Undo Line Special

Tormentor667 · Post by **Tormentor667** » Fri Sep 05, 2003 9:13 am

Well, let's say I have given one line a walkover linespecial, which displays a text everytime you try to walk over it.

Now, I want, that this script is no more displayed, if I have executed a special script. How to do?

Two ways spring to mind.

Make the text line a line id (type 121 I think) and use an open script to set the line special to run the text script. Then when your special script executes, it has an instruction in it to either change or remove the special from the line that prints the messages.

or

Have the text script check for a variable. If false, print the text, if true print nothing. Have your special script change the variable.

Thx but I need the acs command to remove a special from a linedef

That's the mainproblem, sorry for not being clear enough

clearlinespecial(); will clear the special of the line that activated the script

SetLineSpecial(id, 0 /* nothing heh */);

I thought he wanted the line to be repeatable until the second script had been run because of this...

I usually use Hirogen2's way of clearing a line. If you want to clear multiple lines, either give them the same id, or just list them all in the script that is clearing the special.

eg
setlinespecial(1, 80, 10, 0, 0, 0, 0);
setlinespecial(2, 80, 11, 0, 0, 0, 0);

that sets up 2 lines (id 1 and 2) to run 2 different scripts (10 and 11). To clear them use:

setlinespecial(1, 0, 0, 0, 0, 0, 0);
setlinespecial(2, 0, 0, 0, 0, 0, 0);

Not sure if all the 0's are needed, but it works.

Thx, I'll try this

Just one more question: How can I set a wall impassible, blocking everything or normal by acs?

Post by **Enjay** » Sat Sep 06, 2003 8:17 am

You need to use Setlineblocking.

eg

Setlineblocking(200,BLOCK_EVERYTHING); //Block anything from crossing lines with id 200

Setlineblocking(200,off); //removes blocking from lines with id 200

You'll find the details here:

Sounds like you need ACS_ExecuteAlways.
No, the zeroes are usually not needed. ACS_Execute(script, map, arg1) also works if the script only takes one arg. Try.
