I have been thinking about a proper way to handle gravity in a 3d shooter.
Imagine your character is 16 units in height. The average human is say... 2 meters tall. This means that 1 meter is 8 units. the ratio is 1:8.
If gravity is expressed as 9.81 m/s^2 I believe then it would be equal to 78.48 units/s^2
However, this is only your acceleration per second...
If a game is running at 60 frames per second, this is where I become quite shaky, because you cannot just divide the gravity (78.48) by 60, and treat it as normal...
Assuming this conventional way of handling gravity is correct:
velocity.z += gravity;
z -= velocity.z;
How would you take into account there being 60 calculations per second? Yes, I have tried dividing the 78.48 by 60, but it does not feel correct...
