Hello my UDK Brother. Yeah, it is exactly this what I have done… I had saved hundred of old udk tutorials and this was one of them. However I dont plan doing the disguise with a box, no, I plan by carwling between grass. So whenever you are crawling the enemies wont attack you.
How I am doing this? Like I said before, keep things easy. I added a trigger volume in the size of the entire map, however I placed it some units above the ground, so that whenever the player is crawling, his body (which as a physics assets) won’t be touching the trigger volume.
So in the enemy kismet AI sequence, the fire sequence will work only if the player is touching the trigger volume. I know it is not perfect, but it works, and it feels like Metal Gear Solid.
That’s the matter, no need to be perfect, so long as it works and is fun!
