Simple RPM meter

[Kilinich]

Since Algodoo2 fire onCollide every step (not every frame), we can use simplified scripts for measuring:

Unsigned RPM from on collide (just make it collide for sure):

Code: Select all

scene.my.rpm = math.acos(e.normal(0) * e.this.normal(0) + e.normal(1) * e.this.normal(1)) * Sim.frequency * 9.5492966;
e.this.normal = e.normal;

neat! i never thought of it by using the scalar product.

btw do you know a way to control the frequency for lasers a bit better? because it seems that it not totally constant all the time. (or is it different in algodoo 2 now?)

[Kilinich]

In 2.0 onCollide fires every step and onLaserHit/onHitByLaser every frame (usually once per 1-2 or 3 steps).

Can't seem to get this to work on my scene's in algodoo - keeps jumping between figures that are less than 1 and then jumping up into the 1000's, only seems to show the right RPM once then jumps to a random figure :/

Foregt it - you have readable in Algodoo2
