In some fps games I have played, you cannot open certain doors until an area in the current level has been cleared of all enemy characters. This is a solution in fpsc.

You will need to select a character and change their fpe file so I suggest making a copy of it and (if it exists) the bin file. Use the copied fpe file in the following process. When you view the entities in the map editor, you should see the copied character available for selection.

Using Wordpad to edit, add the line ifused = box to a characters fpe file in the ;ai section. Box is an entity we will use for a 'counter'.

In this example, I am going to use 3 copies of the same character.

Add the 3 characters to a game and change the destroy script to destroyandactivate.

Add a box entity to the game and change the name to box. Make sure you cannot use or destroy the box. It needs to be dynamic and zero strength (indestructable). Probably does not matter too much about it being movable but also ensure the name of the box is unique.

Add the following script to the box as its Main AI:

desc = Counter

;Triggers

:activated=1:incstate=1,activate=0
:state=3:activateifused=1

;End of Script

Change the IfUsed parameter to Door.

Add a Door to the level and ensure its main ai is doorremote and its name is Door.

When you shoot the 3 characters, the door will open.

You can do this for more characters. For 5, ensure the box script has state=5 in place of state=3.

This does open more ideas (and not just doors!) maybe have a key or weapon upgrade appear.

Also it could speed games up. Only allow progession (and more characters to spawn) once an area has been cleared.

First off, I haven't tried this but if if you say it works, then it's brilliant. You have somewhat gotten around the lack of useable variables by using incstate. Very nicely done.

I normally use a light to assign the AI Main script to because it can't be used or destroyed, and can be placed outside, above or below the accessible area of the map.

Thanks for sharing this.
Best.

(NOTE: this should be made into a graphical tut and posted in the proper tut sticky)

I'm sorry, my answers are limited. You must ask the right question.

Tried it with 3 enemies in small map then 5. I have just added the process to a game I am working on. All works fine.

If you save away all the characters files (fpe and bin) then once the game has been built and completed, put back the copies for your next game.

Of course, you do not have to use a box...any alternate entity will do. Just make sure its dynamic and you have the ifused set to its name in the characters fpe.

Also the Door can be any name as long as this name is used in the process I described.

Yep. Initially I thought of using a light, but there is no IfUsed option on a light.

Again, great find and it opens up a few more possibilities, like having to collect so much money or pick up so many items. Another twist to the store idea.....

Thanks.

I was kidding I hope you realise. Of course your name will be there, this also goes for anyone else that sends anything in (which they haven't ) your name will be there.

Made another tweak to the opening text. It's better to make copies of a character and use that in the open door/object appear process.

Copy the characters fpe and if it exists, the bin file. The copied character should be available for selection when viewing the fpsc Entities.

Excellent TZap !! it works and is very useful.
Now tell me in which "manual" can anyone read about script language so as to do what you have done?
Like adding another line in an .fpe script?, etc.
And then when I asked how can one learn the intricacies of the language I have the very inspiring answer: See the FPSC manual or it is a simple if-then-goto language !!!!!!

Thanks a lot! I would advise against changing a characters fpe script unless you make a copy and use the copy.

Search the forums. If you need a script you can probably find one on here. I have found a lot!
