can some one explain how i make triggers?

Well, I presume you know how to create brushes.

1. Chose the tools/tooltrigger from the texture menue
2. Create a brush the size of your trigger, make sure the tooltrigger texture is applied to it.
3. With the select-tool, right-click on your brush in one of the sideview windows (not the 3D-view), and select "Tie to entity"
4. Your brush is now an entity. In the dropdown-list at the top of the properties-window, choose either trigger_once for a single-use trigger, or trigger_multiple for a multiple-use trigger.

In order to use your trigger, you need knowledge of Input/Output-systems, you can find more information about triggers, I/O, Hammer and the Source-engine on:

The Valve Developer Community

Really curious how you were able to make a blank post! --GLaDOS

i can't find the page on triggers

http://developer.valvesoftware.com/wiki/Trigger

ok, so how a trigger works is this.

1.You make your trigger, (a trigger once, to only be able to be 'tripped' one time, or a trigger multiple, able to be 'tripped' infinite tiems.)

2.You a)check flags for what you want to 'trip' this trigger,
b)if you need to, make and set a filter for your trigger.

3.Set its Outputs. (Use OnStartTouch if you want this trigger to send an output when a valid item touches it, OnEndTouch(All) if you want this trigger to send an output when a valid item, onendtouch, stops touching it, or when no more valid items are touching it, onendtouchall.)

I know this isn't the best tutorial, but the best way to learn Hammer, and its features, it to just make a small map, put a trigger in it, walk into the trigger, and tweak it until you figure it out and it works. Eventually, it'll just click, and you'll be like OMFGEEZUS!!! IGETTHISNOWWWWW!!!!!:DDDD

hope it helped,

You asked how to make triggers: Ricotez told you exactly how to do it.

You asked for the page on triggers: msleeper gave you the page on triggers.

And isnt that what you got in the second post of this thread?

You got the answer to your question - how to make a trigger, and where to find the page on triggers on the Valve wiki (which took all of 3 seconds to do a Search) - so keep your asshole attitude to yourself.

Locking this thread.
