[Trigger] Following Camera in height differences

[Zanna]

Hi Guys!
I need a trig allows camera follow the height differences of a unit. The problem born when my unit go on a higth walkable doodle like a tower, for the game is in the same level and the camera don't up.
Thanks a lot!

local unit u = yourUnit
local location l = GetUnitLoc(u)
local real z = GetLocationZ(l)

and then set the camera height to that variable. I am pretty sure it would work.

Also use the flying height.
Invisible platforms are a pain in the (_._) in this matter.

Thanks very much
but i don't have jass knoledge.
I have paste jass script but when i test, game don't le me start the map.
Could you show me a example of "camera heigth " as variable?
Please

• Camera - Set Player 1 (Red)'s camera Height Offset to (Current flying height of No unit) over 0.00 seconds

Replace "No unit" with your unit.

use custom scripts. One custom script per line and then put the action Wiet gave you just bellow it.

This is just about as GUI friendly as I can go. Just add an event and change the variable.

• Untitled Trigger 002
  • Events
  • Conditions
  • Actions
    • Custom script: local unit u
    • Custom script: local location l
    • Custom script: local real z
    • Custom script: local real fly
    • Set your_unit = (Triggering unit)
    • Custom script: set u = udg_your_unit
    • Custom script: set l = GetUnitLoc(u)
    • Custom script: set z= GetLocationZ(l)
    • Custom script: set fly = GetUnitFlyHeight(u)
    • Custom script: call SetCameraFieldForPlayer(Player(0), CAMERA_FIELD_ZOFFSET, z + fly, 1 )

I think that that function that I mentioned is already enough....
There is one problem where the unit is standing on an invisible platform where his flying height is 0 and the terrain height is still where the terrain ends instead of where the invisible platform is.

I read that standing on blizzard cliffs made the unit's flying height remained the same while the Z is actually above 0.

This was in a thread from like 1-2 years ago so I don't remember which one.

But if you also use GetLocationZ(), that will mean that your camera will be at double the height because the camera Z offset counts from GetLocationZ() of the targeted location.

For the first think thanks for the availability. ^_^
My unit is a Mur'loc, and i need to be amphibious, I don't want he walk on a tree...

If you want to be able to set the camera height to the exact height (or relative height) of the terrain, you will, apart from GetLocationZ(), also need a system that Bob666 made some time ago. Basically, warcraft uses some kind of weird interpolations to make the camera move smoothly across uneven terrain. What his system does is generate a camera map, which allows you to get the relative camera offset using a single function (if i remember correctly, it is simply called GetCameraZOffset). I don't have a link, but i know you can find it inside his FlightSim map.
