playing around with newton car example i removed some of the blocks they had used for the demo but after deleting them and compiling the level they are still there and can drive on them but you cant see them

Delete the "Levelname.cls" file.

Doesn't Newton.dll auto-create the class file?

i found out what was going on, i opened the level wmp or was it wmb (the main file you open to load wed) in wordpad and found that the $$w file had been renamed to VEHCL~1.$$w after renaming it to what it should be and reloading the .wmp it fixed its self but it still does it all the time by renaming it to VEHCL~1.$$w

its alot of hassle to having to keep closing the files renaming them and opening them again to check my level but it works.

Maybe to save the hassle...

is the "invisible" flag on the tires?

nope.

I recommend deleting all the "unneccessary files". Such as the $$w files, and such. And the newton class files as well. Also, if you need hep with Newton, check out the post linked at the bottom of my signature...
