"Can't open scripts/classr" error

[VeTaL]

This error appears after last update of Leadwerks, but i'm not sure that its the main reason as i test it also on clean 2.4 version (that is without latest update)

 

So, somewhere on this forum, i found Josh's post about sources of enabling LUA in C++.

The code, posted by Josh is

       // Game loop

               if( !AppSuspended() ) // We are not in focus!

                       TurnEntity( mesh, Vec3( 0.5f*AppSpeed() ) ) ;

                       // Update timing and world
                       UpdateFramework();

                       // Render
                       RenderFramework();

                       // Send to screen
                       Flip(0) ;
               }
       }

       // Done
       return Terminate() ;
}

 

I saved it into Templates folder so i'm able now to quickly create base for new game.

But today i had error and looking like there are some troubles with LUA: i cant see environment_atmosphere

It looks like you are missing the Class.lua script. Did you copy the Scripts folder to your game's working directory?

[VeTaL]

macklebee, you're the best )

 

Maybe its a good idea to create FAQ from this simple questions?

[macklebee]

Its just one those things to be aware of if you are using the LE lua scripts in your game. I believe its due to the fact that abstract paths do not work in the lua command 'require()'. This is one of the things first mentioned when LE2.3 first came out and there have been other posts asking this as well in the past. I do not know if it is or not, but I would think that Aggror probably mentioned this in the user's guide as well.

[gamecreator]

Thanks from me as well. Just came across this and was so glad the answer was here.

[Scott Richmond]

Just wanted to pipe and say I just hit this problem as well. Thanks for the fix notes.

[VeTaL]

I think again about FAQ creation.

Maybe, when i would have some free time, i'll do that.
