SP3 Useful controller scripts

Wacov

I thought it'd be good to have a thread where people can post useful code to go in joint's controller boxes; for people (like me ) who have no experience with ruby script.

0.5-(input)
On a motor joint, this will allow reverse motion

Math.sin(frame/10.0)/3.0
Makes a servo oscillate

Time.now.sec*(1/60.0)
Similar to above, but moves every second

You can use multiple inputs as a single controller:
leftx+rightx

I tried to make an if function work, but it doesn't let you use spaces.

CPhillips

I fixed the spaces bug in the next version. Without spaces it looks like this:

if(frame<30);0.0;else;1.0;end

You can also combine sliders
((0.5-righty)*slider("MaxSpeed"))-slider("Trim")

Also sliders can take be configured:

slider("Zero",0) <--Slider has a default position of 0 instead of 0.5
slider("Ten",10,0,10) <--Slider goes from 0-10 and has a default position of 10

There is a bug and sliders don't initial show the correct position. Quickly click it to make it update.

wow thanks!

I need a script for a motor using the triggers (joyRY) and the a button. When the right trigger is pressed (<0.5 for me) the motor should spin, and if a is pressed with the right trigger, it should spin at twice the speed. At 0.5, the motor should be allowed to spin freely (if possible) and a should have no effect. Above 0.5 (left trigger) the motor should stop spinning completely for 2 seconds, then go into reverse at half the normal speed, again with a having no effect.

I hope this isn't too complicated

This is for a car with 'boost' that can brake and reverse using the same button.

How do I make the keyboard keys start at default position of Zero
or can't I?
like what I want is to not be able go backwards with a motor but start at zero

CPhillips

rightx-0.5

For keyboard right/left

Any chance a guide or tutorial will be made to explain how to use these codes? It doesn't seem like something you could just pick up and figure out in a few minutes. Oh, and what do you type in the box to duplicate the object connected to the joint, like in the preview video?

Oh, and to make thrusters/magnets controllable:

(0.5-righty)*100000

0.5-: not necessary, but allows reverse directions. 0.8- would make it go 80%forward, 0.5- makes it half and half, so neutral means no thrust, and 0.2- would make it go 20% forwards.

right: right or left, which joystick to use/ wasd or arrow keys.

y: x or y, left and right, or up and down.

*100000: a *, and the strength of the thruster/magnet.

Will the beta version have the copy function?

CPhillips

I just figured out how to make the copy function work. Its now called Emitters and it will be in next version.

do you know what controller scripts are used to make a keyboard key do an action
(like the spacebar, or letters other than WAS and D),
or for a slider to multiply an object like in the pre-release video?

Also, do you know why the script

(lefty-0.5)*300+slider('hover')*150

won't work in a thruster controller box? without the '-0.5', it seems to work, but I can't get it to do what I'm trying to.

that worked fine for me though the controls were switched so I did this

-(lefty-0.5)*300+slider('hover')*150

how do you make a motor controled by the arrow keys and have reverse?

BTM

righty-0.5

right: controlled by right joystick, or keyboard arrow keys. left would be left joystick, or WASD keys.

y: y= up and down. x=left and right.

-0.5: makes .5 of the speed going backwards, in other words, allows reverse. you could also put 0.5- before righty, if the motor is going in the wrong direction.

Oh, and Phy, thanks; but for me, only half the controls were reversed: I managed to fix it after though.

Thanks

Not yet. But I think I am going to add something like

key("space") or key("1")

Mulitply an object will be the new emitters.

Your script should work as far as I can tell.
