Cybermonkey:
Yes, it's time to reveal the name for my next Lua interpreter and Free Pascal game engione based on SDL2: Pulsar2D
I just finished the Lua bindings with the so far implemented functions. Here you can se the somewhat comprehensive list:

A lot of things have changed, a lot have kept the same. Still missing are sprite animations and particles. These are the next things I wil implement, I just wanted to be sure that the rest is working as expected.
Here is the first example code in Lua:

--- Code: ----- first test of Lua bindings to Pulsar2D
require "scancodes"

win=openwindow ("First Test",-1,-1,1024,768)
setactivewindow (win)
setframetimer (250)
image = loadimage ("media/sprite.bmp")
sprite = createsprite (image)
freeimage (image)
x= 150
y= 250

repeat
key=getkey()
cls()
  color (255,255,0,255)
  fillcircle (612,356,50)
  drawtext ("Hello and welcome to Pulsar2D",10,10)
  drawsprite (sprite,x,y,2,2,0,false,true)
 
  if keystate (SCANCODE_LEFT) then
      x=x-1
  end
  if keystate (SCANCODE_RIGHT) then
      x=x+1
  end
  if keystate (SCANCODE_UP) then
      y=y-1
  end
  if keystate (SCANCODE_DOWN) then
      y=y+1
  end
   sync()
until key == SCANCODE_ESCAPE

freesprite (sprite)
closewindow (win)
closeapplication()

--- End code ---
With the scancodes.lua one needn't to remember all those numbers. If you want to check the escape key just use SCANCODE_ESCAPE (of course you can use the number if you prefer that but since these are now scancodes they are different from the EGSL keycodes).
A nice thing is that all error message are now inside a message box, so if you type the wrong filename for example... see the attachment.

Osgeld:
looks interesting, thanks for your efforts

regarding the scancodes, would it be a big deal to just embed them, nothing that EGSL runs on currently requires non pc keyboard scancodes (IE adb based MAC)?

Cybermonkey:
Well, as I said you don't need to use the scancodes from scancodes.lua. Just use the numbers instead (you don't have to include scancodes.lua then). But the numbers changed, so better look into the file first. For example escape has the number 41 (used to be 27 on EGSL).

GEEK:
looks great  ;D

Cybermonkey:
Thanks.
On Windows the messageboxes have a native look btw:
