in each version. This version adds 3 new elements: COND, PWHT, and rechargeable battery, and also adds PROP2 and changes the decoration editor/smudge tool a little. Edit: Actually the smudge tool is broken, I will fix it in the next version

Look in interface.h, I even have a comment on the line that does it. Also, you would have to edit drawtext in graphics.c a little because I added some more colors that the normal powder toy doesn't use when drawing text.

Version 12.1 Released (also made link direct)

Version 12 - 3/2/12
Added tabs. Hit the tab button in the quickoptions menu or press Ctrl to show a menu of all the tabs you have open. You can switch between them, or open a new one (what you are doing is copied over). Tabs are saved and not simulated
when you are not using them. Press shift to save pressure in stamps and saves, RCTRL to keep it when transforming stamps. Added fusion. see thread 12901 for more info. Added realistic mode, not by me and not too noticible. Autosave button, disabled by default. If Powder Toy unexpectidely closes, the next time you open it your work will appear. Fix decoration tools.

Version 12.1 - 3/3/12
bug fixes.

The main new features are tabs and fusion. Press t in the quickoptions menu to look at what tabs are open/switch between them. I was going to make a save to show off fusion, but it's late and BoredInSchool (the person who suggested it) is going to make some later. Version 12.1 will come secretly soon, because the intro still says it's version 10, although I did change it to 12 in some other text already. Also, the update check doesn't appear to work, I will just remove it.

Edit:
I made a quick example save for fusion, just open it in my mod:



It uses Newtonian gravity and way more hydrogen than needed, so it might be laggy on your computer.
