How do I make objectives (specifically listed below)

[Crackit]

I have a map I'm working on and I need the survivors to bring back 4 batteries throughout the map.  I've decompiled a few maps, (not taking their ideas) but I couldn't really figure it out.

It'd be nice if you could list what I should do step by step.  Or at least give me a good tutorial elsewhere.

Thank you.

place four batteries. Make trigger_multiple. set it a filter, which allow trigger this entity only a specified things (your batteries). Set output to increase volume of some math_counter by 1 (make max value of this counter - 4, and add output which starts another part of objectives when hitmax). You may also add "kill - !activator" output, to remove bringed batteries, to avoid bugs. Or use trigger_teleport instead of.

Okay, it didn't really help me out to be quite honest.  I understand I have to make a trigger_multiple, and the Filter names, but everything else I'm abit clueless what to do next.

Alright, here's the deal.

If you want the batteries to stick, you need to do this:

Step 1) Make your 4 batteries and scatter them throughout the map. Name them all "battery".
Step 2) Make 4 more batteries and place them where the batteries will go. Once you have the position perfect, turn them into info_targets and name them "BattLoc1","BattLoc2", etc.
Step 3) Make trigger boxes around the locations. When a held battery touches one, it'll be warped, so don't make it too small or too large. Give them unique names and make them trigger_teleport.
Step 4) Make a filter for these teleports, letting only entities named "battery" through. On teleport, freeze the battery, turn off the trigger, and open a trigger relay.
Step 5) Once all 4 trigger relays are open, it means all batteries are in place and you're good to do what you want.


If these steps are unclear, too bad. Read up on these:
