How do I make balls to be "juggled" ?

it's an enemy juggling 4 balls at the same time. How to code the movement of the balls?

Note: there are supposed to be multiple instances of the juggler enemy.

Not sure if it would look good, but based on the picture shown, you could try making an orbital movement.

You will need:

-Ball

-Origin point //Image point on the enemy ( user for the ball to orbit around)

-variable Angle

-variable Speed

-variable Radius

On an every tick event position the ball using the following:

local variable "rad"(radians) = angle * (Math.PI / 180) // here we convert the angle to radians

ball> set X> origin.x + radius * Math.cos(rad)

ball> set Y> origin.y + radius * Math.sin(rad)

angle > add value > speed // the angle variable is what defines the position of the ball..if you don't increase it the ball won't move

..

Another try, sync 2 sines behaviours, one horizontal and one vertical, could also give you this effect.
