Sector_SetGravity
From ZDoom Wiki
216:Sector_SetGravity (tag, ipart, fpart)
tag: Tag of affected sector ipart: Integral part of the gravity multiplier fpart: Fractional part of the gravity multiplier
Sets the amount of gravity in a sector. The actual formula used is sv_gravity * (ipart + fracpart * 0.01). SV_Gravity is a cvar that defines "normal" gravity. So Sector_SetGravity (1, 0, 50) would set a sector to half normal gravity, Sector_SetGravity (1, 2, 0) would be double normal gravity, Sector_SetGravity (1, 1, 0) would be normal gravity, etc.
