A simple script that simulates a lightning effect with an SFX. Useful so you don't have to calculate the frames until the SFX and flash sync together manually By this I mean it's mostly just plug and play. There are two versions of my script:

The first version (Lightning Effect A) needs to be set only once, and after that, you just attach it to an FFC and etc. Useful for putting this effect on various areas.

The second version (Lightning Effect B), has to be set each time you use it. Useful for making different screens than the rest, or something like that

VERSION A:

const int LIGHTNING_DELAY = 0; //Delay in frames until the effect repeats itself.
const int LIGHTNING_SFX = 0; //SFX to use. Self explanatory.
const int LIGHTNING_LAYER = 0; //Layer to draw the rectangle to. (Needs to be used by the screen).
const int LIGHTNING_COLOR = 0; //The rectangle is drawn using the specified index into the entire 256-element palette: for instance, passing in a color of 17 would use color 1 of cset 1.

VERSION B

The version that's not plug and play.
Arguments are as follows:
D0 is the delay in frames until the effect repeats itself.
D1 is the SFX to use. Self explanatory.
D2 is the Layer to draw the rectangle to. (Needs to be used by the screen).
D3 is the color of the rectangle using the specified index into the entire 256-element palette: for instance, passing in a color of 17 would use color 1 of cset 1.
