Viewport

• Viewport space represents a normalized position relative to the camera.
• ViewportToWorldPoint() converts a normalized position on the screen to a in 3D position in world space.

Parallax Scrolling

• Multiple image layers scrolling at different speeds.
• Gives an artificial sense of depth.
• More layers give more depth.

Audio in Three Parts

1. Audio Listener - to "hear" the audio.
2. Audio Source - to "play" the audio.
3. Audio File - the "sounds" that get played.

Mathf.Clamp(float value, float min, float max)

• Clamps the given value between the given minimum float and maximum float values.
• Returns the given value if it is within the minimum and maximum range.
  • Returns the minimum value if the given float value is less than the minimum.
  • Returns the maximum value if the given value is greater than the maximum value.
• Use Clamp to restrict a value to a range that is defined by the minimum and maximum values.
• NOTE: if the minimum value is is greater than the maximum value, the method returns the minimum value.
• Parameters:
  • value - the floating point value to restrict inside the range defined by the minimum and maximum values;
  • min - the minimum floating point value to compare against;
  • max - the maximum floating point value to compare against.
• Returns float (the float result between the minimum and maximum values).

Types of Loop

for loop

Runs a set number of times.

for(int i = 0; i < parent.childCount; i++)
{
    // do stuff
}

foreach loop

Works the same as a for loop but doesn't track the iterator.

foreach(type child in parent)
{
    // do stuff
}

while loop

Runs continuously while some condition is true.

while(condition == true)
{
    // do stuff
}

do-while loop

Runs once and then continuously repeats while some condition is true.

do
{
    // stuff
}
while(condition == true);
