Hi,

I am trying out this water in my game:

but I get this error for some reason?

 

attempt to index global 'App' (a nil value)

 

on this line:

 

refractionbuffer = Buffer:Create(App.context:GetWidth(),App.context:GetHeight(),1,1);

 

can someone please help me?

 

Thank You!

Guessing you have a C++ project with this? The App variable only exists in a Lua application so this might have only been meant for a Lua app at the time of creation (standard edition probably wasn't even out at this time).

 

Can probably change it with Context:GetCurrent().

local context = Context:GetCurrent()

refractionbuffer = Buffer:Create(context:GetWidth(),context:GetHeight(),1,1);

 

So the context gets created in the App "class" in a Lua application and the App class is global to the Lua project so you can just do App.context to get it. However in a C++ project there is no App class so instead you have to use Context:GetCurrent() to get the current context in Lua, which in most all applications there is only ever one context anyway.
