public ArrayList walls=new ArrayList(); 

public void Start()
{
    walls[0         


        

Answer 1

Code should be like this :

//Adding List

paredes.Add(RetornaEmArrayList(279,275,0,0,90));
paredes.Add(RetornaEmArrayList(62,275,0,0,0));
paredes.Add(RetornaEmArrayList(62,275,62,0,90));
paredes.Add(RetornaEmArrayList(217,275,62,-62,0));
paredes.Add(RetornaEmArrayList(62,275,279,0,90));
paredes.Add(RetornaEmArrayList(41,275,279,0,0));
paredes.Add(RetornaEmArrayList(279,275,320,0,9));
paredes.Add(RetornaEmArrayList(320,275,0,-279,0));


//Traversing List

foreach(ArrayList item in paredes)
{
    float a=(float)item[0];
    float b=(float)item[1];
    float c=(float)item[2];
    float d=(float)item[3];
    float e=(float)item[4];
}
