hello

The command CURVEVALUE() is a very handy and easy shortcut for decelleration but is there an equally easy shortcut for accelleration?

I'm not sure what the problem is.

speed# = curvevalue(speed#, maxspeed#, 20.0) `-- accelerate
speed# = curvevalue(speed#, 0.0, 20.0) `-- decelerate

I could be wrong on the syntax for curvevalue ...

Can I ask you a Question?
What is it?
It's an interrogative form of sentence, used to test knowledge. But that's not important right now.

The problem is:

To go from say 100 - 0 or 0 - 100 CURVEVALUE() will start off with a large step and slowly reduce the step until the goal is reached.

What I want is the step to start off slowly and steadliy increase until the goal is reached.

My latest project has no name - feel free to suggest one. Think 'Lunar Lander' with multiplayer, guns and bombs!

On a similar subject:

Does CURVEANGLE() perform the same function as combining CURVEVALUE() with WRAPVALUE() or does it perform something completely different?

2nd question :
You should check if curveangle will go the long way alround if prompted for "curving" 359 to 1 deg...(I'm away from my dbp )

Currently coding: 3d-2d latitude/longitude
Recent coding: elliptical orbits
