Create a circle using cubes?
Ok, using two for loops one can create a a grid of cubes, just instantiate a cube increasingly on the x and y axis. How would one do this to create a circle or a ring?
Thanks guys in advanced!
The formula for a circle is x^2 + y^2 = radius^2. That isn't to hard to rearrange into code. I might come back and write it for you if I get the time.
I don't think this is correct. I just rearranged the equation so the x value would equal x and y would equal y. This should have printed a quarter of a circle but it just made a square.
for(int x = 0; x < 10; x++)
{
for (int y = 0; y < 10; y++)
{
Instantiate(cube, new Vector3(($$anonymous$$athf.Sqrt($$anonymous$$athf.Pow(y,2)+100)),$$anonymous$$athf.Sqrt($$anonymous$$athf.Pow(x,2)+100),0),Quaternion.identity);
}
}
Well, I'm still looking for a solution, but I see the error in the script above. The square root of anything to the second power (squared) is itself, so the script is just spawning a cube at x, y, 0. If I find a solution, I will let you know.
Thanks guys, found the answer though. I just derived the x and y values from cosine and sin.
public GameObject cube;
void Start()
{
int x, y;
int length = 50;
float angle = 0.0f;
float interval = 0.1f;
while (angle < 2 * Mathf.PI)
{
x = (int)(length * Mathf.Cos (angle));
y = (int)(length * Mathf.Sin (angle));
Instantiate(cube,new Vector3(x,y,0),Quaternion.identity);
angle += interval;
}
}
That's what I said!
You'll get a nicer looking circle if you make your interval some defined fraction of pi.
what if i want it to be spawned internally rather than just creating a border? @SnotE101
Then just Random.Range(0, length) the length in order to have it spawned randomly anywhere from the center up to the border.
For people who are trying to do this in 3D space , you just have to do is to change y to z so code will be something like this
public GameObject cube;
void Start()
{
int x, z;
int length = 50;
float angle = 0.0f;
float interval = 0.1f;
while (angle < 2 * Mathf.PI)
{
x = (int)(length * Mathf.Cos (angle));
z = (int)(length * Mathf.Sin (angle));
Instantiate(cube,new Vector3(x,0,z),Quaternion.identity);
angle += interval;
}
