In other words, if it took 1/60s, then delta is 1.0, if it took 1/30s, then delta is 0.5. I want to find the acceleration a that will bring it to a speed of 0.2 pixels per timestep by the time it has traveled d.Īlso because this happens in a game loop, a variable delta is passed through to each action, which is the multiple of 1/60s that the last timestep took. It is driving at 2 pixels per timestep, where a timestep is 1/60 of a second. I have a car c that is 64 pixels from its destination, so d=64. Let me be more specific now that I've got some more ideas from you all: A lot of what I needed was just some help thinking about this. So essentially it will start stopping slowly then will eventually stop more abruptly, sort of like a car in real life.Īll right, thanks for the great responses.

So, V0 constantly is changed to be V0 from last timestep plus the a that was calculated last timestep.
The reason this becomes a programming-specific question is because a needs to be recalculated every single timestep as the car keeps stopping. T, or the amount of time I want to take to reach the end of my pathĭ, or the distance I want to go as I change from V0 to VfĪ, or the acceleration needed to go from V0 to Vf Vf, or the speed I want to reach (typically 0) Basically I have a car that can be going at a large range of speeds and needs to slow down and stop over a given distance and time as it reaches the end of its path. I've tried the typical physics equations for this but none of them really work because the equations deal with constant acceleration and mine will need to change to work correctly.
