Functional Sample: COLOR SPECIAL EFFECT

## Functional Samples: COLOR SPECIAL EFFECT

This is a sample of color special effects.

Source: `(AGBDIR)\src\samples\functional_sample\coleffsm\`

### Description

This is a sample of color special effects.
In this sample you can change the type of color special effects and turn OBJ semi-transparency ON/OFF.
BG0 is on the ground to the bottom-right, BG1 is in the air to the top-left, and the three Yoshis starting from the left are OBJ0 and OBJ1 and OBJ2.
The part falling off the lower-right side is a window, inside which the color special effects are OFF.
When OBJs are made semi-transparent and the color special effect is set to Luminosity UP or Luminosity DOWN, you will see no change in luminosity for parts of the OBJ that are semi-transparent. But you will notice a change in luminosity for those parts that are not semi-transparent (where the pixels directly underneath are not the second object).
Color special effects are OFF inside the Window, so they will have no effect.
However, a semi-transparent OBJ on top of the second object will be semi-transparent.
If there is no second object, semi-transparency will not arise.
Even if a moving OBJ overlaps a fellow OBJ, that fellow OBJ will not become semi-transparent.

### How to Operate

SELECT:
Return to Title Menu
START:
Change the special effect setting (Normal -> Alpha blend -> Luminosity UP -> Luminosity DOWN)
START button while pressing B Button:
Switch OBJ semi-transparency ON/OFF
Control Pad:
Move Yoshi 0
Control Pad while pressing B Button:
Move Yoshi 1
Control Pad while pressing A Button:
Move Yoshi 2
L Button:
Make EVA -1 and EVB +1
R Button:
Make EVA +1 and EVB -1
L Button while pressing B Button:
Make EVY -1
R Button while pressing B Button:
Make EVY +1
(EVA = coefficient for 1st (upper) object of alpha blend; EVB = coefficient for 2nd (lower) object of alpha blend; EVY = coefficient for change in luminosity.)
