Angle Reader For Phun Beta 5

[niffirg1]

Is there an accurate angle reader that is for Phun. I tried to make my own but it was a complete fail. Or just what is the code for this. I tried using math.acos But i did not work due to the lack of knowledge on Math. Coding

Code: Select all

    Scene.my.atan2=(P1, P2)=>{2 * math.atan((P2(1)-P1(1)) / (((((P2(0)-P1(0))^2) + (P2(1)-P1(1))^2) ^ 0.5) + (P2(0)-P1(0))))}

How's that? Give it two points and it will tell you the angle in radians.

atan2 tells angles in one direction to 180° and in the other direction to -180° but between 180° and -180° there's a gap in the definition and "NaN" will be displayed.

With the cosine you can display the absolute angle from 0° to 360°.

For the angle in radians:

Code: Select all

Scene.my.angle = (p1,p2) => { angle := math.acos((p2(0) - p1(0)) / ((p2(0) - p1(0))^2 + (p2(1) - p1(1))^2)^0.5); (p2(1) - p1(1)) < 0 ? {angle = 2*math.pi - angle} : {}; angle }


For the angle in degrees:

Code: Select all

Scene.my.angle = (p1,p2) => { angle := math.acos((p2(0) - p1(0)) / ((p2(0) - p1(0))^2 + (p2(1) - p1(1))^2)^0.5) * 180 / math.pi; (p2(1) - p1(1)) < 0 ? {angle = 360 - angle} : {}; angle }


If you want to display the angle of e.normal just type in this to OnCollide, OnLaserHit or OnHitByLaser:

Code: Select all

(e)=>{text = {"" + scene.my.angle([0, 0], e.normal)}}

The excellent K-Probe from Killinich:

Yes i have checked there but that is not really what i am looking for

Then what exactly are you looking for? You can use either ofthe scripts we posted and update them with beacons.

Just pick K-Probe and use scene.my.k1angle variable.
