| | | | |
| − | Fades the screen to the colour specified, either as literal values or values from memory, using the type of fade specified by ''T''.
| + | See [[FADE]] for full details. |
| − | | |
| − | Fades are linear tweens that sit above the field. The from color and to color of the tweens are detailed below. After the tween has completed, the fades also set or do not set a holding color. For example, some fades go from the field colors to a light coloured overlay, but once finish, reset to back to field backgrounds.
| |
| − | | |
| − | The transition fades between fields and menus do not appear to affected by this op code.
| |
| − | | |
| − | The overlay sits infront of field models and background (apart from any special models with KAWAI or SHINE effects). It also sits behind any messages that appear on the screen.
| |
| − | | |
| − | If a FADE (or NFADE) is in progress but another FADE (or NFADE) is called, the current fade is stopped and the new one continues. Both op codes control, what essentially is, a single fade layer, I believe...
| |
| − | | |
| − | ''Note: Where colorBlack is mentioned, this essentially means 'transparent', eg you see the field without any overlay''
| |
| − | | |
| − | ==== Speed ====
| |
| − | | |
| − | The speed of the fade is specified by ''S'', and is base on:
| |
| − | | |
| − | 1 -> 240 frames -> 8 secs
| |
| − | 2 -> 120 frames -> 4 secs
| |
| − | 4 -> 60 frames -> 2 secs
| |
| − | 8 -> 30 frames -> 1 secs
| |
| − | 16 -> 15 frames -> 0.5 secs
| |
| − | 32 -> 7.5 frames -> 0.25 secs
| |
| − | | |
| − | In the table below, I refer to a calculation formula ''speedToSeconds'' for ''S'' to seconds is represented as:
| |
| − | | |
| − | const speedToSeconds = (speed) => {
| |
| − | return 8 / Math.pow(2, Math.log2(speed))
| |
| − | }
| |
| − | | |
| − | With 'NFADE', the speed calculation is not required, the fade speed ''S'' represents the frame count for the fade.
| |
| − | | |
| − | ==== Adjust ====
| |
| − | If the type id is odd, the adjust is 0xFF, if even, it is 0x00.
| |
| − | Whilst I haven't gone into depth with the adjust, it seemingly affects the wait for (FADEW). If set as per the table below, then the fade will take the time take as above and the FADEW will resolve once completed.
| |
| − | | |
| − | ==== Colours ====
| |
| − | Simple formulas based on the passed ''r'', ''g'', ''b'' values:
| |
| − | | |
| − | colorBlack -> rgb(0, 0, 0)
| |
| − | colorStandard -> rgb(r, g, b)
| |
| − | colorInverse1 -> rgb(0xFF - r, 0xFF - g, 0xFF - b)
| |
| − | colorInverse4 -> rgb(4 * (0xFF - r), 4 * (0xFF - g), 4 * (0xFF - b))
| |
| − | | |
| − | Frame by frame, the tweens will calculate the correct values between the '''from''' and '''to''' colours over the period of time of the fade.
| |
| − | Eg: FROM rgb(10,10,10) -> TO rgb(30,20,10) will increase like this:
| |
| − | | |
| − | rgb(10,10,10)
| |
| − | rgb(12,11,10)
| |
| − | rgb(14,12,10)
| |
| − | rgb(16,13,10)
| |
| − | rgb(18,14,10)
| |
| − | rgb(20,15,10)
| |
| − | rgb(22,16,10)
| |
| − | rgb(24,17,10)
| |
| − | rgb(26,18,10)
| |
| − | rgb(29,19,10)
| |
| − | rgb(30,20,10)
| |
| − | | |
| − | ==== Blending Modes ====
| |
| − | | |
| − | Whilst it seems as though a fade my be a gradual opacity, in FF7, it isn't. Instead it is a blending of colors ontop of each other.
| |
| − | Eg: We have a 2 pixel, a dark red one and a dark blue one and an orange overly, we apply it like this:
| |
| − | | |
| − | GREEN rgb( 40, 150, 70) -> BLEND DARK BLUE rgb( 50, 60, 130) ADDITIVE -> rgb( 90, 210, 200)
| |
| − | GREEN rgb( 40, 150, 70) -> BLEND DARK BLUE rgb( 50, 60, 130) SUBTRACTIVE -> rgb( 0, 90, 0)
| |
| − | ORANGE rgb(255, 130, 0) -> BLEND DARK BLUE rgb( 50, 60, 130) ADDITIVE -> rgb(255, 190, 130)
| |
| − | ORANGE rgb(255, 130, 0) -> BLEND DARK BLUE rgb( 50, 60, 130) SUBTRACTIVE -> rgb(205, 70, 0)
| |
| − | | |
| − | ''Note: Values are clamped below 0x00 and above 0xFF''
