Square Root Thyme Function/Script

[BAZOOKA]

I would like to ask for the function of square rooting a number in thyme, as i am about to make a speed reader with the speed of the x-axis and the y-axis.
I would also like to ask if there is a thyme script called (readable(e.geom)).vel(0) and (readable(e.geom)).vel(1) like app.mousepos(0) and app.mousepos(1)

use x^0.5
or Math.sqrt(x)
where x is your variable

[BAZOOKA]

Thanks! I'll try it out.
How about the position thing?

[BAZOOKA]

Hey, this is weird.
I used both the functions:
onHitByLaser:

Code: Select all

{scene.my.a ^ 0.5}

and:

Code: Select all

{Math.sqrt(scene.my.a)

but neither worked! What is going on?!

[monstertje3]

When i put this in the console

Code: Select all

scene.my.var:=16

and put

Code: Select all

{[scene.my.var^0.5,2]}

in size, i get [4,2] (observed)

if i put

Code: Select all

scene.my.var=4

in the console i get a square. (geom resizes)
so it works with me (2.1.0 b12)

The function on 2.1.0 b12 does the job.

Code: Select all

math.vec.len(x)

[BAZOOKA]

hey people...i use v2.0.1...and i think the v2.0.2 b4 and v2.1.0 b12 are rather unreliable, so i still use v2.0.1. so what's the function for that?

[monstertje3]

The functions i said are in from the first algodoo versions (possibly even phun for Math.sqrt()), so you should have them, you probably typed incorectly or didn't declare the variable.
Upload the scene to algobox and show it here so we can see the problem and help you.

[BAZOOKA]

yeah sure...here it is.
oh damn. how to I put the scene up her?!!

[BAZOOKA]

wait. here it is

Math.sqrt Function

Code: Select all

(e)=>{
    Math.sqrt(scene.my.a)
}

I can make from this that you are trying to use the square root every collide, however your problem is that nothing actually saves. You have to say x=y, now you do y, where y just stays y and doesn't change. Try the next code:

Code: Select all

(e)=>{
    scene.my.a=Math.sqrt(scene.my.a)
}

Now every collision scene.my.a gets saved as Math.sqrt(scene.my.a) resulting in the root of scene.my.a (after some collisions it should come near to 0)

[BAZOOKA]

ahh...i've updated to version 2.1.0, so i'll check:

Code: Select all

math.vec.len(x)

if you have any alternatives, do say about them!
