How to make moving stairs

Four easy steps to create moving stairs like in Portal.

Posted by on - Basic Mapping/Technical

Have you ever wanted to make stairs like in Portal for your level, but you never found out how? Well, in this little tutorial I'm gonna show you how to make some simple moving stairs (portal-like).

First step:
Make a couple of brushes that will form the stairs (size doesen't matter, but make sure to align the brushes on their corners). I made mine 192.0 x 32.0 x 8 (also, I made 8 steps for the stairs)

Step two:
Create a hole, in which the stairs will be hidden, and make sure they fit in there. TIP* When you usually go up the stair, you bump a bit (down-up).If you want to get rid of that, create a ramp on each step. Then make sure they connect to each other, so when the stairs are open they form a ramp. Make sure you use the "Player_clip" texture. Then tie each step including the ramp to "func_movelinear"(select the two brushes and click tie to entity, select fun_movelinear and then hit ok.

Step three:
Now, select each "func_movelinear" and open the properties. Change the names to:

• stair1_1
• stair1_2
• stair1_3
• stair1_4
• stair1_5
• stair1_6
• stair1_7
• stair1_8

Then, the move distance. The first step should have 15, second one 30, third one 45, fourth 60, fifth 75, sixth 90, seventh 105 and eighth 120. Finally, set the move direction to "up" (-90 0 0)

Step four:
Create a brush using the "trigger" texture and then tie it to "trigger_multiple". Open it's properties and name it "trigger_stair_open". Now, if you set the "delay before reset" to -1 it will only trigger once (that's what I did). After that, go at Outputs and add the following:

Make sure you write at delay in seconds, exactly this: The first stair should have 1.40, second one 1.20, third one 1.00, fourth 0.80, fifth 0.60, sixth 0.40, seventh 0.20 and eigth 0.00. By doing that, the stairs will open from the last to the first. If you want to make the open from the first to the last, inverse the numbers for each steps.

Step five:
Compile the map and ejoy your moving stairs.
