Allows us to set up multiple conditions for a chain together
if(/*condition*/)
{
//action 1
}
else if(/*condition 2*/)
{
//action 2
}
else if(/*condition 3*/)
{
//action 3
}
else //other conditions
//action 4, if no conditions are met
}Rule in nesting – if the first action happens, it will no longer check the succeeding conditions. If two conditions is mandatory, nest the second set of conditions separately.
|| and &&
Logical operation || (OR)
if(A || B) //A or B
}
//action
{
//example
if(gameState == 0)
{
gameState = 1;
countdown = 200;
}
else if(gameState == 1)
{
if(key == secretKey)
{
gameState = 3;
}
else if(key == hotKey || key == hotKey1 || key == hotKey2)
{
countdown += 15;
}
else if(random() > 0.5)
{
//
}
}
else if(gameState == 2)
{
gameState = 0;
}
else if(gameState == 3)
{
gameState = 0;
}When working on same conditions, full conditions must be written. role == A || role == B and not role == A || B
Logical Operator && (or)
if(role == A && role == B)
{
//action
}Variables normally cannot have two values at the same time.
