How to make a sprite move in half circles?

• 7 posts
• The title explains it all.

• It actually doesn't..

What do you want to happen at the end of the half a circle?

Should the sprite slowdown and speed up or just change direction while keeping speed?

I guess a little fooling around with the sine behaviour could do the trick..

• You could ofcourse also just program it yourself by setting the sprite to the center of the circle and adding a certain number to the angle and moving the sprite the radius of the circle every tick..

I want the sprite to turn when it has moved a half circle and move a half circle to the other direction. If you don't know what i mean whit a half circle imagine a rainbows shape. I know that i am probably going to use the Sine behavior i just want to know which offsetts i should use. I know how to make sprite move in a full circle but not in a half circle. Again i want the sprite to move left and rigth in a half circle.

Doing it with sine behaviour you would need a horizontal and a vertical one

make the vertical one half the period of the horizontal and have it start at 1/4 of the period

make the horizontal a little more than twice the magnitude of the vertical and you're done..

You could have fiddled with the numbers yourself, offcourse..
