Enforce max speed (new extension)

[tristanbob]

Limit the maximum speed an object will move from forces or from the physics behavior.

How to use:

• Add the behavior that matches the method you use to move the object (forces or physics)
• Set the maximum speed value in the behavior properties

Tips:

• This only affects movement from forces or physics
• This does not effect movement from other behaviors (platformer, top-down, draggable, etc)

I think I'm going to add a Minimum speed to this extension also. This way users can simply add acceleration and deceleration controls and let this extension handle the limits.

What should I call this extension, then? "SpeedRestrictions"

An object with a speed = 0 doesn't have any direction. It could make it difficult to do and I guess a minimum speed won't be very useful.

I would set up the minimum speed to only apply when the current speed is > 0 (it's the only way to know the direction).

I agree this is not going to be commonly used, but it could be useful in some cases. For instance, a weapon that pushes back enemies at different rates. The weapon could stop a small enemy, but the stronger ones would only be slowed (yes, this could be done in other ways).

It will only take me a minute to implement.

Oh, how silly I was. :)

I am not going to add MinimumSpeed to this PR, but perhaps I should change the name to SpeedRestrictions so that more restrictions could be added in the future?

[tristanbob]

I renamed this to "Speed Restrictions" and added "Max rotation speed".

I gave a quick look, it looks good. A max speed = 0 could be a valid use-case to stop the object.

I agree, I removed that condition.

I used it as an optimization for when the user didn't set the max speed, but I think it's more important to have the flexibility you described.
