It’s still not 100% clear but I’ll give it a shot.
So I’m guessing you have an object moving along the top line left to right, and you want a second object to be on the line below, so that both objects will hit the right yellow line at the same time while moving in parallel?
If that’s the case set the second object’s speed and angle of motion to be the same as the first. Then you can either do
Object2: set position to object1
Object2: move 32 pixels at angle self.bullet.angleOfMotion+90
Or you can do:
Object2: set position to (object1.x+cos(self.bullet.angleOfMotion+90)*32, object1.y+sin(self.bullet.angleOfMotion+90)*32)
Where the 32 is the pixel offset.
