How to Cap Variables?

Hi, I guess this isn't a 2d question, but I would mainly use this for 2D, so why not! My question is how to cap a variable like, your character speeds up the more he runs, but it stops at a certain speed, or the the more you push the space button, the character jumps higher, but stops after the a certain height for example. Thanks for the answers in advance!

 

Mathf.Clamp() and related methods might be what you want in some cases. Give it a variable input, the minimum and the maximum. If you're adding force via physics it's probably better to keep a running total and stop adding when at maximum. Clamping values is neat and tidy when not using physics though.

 

So if I was usin Physics then how would I stop at the max value?
Ps. Thanks for the first answer, i would just like the know the answer for physics too.

 

There's another similar thread about jumping: http://forum.unity3d.com/threads/jumping-in-platform-2d.353610/#post-2286776

You should be able to check the current force on the rigidbody, or at least track how much you've added and stop when near/at maximum. Note that floats tend to be approximations, so methods like Mathf.Approximately() exist
