__Sines & Cosines Can Do Magic__

If you haven't realized the capability of sines and cosines in making objects move in game then you are in for a treat.

In order to make the objects move you just have to set the x position & y position respectively.

In order to make the objects move you just have to set the x position & y position respectively.

Here are some of the things we will be making:

First we just make the ball travel in a circle.

The 'itrValue' is some value that keep changing every frame like Time.timeSinceLevelLoad

Position in x-axis : Sin(itrValue) * radius

Position in y-axis : Cos(itrValue) * radius

Now we will make it tilt towards a side:Position in y-axis : Cos(itrValue) * radius

Position in x-axis : Sin(itrValue) * radius

Position in y-axis : Cos(itrValue + offset) * radius

We will now make it move in a flower petal path:Position in y-axis : Cos(itrValue + offset) * radius

Position in x-axis : Sin(itrValue) * (radius + Cos(itrValue* frequency)

Position in y-axis : Cos(itrValue) * (radius + Cos(itrValue* frequency)

Position in y-axis : Cos(itrValue) * (radius + Cos(itrValue* frequency)

Now a random-esque path, useful when object need to move in a way that looks semi-random like the movement of a swarm of mosquitoes:

Position in x-axis : Sin(itrValue) * (radius + Cos(itrValue + Sin(itrValue * frequency))

Position in y-axis : Cos(itrValue) * (radius + Cos(itrValue+ Cos(itrValue* frequency))

Position in y-axis : Cos(itrValue) * (radius + Cos(itrValue+ Cos(itrValue* frequency))
