Enemy IDs listed in the arguments have no hitbox. (Whether it's disabled or way off-screen)

I got one from Zoria a bit back:

ffc script IgnoreNPC{
    void run (int npc_id){
        Waitframes(5);
        while(true){
            for ( int q = Screen->NumNPCs(); q > 0; q-- ) {
                npc n = Screen->LoadNPC(q);
                if ( n->ID == npc_id ) {
                    n->CollDetection = false;
                    continue;
                }
            }
            Waitframe();
        }
    }
}

Don't know if it works for more than one enemy onscreen (haven't needed it for that :/).

I believe it works by moving the hitbox offscreen, meaning you can't affect the enemy either.

Wonderful! And it does work for multiple enemies of the same ID. Thank you!

For grins, this should allow up to eight npc IDs.
 
ffc script IgnoreNPCs
{
	void run()
	{
		Waitframes(5);
		while(true)
		{
			for ( int q = Screen->NumNPCs(); q > 0; --q ) 
			{
				npc n = Screen->LoadNPC(q);
				for ( int w = 0; w < 8; ++w )
				{
					if ( n->ID == this->InitD[w] )
					{
						n->CollDetection = false;
					}
				}
				
			}
			Waitframe();
		}
            
        }
}


P.S. The continue instruction in the prior script has no purpose, as the loop continues at where it was placed anyway.

It probably has no effect on the resulting ASM. I'm only mentioning it, as some might think it's mandatory for some reason. I don't know why I put it there, unless I had a condition that I inverted and forgot to remove it.
 
for ( int a = 0; a < 4; ++a )
{
    do_something();
//end of loop, so it continues back to its start}

for ( int b = 0; b < 4; ++b )
{
    do_something();
    continue; //superfluous
}


You want to use the continue instruction to prematurely return to the start of a loop.

 
for ( int a = 0; a < 4; ++a )
{
    if (!condition ) continue; // instructions after this will not 
                               // run if the condition evaluates true.
    do_something(); // Runs if the continue condition evaluates false.

}



My guess, is that I originally had:
 
ffc script IgnoreNPC
{
	void run(int npc_id)
	{
		Waitframes(5);
		while(true)
		{
			for ( int q = Screen->NumNPCs(); q > 0; --q ) 
			{
				npc n = Screen->LoadNPC(q);
				
				if ( n->ID != npc_id ) continue;
				n->CollDetection = false;

				
			}
			Waitframe();
		}
            
        }
}
(Note that this would have the same effect.)



If not that, then perhaps I had another condition in there (that I removed), or I was drunk when I wrote it. Any of these are plausible.

I know that it's mine, as it has a signature style element that no-one-else here uses. Can you spot it?

Further, I know approximately when I must've made that, due to two other choices: One logical that I've since refined, and the other a style choice that I've since changed.

Wait, so in the original script, how many enemies of the same Enemy ID does the script handle at once?

As many as exist on the screen.

The revision supports up to eight IDs: One for each D* arg.
