Dynamic trajectory line

Hi! I have some questions about trajectory line.

I have 2 sprites: A and B

I need the system to create a dynamic line from a to b, when I draw a finger from a to b

while the further apart a and b, the greater the arc of the line. But the arc should not be more than this

Something like this

Thank you

angry birds clone? LOL that's just a guess based on the pic. If you are making something like that or just looking to do the aim part of it... I seen videos on YouTube for this.

one possible solution is by using qarp() to do the curve.

Objects:

A, B, dot

Every tick

—- destroy dot

Repeat 10 times

—- create dot at lerp(A.x, B.x, (loopindex+1)/11), qarp(A.y, (A.y+B.y)/2-abs(A.x-B.x)/4, B.y, (loopindex+1)/11)

Dot.x > touch.x

—- destroy dot
