UpdateNPC_UpdateGravity()

void Terraria.NPC.UpdateNPC_UpdateGravity ( )

inlineprivate

Updates P:Terraria.NPC.maxFallSpeed and P:Terraria.NPC.gravity in line with vanilla behavior and resets F:Terraria.NPC.GravityMultiplier. Behavior can be modified with F:Terraria.NPC.GravityIgnoresType, F:Terraria.NPC.GravityIgnoresSpace, and F:Terraria.NPC.GravityIgnoresLiquid.
Certain NPC type ids may also cap velocity, see F:Terraria.NPC.GravityIgnoresType.
