In my water script, space is to float up, and Q is the float down. I also limit movement speed so it portrays water conditions. The problem is when i float to the surface of the water, if i move a certain way, my characters swims out of the water into the air. So to fix this, i made a variable where if he is at the surface, it locks his y position so he stays on the surface until the player presses Q to go underwater. The problem is that when i press Q again. The y constraint on the rigid body goes haywire and launches me into the air. I dont know why this happens! Please help!
I have a underwater variable and and inwater variable, inWater means i am on the surface of the water.
Scroll down to where it says: if(inWater)
