Here is an example showing a direct contrasting example of the two Lua objects.
In Jam's, I can't get Lua functions to accept parameters.
In Vortex's, I can.
Maybe I'm doing it wrong, but I don't think so.
This is not to say Jam's Lua+ is inferior. I'm actually hoping it's superior in other ways, since I'm having some more advanced crashing issues with Vortex's.
I wish to test Jam's in such more advanced conditions, but I'm getting stuck with this basic feature of passing parameters to Lua functions not working, so it's hard to test advanced things.
Here's to hoping this issue will be fixed soon.
