How do I check if the camera is underwater?

I know it's possible, as the game has underwater ambient sounds.
However, even after searching every file (yes, even in the game engine) I have not been able to figure it out.
The only finding was in lua/ge/extensions/core/sounds.lua:

Code:

      local camObj = getCamera()
      camObj = (camObj and Sim.upcast(camObj)) or camObj
      globalParams:setParameterValue("g_CamFree", commands.isFreeCamera() and 1 or 0)
      globalParams:setParameterValue("g_CamUnderwater", (camObj and camObj:isCameraUnderwater() and 1) or 0)

It seems to be using a isCameraUnderwater() function, however I am unable to call it.
This command:

Code:

      obj:queueGameEngineLua("local camObj = getCamera() if (camObj and camObj:isCameraUnderwater() and 1) then camIsUnderwater = true else camIsUnderwater = false end")

Results in:


Oh, and I have not found the function isCameraUnderwater() anywhere other than in sounds.lua

 

Idk maybe use this code

Code:

camObj = (camObj and Sim.upcast(camObj)) or camObj

This code has been used in the sounds.lua but not in yours, so probably it's the problem

Also, why you used obj:queueGameEngineLua in your code?

 

That did fix it, thanks!

To execute the code in the game engine, as I cannot access the core stuff from the vehicle lua.

Alright, so I got it to work!

The command to check if the camera is underwater is:

Code:

obj:queueGameEngineLua('local camObj = getCamera()   camObj = (camObj and Sim.upcast(camObj)) or camObj   if (camObj and camObj:isCameraUnderwater() and 1) then be:getPlayerVehicle(0):queueLuaCommand("camIsUnderwater = true") else be:getPlayerVehicle(0):queueLuaCommand("camIsUnderwater = false") end')

camIsUnderwater is set as a global for use in the vehicle.
