Is there a way to measure the instantaneous speed of an object?

What I'm doing is, I have two platforms. On the first one, I have some "rockets" from where they will be launched, and on the other platform, they must "land." However, I need to know the speed at which the rocket reaches the platform because if it's too fast, it should explode.

The larger platform is where it takes off, and the smaller platform is where it should land. I will implement a neural network to train and solve this; that's why I can't simply create an algorithm that starts a timer when the onKeyDown event is triggered and stops it when the onKeyRelease event is triggered. However, I need to know the speed.

If you're using body() component you can get rocket.vel which gives you a Vec2 of its current velocity. It's available since v3000.1.17.

Even without this, you can use onUpdate() and keep track of object's position each frame and calculate the difference to get the velocity last frame
