Portal Challenge Script

First Step

Note:You will need to obtain GCFScape for this step.

• Launch GCFScape and open portal content.gcf in your SteamApps folder.
• Extract the file portal/scripts/challenges/challenges.bns and put it into Steam/SteamApps/your_account/portal/portal/scripts/challenges
• Now, open the bns file with your favourite text editor.

Inside the file

• When you open the challenges.bns file you can see scripts similar to this one:

"#Bonus_Map_TC13Challenges"
{
	"map"		"testchmb_a_08"
	"chapter"	"chapter5.cfg"	[$X360]
	"image"		"bonusmaps/testchmb_a_08_challenges"
	"comment"	"#Bonus_Map_ChallengesComment"
	"lock"		"1"

	"challenges"
	{
		"#Bonus_Map_ChallengePortals"
		{
			"comment"	"#Bonus_Map_LeastPortalsComment"

			"bronze"	"9"
			"silver"	"5"
			"gold"		"4"
		}
		"#Bonus_Map_ChallengeSteps"
		{
			"comment"	"#Bonus_Map_LeastStepsComment"

			"bronze"	"30"
			"silver"	"20"
			"gold"		"10"
		}
		"#Bonus_Map_ChallengeTime"
		{
			"comment"	"#Bonus_Map_LeastTimeComment"

			"bronze"	"40"
			"silver"	"30"
			"gold"		"19"
		}
	}
}

"#Bonus_Map_TC13Challenges"

This piece of code denotes the name of the map. This is linked to the portal_yourlanguagehere.txt file in the game's resources folder. Note that this is language specific, and unless you plan to make your map multilingual, you can simply replace it with a string.

"map"		"testchmb_a_08"

This is the name of the map without the bsp extension, the one which you put in the game's maps folder.

"chapter"	"chapter5.cfg"	[$X360]

This line refers to the chapter the map belongs to. You can find these chapter files in your GCF file. Simply create a new chapter with any name and a cfg extension. Add a line for each map in your chapter in to the file in this format:

map	your_map_name

Now, put this cfg file into the steam\steamapps\your_account\portal\portal\cfg folder.

"image"		"bonusmaps/testchmb_a_08_challenges"

This is the thumbnail of the map, which is in fact a material. The root path for this is steam\steamapps\your_account\portal\portal\materials\VGUI.

"comment"	"#Bonus_Map_ChallengesComment"

A language based description of your map. Again, unless you want to make the map multilingual, just replace it with a string.

"lock"		"1"

A boolean variable, which specifies if the map is locked or not until you complete the game.

Challenge types

You will also have to set the criteria of your map for

• Portals
• Steps
• Time

There are three similar sections at the end of each map. This one below is for portals. For steps or time, replace the "Portals" in each string with Steps or Time, accordingly.

"#Bonus_Map_ChallengePortals"
		{
			"comment"	"#Bonus_Map_LeastPortalsComment"

			"bronze"	"9"
			"silver"	"5"
			"gold"		"4"
		}

The first line, again, is a language-based string variable. You don't have to change it here. The following three lines specify the amount of Portals, Steps, or Time needed for each medal.

Adding your own challenge

Adding your own challenge is an easy, 3 to 4 step task.

• Make your map(s) and put them in Steam/SteamApps/your_account/portal/portal/maps
• Create a cfg file containing a line for each map which reads map map_name and put the file into the Steam/SteamApps/your_account/portal/portal/cfg directory.
• This is an optional step as you can reuse an old image, or create your own. If you created your own image, put it into the Steam/SteamApps/your_account/portal/portal/materials/VGUI directory or one of its subdirectories (recommended).
• Finally, create a new .bns file in the Steam/SteamApps/your_account/portal/portal/scripts/challenges folder and edit it with or without the help of this tutorial.
