new to forum and to the programing
« on: July 08, 2013, 10:12:47 am »
Hi I am new to this EGSL but so far I love it :)
but have also a few questions and also wish someone could help me with it :)
here it goes:
1.. I want to do camera(player) follow how do I do it????

2..I see keyboard action but to code it???  how can I tell the numbers for each key?
if keystate (275) then
   player.x=player.x+1
end
 how can I tell the numbers for each key? IF i want to use  like  ("d") or ("u") or any????

3..I come from (NOT PRO but in process )love and corona sdk  and they use also lua yay!  BUT I was able to use external modules functions.. now
how do you do it here? any tutorial as an advise???

4..once the game is done how can I compile it? so i can send it to any other pc or device or etc ?????

If someone could give me any type of clue ill be so happy :) so far IDK why but this program is nice  to use and i want to get
the opportunity to make a cool game :)

You can start by looking here ->http://egsl.retrogamecoding.org/documentation/

and http://egsl.retrogamecoding.org/

And also old forum very usefull -> http://retrogamecoding.org/forum/index.php?page=Index

some keys:

Code: [Select]
k_esc = 27
k_up = 273
k_down = 274
k_right = 275
k_left = 276

It is the same as SDL so the keys are the same, look thru the links I gave you and it is based on lua so you can do like in strict lua programming.

Using external modules is like in Lua. Let's assume you have that Lua script
Code: [Select]
function add (x,y)
 return x+y
end
saved as "adding.lua". Then put it in the same path as your main script. In your main script do
Code: [Select]
require "adding"and use the function as e.g.
Code: [Select]
add (5,9)or to see the result
Code: [Select]
drawtext (0,0,add(5,9))

If it is so easy, why it is not part of the documentation at all?

i have added the Keys into the EGSL Documentation in EGSL IDE for Haiku (Without SDL before).

Code: [Select]
Key Numbers
Like in SDL
K_UNKNOWN = 0;
K_FIRST = 0;
  K_BACKSPACE = 8;
  K_TAB = 9;
  K_CLEAR = 12;
  K_RETURN = 13;
  K_PAUSE = 19;
  K_ESCAPE = 27;
  K_SPACE = 32;
  K_EXCLAIM = 33;
  K_QUOTEDBL = 34;
  K_HASH = 35;
  K_DOLLAR = 36;
  K_AMPERSAND = 38;

thank you all wonderful answers :)

but Cybermonkey? :o

is it possible to  turn the  external function into a variable ?
----------------
new.lua
local t = 1
function try()
    t = t+1
end
----------------
require  "new"

local m = try()

Can I work  the variable like that???

sorry i am pretty new at this! I kind of played with corona sdk  for alil while so yea (wonder if  close to it?)

I'm not sure what you want to achieve, but the good news is that both things are possible. If you want to get a result from the function you need to pass value and then use return():

Code: [Select]
new.lua
local t = 1
function try()
    t = t+1
    return(t)
end
----------------
require  "new"

local m = try([value])

If you want to create an alias for the function, you shouldn't use ():

Code: [Select]
local m = try

Hope, it helps. :)
