First Person Camera System:
Introduction:
Before reading this tutorial, please do not go “Ughhh not another tutorial on a first person camera system!!” (http://www.hiveworkshop.com/forums/...rials-279/creating-first-person-camera-93891/). I created a system that works for every player, does not lag (not that the other one on Hive does), has a map file attached, has animations playing so you look like you are actually walking to the other players and has some comments in the triggering to guide you.
What is a first person camera system?
To the people who don’t know, a first person camera system is like a first person shooter, making it look like you are looking through the eyes of the person you are playing as. They are great to use for a Warcraft 3 map because it makes your map more unique and exciting to play. But the disadvantages of using a first person camera are that it can not be used on a hilly surface (it goes through the ground and everything turns black), it can’t be used on a large unit (because you can see the inside of the unit’s body), and it makes picking up items harder.
The system:
Coming first is the most important trigger, the loop, then following that are the movement triggers and the attack trigger:
If you hold down the left/right/up/back arrow key it sets the boolean to true and if the boolean is true in the loop trigger your unit turns left/right/up/back. Once you let go of one of the arrow keys though, it sets the boolean of the direction to false deactivating the direction actions.
Up = Move forward
Right = Look right
Left = Look left
Down = Attack
Stopping your unit:
You may have seen that the camera unit can go through things and get out of the map, if you would like to stop the camera unit, put a solid unit/doodad in his way.
End:
You don’t need to give credit for the system (credit is appreciated) and I hope you have a good time using it for your map (I believe there should be more first person games out there). Document is at the bottom.
System in use (It's the same system but it's on a different testmap and is combined to my reload system because i'm going to use this for my other current project):
Update 1: Fixed every error Maker pointed out.

You however say my system lags? The movement of you camera is smoother if that's what you mean, I wouldn't call it lag. And can be used by everyone? I don't see how my system can't be used by everyone :\ Also, I had a map file attached, but it was deleted cuz it was actually an unfinished map the system was used in.
