Well its not that way. I dont know if you are fimiliar with a jumpbug in counterstrike. A JB is a duck+jump combination, when you fall down from a high distance, and you make a JB the HL1 engine dont register you hitted the ground. So you wont lose any damage.
You need to jump down and hold duck, when you are 4 units above the ground you need to release duck and at the SAME moment you need to press jump. At this time the engine wont register you hitted the ground. So you dont lose any damage.
Im making a jump bug map. Now, its easy to finish it. I made a killer to 1 hp. But when you have 1 hp you only have 1 try to make a jumbbug. And thats really hard. With 100hp, you got allot change because you just cant fall and do nothing. You only lose some hp. So the effect of a JB is gone.
When I place a teleport trigger, and you do a jump bug. The teleporter dont work, same as on the ground. The engine dont register the player hitting the trigger. Now one problem solved, but when you are done with the jumb bug. The engine begins to register the player again and you will get teleported.
Now, I need to find a way to disable the teleported after the jump bug. You are 2 units above the ground when you make a jb. But I cant find a right way. Maby a challenge for somebody?
