simple 360 movement and trajectory

[anatol]

Help me please. I can`t understand why my trajectory is so bad

If you could give a test .mfa will be great.
For now I can say that to me it is strange how you put the parameters in the ATan2 function, you need a dY/dX, in the second parameter you inverted the order of the objects X coordinates.
You are doing something like...
(Y2-Y1)/(X1-X2)
but you need a
(Y2-Y1)/(X2-X1)
this i think is one point to check.

Ok , here is mfa file
BTW - I use this formula

Sorry I tried but cant find a solution.
If I understood the matter you are trying to make the "man2" active move toward the "point" active in a straight line.
I made a differend .mfa from the start to da the thing in may way and I have your same problem, a two line trajectory, now I think it is a problem on the precision of the calcolus made by Fusion or something like this.
I tried to force the calcolus using floating point number by using *1.0 and the like, the result is a little bit different but you can always see the two different lines trajectoryes.
I have no idea sorry.

Modified your expression a little. I can't exactly say why what you had done wasn't working. My math skills are a bit terrible and I always approach vector movement the same way.

I used a similar approach as you, the only difference is splitting the calculation and the position setting, probably this is the core of the problem.

Thanks for your help guys .
