I am trying to make a power up rarer and only appear after the power is enabled. Can someone give me an idea, if not , an example of how I could do this. I appreciate the help.

Make certain powerups rare and/or not appear until power is on. in Scripting

Ok something else it happening, it seems like having multiple while loops in get_next_powerup can only have one active at a time, causing the other powerup that isn't suppose to drop, drop.

I understand why it does this, as it doesnt continue a function unless a function is false.

What should I change to fix this? As in, how can I have multiple loops either "while" or something that works similar in one function, or if not possible, how would i run it in multiple threads?

here is part of the code

Code Snippet

Plaintext

while( powerup == "gtlad" && !flag("electricity_on") )
	{	
 
 
		if( level.zombie_powerup_index >= level.zombie_powerup_array.size )
		{
			level.zombie_powerup_index = 0;
			randomize_powerups();
		}
 
 
		powerup = level.zombie_powerup_array[level.zombie_powerup_index];
		level.zombie_powerup_index++;
 
		if( powerup != "gtlad" )
			return powerup;
 
 
		wait(0.05);
	}
	while( powerup == "fire_sale" && ( level.zombie_vars["zombie_powerup_fire_sale_on"] == true || level.chest_moved == false ) )
	{	
 
 
		if( level.zombie_powerup_index >= level.zombie_powerup_array.size )
		{
			level.zombie_powerup_index = 0;
			randomize_powerups();
		}
 
 
		powerup = level.zombie_powerup_array[level.zombie_powerup_index];
		level.zombie_powerup_index++;
 
		if( powerup != "fire_sale" )
			return powerup;
 
 
		wait(0.05);
	}

Edit: I changed the way this check works, based on how black ops handles it, and it works fine.

Yeah, that's probably a good idea. Would you maybe post your final working solution so this thread can be useful for others who want to do a similar thing?

Sure.

Make sure you backup _zombiemode_powerups.gsc before doing this.

1. There should be three instances of

Code Snippet

Plaintext

powerup = get_next_powerup()

one of which is in the function powerup_setup() and two in special_drop_setup()

replace

Code Snippet

Plaintext

powerup = get_next_powerup()

with

Code Snippet

Plaintext

powerup = get_valid_powerup()

2. Replace the entire get_next_powerup() function with

Code Snippet

Plaintext

get_next_powerup()
{
	powerup = level.zombie_powerup_array[ level.zombie_powerup_index ];

	level.zombie_powerup_index++;
	if( level.zombie_powerup_index >= level.zombie_powerup_array.size )
	{
		level.zombie_powerup_index = 0;
		randomize_powerups();
	}

	return powerup;
}

3. Below this function place

Code Snippet

Plaintext

get_valid_powerup()
{
	powerup = get_next_powerup();
	while( 1 )
	{
		// Carpenter needs 5 destroyed windows
		if( powerup == "carpenter" && get_num_window_destroyed() < 5 )
		{	
			powerup = get_next_powerup();
		}		
		else
		{
			return( powerup );
		}
	}
}

And if you are not adding any custom perks, you are done, otherwise continue below for an example on how to add custom perks to this function.

4. If you would like to add a custom powerup to this, lets say to add a random perk powerup with the name of "gtlad" to make it more rare and not drop until the power is on you would add

Code Snippet

Plaintext

		else if ( powerup == "gtlad" && ( randomint(100) > 25 || !flag("electricity_on") ) )
		{
			powerup = get_next_powerup();
		}

after

Code Snippet

Plaintext

		if( powerup == "carpenter" && get_num_window_destroyed() < 5 )
		{	
			powerup = get_next_powerup();
		}

so it looks like

Code Snippet

Plaintext

get_valid_powerup()
{
	powerup = get_next_powerup();
	while( 1 )
	{
		// Carpenter needs 5 destroyed windows
		if( powerup == "carpenter" && get_num_window_destroyed() < 5 )
		{	
			powerup = get_next_powerup();
		}
		else if ( powerup == "gtlad" && ( randomint(100) > 25 || !flag("electricity_on") ) )
		{
			powerup = get_next_powerup();
		}		
		else
		{
			return( powerup );
		}
	}
}

Where increasing the value 25 will make it less rare, and lowering it will make it more rare.

And you are done!
