Control camera FOV with keys [LE2] [Solved]

[omid3098 10]

Hi. I am trying to control camera FOV using two keys in Lua (to increase and decrese) but I cant access to main Camera FOV.

 

I have a CameraManager node in the scene and the code is something like this:

 

require("Scripts/class")
require("Scripts/constants/keycodes")
require("Scripts/hooks")

local class=CreateClass(...)

function class:CreateObject(model)
function object:DHook()
if KeyDown(KEY_U)==1 then
CameraZoom(45.0) -- or what? how should I use CameraZoom? 
end
end
AddHook("Flip" , object.DHook )
function object:Free()
RemoveHook("Flip" , object.DHook )
self.super:Free()
end
end

 

there were CameraZoom(cam,value) in the forum but I dont know what is cam or how I can create that to use Camera zoom. actually tried cam=fw.main.camera but that is for framework I think.

 

I did not write other parts of this code and also I don't have access to our programmer.

and I'm not dump

thanks before

I'm assuming you guys are using the framework class:

Ok. I'm a dump.

would you please describe more?

CameraZoom is only for C and C++ and there is nothing for LUA.

 

I just have to open Editor and edit some LUA codes to play with camera and do some trailer.

 

 

Edit: this code gives "Malformed number near 0.5f" error.

CameraZoom(camera, 0.5f)

You do not need to include the 'f' in the float value.

[omid3098 10]

it says value at index (1) is not an object

Your programmer is going to have to do this. I can't debug a program with one line of code.

[omid3098 10]

Programmer is doing bugfix since more than 2 months and I don't have permission to access him.

 

this is my CameraManager.lua:

require("Scripts/class")
require("Scripts/constants/keycodes")
require("Scripts/hooks")
local class=CreateClass(...)
function class:CreateObject(model)
local object=self.super:CreateObject(model)
--object.cameraFOV = CameraZoom(camera,1.0)
SetFarDOFRange(2,5)
SetFarDOFStrength(1)
SetFarDOF(1)
function object:DHook()
 -- Test if keys are working
 if KeyDown(KEY_U)==1 then
  SetFarDOF(1)
 end
 if KeyDown(KEY_Y)==1 then
  SetFarDOF(0)
 end
end
AddHook("Flip" , object.DHook )
function object:Free()
 RemoveHook("Flip" , object.DHook )
 self.super:Free()
end
end

 

I can enable/Disable DOF with keys but I have no Ideas how to access camera FOV.

now it works using this code:

require("Scripts/class")
require("Scripts/constants/keycodes")
require("Scripts/hooks")
local class=CreateClass(...)
function class:CreateObject(model)
local object=self.super:CreateObject(model)
function object:Update()
 if KeyDown(KEY_UP)==1 then
  CameraZoom(fw.main.camera,0.5)
 end
 if KeyDown(KEY_DOWN)==1 then
  CameraZoom(fw.main.camera,1.0)
 end
end
function object:Free()
 self.super:Free()
end
end
