Modern mouse follow

[Kilinich]

Ok, next evolution of mouse follow script - no lasers, no scene.my variables.

Script for hinge bendTarget:

Code: Select all

{
    v := app.mousepos - (readable((Scene.entityByGeomID((readable(owner)).geom1)))).pos;
    (v(0) < 0 ? math.pi : 0) - math.atan(v(1) / v(0))
}

It's phunlet-safe but script killed (need to be re-entered) on clone/copy-paste.

Simplest mouse follow

I'm using Algodoo beta for Education v2.0.1. Script for hinge bendTarget shows up as NaN. Pasted script in bendTarget, but it turns red and does not stay on closing script window.

Downloaded again and retried. Now works OK for left car. Does not work every time scene is loaded.

It's for beta9+

Thanks. Downloaded b10 and now everything works.

the code seems to fail in b12,

if you change the - into a + before math.atan, it correctly follows the mouse, but after undo the script needs to be re-entered.

Code: Select all

{
    v := app.mousepos - (readable((Scene.entityByGeomID((readable(owner)).geom1)))).pos;
    (v(0) < 0 ? math.pi : 0) + math.atan(v(1) / v(0))
}

in your scene, the undo also erases the script, but the +/- error is different there

[Kilinich]

No +/- error for me.

probably the attaching of the two geoms (wich one on top)
