Beginner question: formula to calculate velocity for a given direction. I'm writing my first very simple game and trying to determine the math required to calculate a X and Y velocity value if you're trying to send a particle in a certain direction (360 degrees).
30 lis 2012 · Velocity is simply put, something with speed and a direction. You can use velocity for hundreds of game related tasks, firing a bullet, flying a spaceship, etc. As part of the recipe, we will also look at normalizing update speed using elapsed time, so the code runs the same on various machines.
Velocity is the rate of motion in a specific direction. I'm going that-a-way at 30 kilometers per hour. My velocity is 30 kilometers per hour that-a-way. Average speed is described as a measure of distance divided by time. Velocity can be constant, or it can change (acceleration). Speed with a direction is velocity.
Speed and Velocity. Speed is how fast something moves. Velocity is speed with a direction. Saying Ariel the Dog runs at 9 km/h (kilometers per hour) is a speed. But saying he runs 9 km/h Westwards is a velocity.
