@phbling01(View Post) The ctype doesn't effect anything in this case, only the tmp. Also, setting the tmp of graviton to 100000 for example will do the same thing as graviton with a tmp of 100 (max).
You can change how much gravity it produces by changing it's tmp (100 max, -100 min). If you set it to a positive value, it will produce positive gravity (same effect as PGRV) and if you set it to a negative value, it will produce negative gravity (same efect as NGRV).
