So this is just a simple little script I put together that allows players to buy an extra perk slot. This is very simple and easy to do, so nobody should have any problems with it

NOTE: Due to some issues people have been having, I highly reccomend installing Bam's perks the manual way (i.e. adding the scripts yourself and not using script placer z for them). Now, I only say this because I believe there may be a problem in the script if you do not install them the manual way or do not have them installed. I will re-write the script with the necessary changes and checks when I have the time and will update this topic. Thank you.

Step 1:
Open your map in radiant and place a script model of a perk bottle (or you can use a different model if you'd like), and give it this KVP:

Code Snippet

Plaintext

targetname : perk_bottle_model

Now place a trigger around the perk bottle (or whatever model you used), and give it the KVP:

Code Snippet

Plaintext

targetname : buy_slot_trigger

Save and close your map.

Step 2:
Go into WaWroot/mods/yourmapname/maps and open up YourMapName.gsc

Step 3:
Find this:

Code Snippet

Plaintext

maps\_zombiemode::main();

And directly under that line, paste this:

Code Snippet

Plaintext

thread buyable_perk_slot();

Now, paste this at the very bottom of the file:

Code Snippet

Plaintext

buyable_perk_slot()
	{
		level.perk_limit = 4; //Initial perk limit, feel free to change
		level.perk_limit_max = 8; //Max perk limit, feel free to change
		level.buy_slot_cost = 1500; //Cost of perk slot, feel free to change
		buy_slot_trigger = getent( "buy_slot_trigger" , "targetname" ); //Gets the trigger entity
		perk_bottle_model = getent("perk_bottle","targetname" ); //Gets the model entity
 
		playfxontag (level._effect["powerup_on"], perk_bottle_model, "tag_origin"); //Puts the powerup effect around the bottle
		self thread perk_bottle_rotate( perk_bottle_model );
 
		buy_slot_trigger SetCursorHint("HINT_NOICON"); //Gets rid of hand symbol 
		buy_slot_trigger UseTriggerRequireLookAt(); //Requires the player to look at the trigger to use it
		buy_slot_trigger SetHintString("Press &&1 To Buy Perk Slot [Cost: 1500]"); //Hint string players will see
 
		while(1) //Loops so players can use it more than once
			{
				buy_slot_trigger waittill( "trigger", player ); //Waits until player uses trigger
 
				if(player.score >= level.buy_slot_cost && level.perk_limit < level.perk_limit_max) //Checks to see if the player has enough points
					{
						player maps\_zombiemode_score::minus_to_player_score( level.buy_slot_cost ); //Subtracts the cost from the player's score
						level.perk_limit = level.perk_limit + 1; //Increases the player's perk limit by 1
						iprintlnbold( "You Can Now Hold " +level.perk_limit+ "/" +level.perk_limit_max+ " Perks" ); //Displays this message to the player
					}
 
				if(player.score >= level.buy_slot_cost && level.perk_limit >= level.perk_limit_max) //checks if the player has reached the max perk limit
					{
						return;
					}
			}
	}

perk_bottle_rotate( perk_bottle_model )
	{	
		self endon( "disconnect" );
		while(1)
			{
				perk_bottle_model rotateyaw( 360 ,2 ); //Rotates the bottle
				wait 2;
			}
	}

**PLEASE NOTE**

If you have Bam's BO perks in your map, make sure to go into _zombiemode.gsc and delete the level.perk_limit line in there. If you dont, it will cause bugs in the script.

I hope some people find this tutorial helpful, and please let me know if you encounter any problems.

Thanks to PROxFTW and Arceus for letting me know of syntax errors

Nice job man, I may use this

How would I have "Perk Limit: #" in the top left corner of the screen, like zombie counter style. Would it be a simple modification?

Thanks!

