Trigger or Code?

Make it so that when a certain NPC gets killed, a hidden trap door opens. Also to make a button open a hidden trap door. Thanks.

Well, to make a button open a hidden trap door, just use the func_button stuff to open a section of wall textured the same as the rest of the wall.S:SCan't help with the NPC's though, I mostly do CS:S

awsome thanks :smile: . now i just need the npc death triggering the door answer...

edit: wait...for the button i can make the door look like the background with textures, but how can i make it so that if you walk up to it it wont open. i only want it to open when the button is hit....

If you go to the flags tab for the door, there will be a box for "Touch Opens" As long as that box is unchecked, and you should uncheck "Shoot Opens" too, but as long as those are unchecked, the door will not budge unless the button is hit.

thanks sooo much :biggrin:

now can someone tell me how to make the trapdoor open once a certain npc dies?

thanks.

I'm sure if you fiddle around enough with the input/output tags then you could come up with something, unfortunately I don't know.

Here is my wild idea, but since I don't know how NPC's work it is probably totally wrong;

Name the NPC like NPC1, and then make it like open door when trigger_hurt I don't know it worked in my head. Never mind.

i think it would look better if you had 2 door halfs on hinges that are
contrained together for a trap door, then when you press button the
constraint is broken - and the two doors swing down realistically
utilizing that awesome physics engine that valve gave us, do what you
want but i think this would look much cooler.

Npcs have an "OnDeath" output that fires when they die. So for that NPC, add an output:

Output: OnDeath

Target: name of trapdoor

Input: Open
