 Re: Portal Map

I've been recreating a map I saw in Portal (new valve game), and I am having problems creating a crusher, well a brush with spikes on it that comes down from the ceiling slowly. I know how to put the spikes and so forth on, but I am having trouble finding out what entity I need to tie the initial brush to, and if it needs a special trigger, or just goes when the map starts. Any help would be greatly appreciated as I am really getting into mapping. If this is in the wrong section, please forgive me, I am new to the Snarkpit forums.

This should be in HL2 mapping questions.

but to answer your question, you could make the crushes a func_door. Build it in the down or "closed" position and set the door direction to "down" and check the box "start open"

then make a brush volume under the crusher and turn that into a trigger_once and have it activate the door.

You may also want to set a "lip" value which you can use to set how far the crushing brush should move. By default it will move the same distance as its own size, and a lip value sets how much LESS than that distance it should move. So if you set a lip value of 16, and the door/crusher/whatever is 64 units tall, then it will move 48 units down. Use negative lip values to make it travel further than its own length - e.g. setting -16 would make that same brush move 80 units from its initial position.

I would probably make a spiky brush a func_train and then just make the track starting on the cieling and going to the floor. Then you have a tirgger_once underneath it so when the player walks underneath it, it begins to lower. You can also have the trigger close teh door the player came into, or block off all routes except the one you want the player to go to.