And here's a hud elem I put together:

Code Snippet

Plaintext

perk_hud_count()
	{
		PerkSlots = create_simple_hud();
		PerkSlots.horzAlign = "center";
		PerkSlots.vertAlign = "middle";
		PerkSlots.alignX = "Left";
		PerkSlots.alignY = "middle";
		PerkSlots.y = 230;
		PerkSlots.x = 60;
		PerkSlots.foreground = 1;
		PerkSlots.fontscale = 8.0;
		PerkSlots.alpha = 1;
		PerkSlots.color = ( 0.423, 0.004, 0 );


		PerkText = create_simple_hud();
		PerkText.horzAlign = "center";
		PerkText.vertAlign = "middle";
		PerkText.alignX = "center";
		PerkText.alignY = "middle";
		PerkText.y = 230;
		PerkText.x = -1;
		PerkText.foreground = 1;
		PerkText.fontscale = 8.0;
		PerkText.alpha = 1;
		PerkText.color = ( 0.423, 0.004, 0 );
		PerkText SetText("Perk Limit: ");


		while(1)
			{
				PerkAmount = level.perk_limit;
				PerkSlots SetValue(PerkAmount);
 
				PerkSlots.alpha = 1;

				wait 0.5;
			}
	}

Just put that after the buyable_perk_slot() function.

Then inside the buyable_perk_slot() function, add this:

Code Snippet

Plaintext

self thread perk_hud_count();

Directly under this:

Code Snippet

Plaintext

self thread perk_bottle_rotate( perk_bottle_model );

And you should be good to go

You'll have to mess with the hud elem positions though, I'm not sure what the xy values are for the top left of the screen. I'll see if I can figure them out and if I do I'll post another reply

				iprintlnbold( "You Can Now Hold " + player.perk_limit + "/" + perk_limit_max + " Perks" ); //Displays this message to the player
		}
	}
}

More efficient code.

Edit: Make sure somewhere on onPlayerSpawned you add self.perk_limit = (some_amount);

Thanks

I'm still learning so I didn't expect my version to be perfect lol

It doesn't set the perk limit to 4 so I can keep buying perks without the feature. How do you set a limit of 4?

Go into _zombiemode.gsc and add level.perk_limit = 4 right underneath maps\_zombiemode_auto_turret::init();

nah there is no limit check by default, and bam used a "level" limit, rather than induvidual players

Youd need to edit the function in zombiemode_perks.gsc ( I think its vending_trigger() )

Btw, nice work man

Edit: Make sure somewhere on onPlayerSpawned you add self.perk_limit = (some_amount);

i would also add this under where it defines "perk_limit"

Code Snippet

Plaintext

flag_wait( "all_players_connected" );
players = get_players();
for( i = 0; i < players.size; i++ )
{
	players[i].perk_limit = perk_limit;
}

and also change "play_no_money_perk_dialog()"
to "maps\_zombiemode_perks::play_no_money_perk_dialog()".
Because that function is only in _zombiemode_perks.gsc

Can anyone help me?
I have the "more efficient" part of the script along with the other scripts above it that are not included in the more efficient part. I have Bam's perks installed and I took out the level.perk_limit in my _zombiemode.gsc. When I load the map with it like I described, the perk HUD is there (It says perk limit = (no number), and it lets me buy all 8 perks without buying more slots, even though I can still buy the perk bottle. If I leave Bam's level.perk_limit in the _zombiemode.gsc It says perk limit = 4 on the HUD and the game limits me to 4 perks and I can buy slots but not more actual perks. Any help would be great!

Thank you, works well only it still allows me to buy more perks ~~but I fixed it~~
EDIT:
For some reason it still lets me buy after I thought I fixed it, I am using Bams perks and got them through Scriptplacer Z. I have searched for the level.perk_limit but haven't found it.

you havent made anychange to the trigger for the perk, thats why its not working

your setting a limit yes, but that limit is not being considered when buying a perk

you need to add a check into _zombiemode_perks on the triggers

These errors you guys are getting are odd to me. It may he because I added in Bam's perks manually, as I dont use script placer Z. That could be the problem...something with the script placer, because the script and everything I posted works 110% perfect for me ???
