2023-09-08: Prototype - Chick simulator

---

Game Design

Concept: Click on a “chick” to make it split into smaller chicks (in 3D space).

Control: Mouse clicks

Camera: Fixed 2D

Value: Visually satisfying

Budget: 24 Hours or by Sept 10th whichever comes first.

The Game

You can try out the game on Unity (WebGL for PC)

• Main UI to configure your simulation:
  • Spawn Rate: determines how many chicks are spawned
  • Explosiveness: determine the blast force being applied
  • Chick type: determines the spawn pattern

• Game Play
  • Click on Chicken/Chick to make it explode
  • “Chick Please” to spawn more chicks
  • “Reset” to change your chick
• Euphemism
  • None

Chick type showcase for nerds

• Standard Chick:

double radianTick = (360/ numChicksToSpawn) * (Math.PI/180);
double radius = 10;

for (int i=0; i <numChicksToSpawn; i++)
{
        double angle =  radianTick * i;
        float x = (float) (radius * Math.Cos(angle));
        float y = (float) (radius * Math.Sin(angle));

        Vector3 offset = new Vector3(x, y, 0);
        Vector3 pos = transform.position + offset;

        Instantiate(childChick, pos, transform.rotation);
}

• Cross Chick:

float spacing = 1f;
float distance = 0;
bool horizontalPlacement = true;
//Hmmm. I should rewrite this to use (radian=90 degree) + spacing ( 　゜，_ゝ゜)
//1st loop: Right, Left
//2nd loop: Up, Down
for (int i = 1; i <= numChicksToSpawn; i++)
{
    distance = i * spacing;

    if (horizontalPlacement)
    {
        Instantiate(childChick, pos + new Vector3(distance, 0), rotation);
        i++;
        if (i < numChicksToSpawn)
        {
            Instantiate(childChick, pos + new Vector3(-distance, 0), rotation);
        }
        horizontalPlacement = false;
    }
    else
    {
        Instantiate(childChick, pos + new Vector3(0, distance), rotation);
        i++;
        if (i < numChicksToSpawn)
        {
            Instantiate(childChick, pos + new Vector3(0, -distance), rotation);
        }
        horizontalPlacement = true;
    }
}

• Chaotic Chick:

public override void ClickAction()
{
    int numToSpawn = GameManager.Instance.spawnCount;
    float range = 25;
    float delayTime = (0.5f/numToSpawn) + 0.02f;
    StartCoroutine(SpawnChicks(numToSpawn, range, delayTime));
}

private IEnumerator SpawnChicks(int numToSpawn, float range, float delayTime)
{
    for (int i = 0; i < numToSpawn; i++)
    {
        SpawnChickAtRandomPos(range);
        yield return new WaitForSeconds(delayTime);
    }
    PushChicksAway(range*2);
    Destroy(gameObject);
}

private void SpawnChickAtRandomPos(float range)
{
   
    float posX = Random.Range(-range, range);
    float posY = Random.Range(-range, range);
    float posZ = transform.position.z + Random.Range(-range, range); 

    Instantiate(childChick, new Vector3(posX, posY, posZ), transform.rotation);
}

Nice to have features:

• Chicks to have trailing light to make it look like firework
• Chicks to spawn smaller versions of them-self
• Dynamically calculate the chicks spacing based on specified number to spawn and it’s size.
• Sound effects
