Functions | |
| void | RunSceneTransitionEffect (s32 x, s32 y) |
| Starts the wave effect of caster sourceId on target targetId: fades the palettes toward a hue that shifts with the frame counter, and starts its per-frame update (FieldFx_UpdateMindReadWave) after 8 frames. | |
| void | BattleFx_FinishSceneAndReleaseHeapBlock (void) |
| Stops the wave effect: restores the caster's colours and the palettes and releases the effect's work. | |
| void | FieldFx_UpdateMindReadWave (void) |
| Scheduler callback of the wave effect: once its delay has run out, writes the next page of scanline offsets (a sine wave of 4 pixels either way), steps the colour fade and the hue, keeps the caster's colours lit, and every 60 frames sends three particles (object 281) from the target to the caster, with sound 130. | |
| void | BattleFx_ArmBg0HBlankDma (void) |
| Scheduler callback: restarts the HBlank DMA that writes BG0's horizontal scroll for each scanline from the wave's shown page. | |
| void | BattleFx_AdvanceHueCycle (void) |
| Moves the wave's hue on 4 degrees and works out its colour, each channel 4 to 11. | |
| void | FieldFx_ComputeHueChannels (s32 hue, s32 *r, s32 *g, s32 *b) |
| Works out red, green and blue (0 to 31 each, 16.16) for a hue in degrees (16.16). | |
| s32 | BattleFx_HueChannelRamp (s32 angle, s32 low, s32 high) |
| One colour channel's strength at a hue angle: rising from 0 to 60 degrees, high from 60 to 180, falling from 180 to 240, low elsewhere. | |
| s32 | Fixed_Remainder (s32 value, s32 divisor) |
| The 16.16 remainder of value divided by divisor (0 for a zero divisor). | |
| void | BattleFx_SetCallbackWhenTargetUnset (union FieldObject *fieldObject) |
| Per-frame update: once the object has arrived (no destination left), runs the script for untargeted objects. | |
| void | Ui_FillBank15PaletteGrey (void) |
| Turns colours 1 and 3 to 12 of BG palette 15 grey and starts the BG0 scanline scroll (BattleFx_ArmBg0HBlankDma). | |
| void | Ui_SetBank15PaletteAndClearRenderMode (void) |
| Stops the BG0 scanline scroll and restores BG palette 15. | |
