I need help trying to understand how to implement gravity in game.
I think i understand the concept of this derivatives
1. Position Vector. position of an object
2. Velocity Vector . change in position over time.
3. acceleration is change in velocity over time.
My problem is how do implement gravity and force into the game?
I know the position of the player.
I know the direction it is facing by using sin and cos thetha..
can i not use the the direction vector as my velocity? That is one place in which i am confused. How do i use the velocity vector to move in the direction in which i am facing?
How do i get the acceleration of the player:
force = mass * acceleration;
acceleration = force/mass;
do i just set mass and force to be a random value?
Can someone please clarify this in a simple manner.
And if velocity is the change in position over time? What is the use of speed?
Thanks in advance.
