`Jammer`

Systems: C64, MEGA65, PLUS4, C128
Parameters: n,n

Jammer([number], [number]);

[number 1] - raster line number
[number 2] - color number

Description

Jammer is a debug function that will jam the computer if the current raster line is larger than the value provided in parameter 1. If the system is jammed, the background color is set to parameter 2.

Useful for debugging raster effects that are too slow.

Example


@define DEBUG_MODE 1

interrupt MyRaster();
begin
        StartIRQ(@useKernal);

        PerFormSomeTediousTask();

        // if debug mode flag is set
@ifdef DEBUG_MODE
        // if current raster line hits 200, jam the computer with a blue background
        Jammer(200,BLUE);
@endif
        closeIRQ();
end;
