Welcome to the new board for Pulsar2D

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: [Select]

-- 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()
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.

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).

looks great 

[Cybermonkey]

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

[Osgeld]

so when's beta going to be out? 

[Cybermonkey]

I think the first version will be alpha.  But yesterday I implemented sprite animations with some improvements over the EGSL versions. I have to admit that the animation timer in EGSL is just an integer counting to the given value. In Pulsar2D it's a real timer which means if one specifies e.g. 50 the animation frame changes every 50 ms independently from the FPS limiter. Oh and another thing I want to add this evening: animaton loops. Just like in playsound, if one sets the loop to -1 it's looping forver, a 0 loops once, 1 loops twice etc. And another handy thing will be added: a start frame and end frame. So if a sprite consits out of several animations that's no problem anymore. For example like this one

[piradyne]

Looking good man. Keep coding!

Respect!

[Cybermonkey]

Thanks Jarrod. By the way, it came to my mind that my game engine should work theoretically with Game Pascal once both are finished ... 

[piradyne]

Hi, yes it should work indeed. I can't want to try it out and test the GP compiler in more complex situations. Cool man.

[GEEK]

Just saw that you misspelled "welcome" (Wlecome) :p
Still busy with the documentation of EGSL, but I have to work now to so please be patient...

I'm doing the best I can

Thanks, I corrected the mistake.
BTW, documentation for Pulsar2D will start soon. This time I will be using Markdown language so it's easy to convert it to all formats: odt, docx, pdf, html or even epub. 

[GEEK]

Ok, good to know, unfortunately I don't know a lot off html  so maybe I can't help...
Today I can work on the 'EGSL' pdf, I've noticed that there are a few shortcuts (mailed you about that) in the IDE
that are undocumented.

[Osgeld]

de 'EGSL' pdf, I've noticed that there are a few chortcuts (mailed you about that) in de IDE

I can't wait to attempt to read that   

[GEEK]

woops haha, I was tired,
my native language is Dutch, so I apologize for any grammatical mistakes,
I'm going to spellcheck "THE" pdf if i'm done no worries (;
