Lua for TIC80

tables

squares={1,4,9,16,25,36,49,64,81}

function TIC()
 cls(0)
 for i=1,#squares do
  print(i,i*16,0)
  print(squares[i],i*16,10)
 end
end

Lua tables can also be like python dictionaries (and javascript objects)...

PLANE={
 START_FUEL=2000,
 MAX_FUEL=4000,
 FUEL_INC=1000,
 FUEL_BAR_W=50
}

Tables can be *nested* (one inside the other)...

LVL={
 {
  name="1-1",bg=2,
  palor={},
  pkstart=8,pklen=3,
  mus=BGM.A,
 },
 {
  name="1-2",bg=0,
  palor={[8]=0x102428},
  pkstart=11,pklen=2,
  mus=BGM.B,
 }
}
