How do add levels to game template? Sorry, real newbie here.

ar2rsawseen · April 2012

You have a packs.json file, where all packs or game modes are defined and each one has a "level" property, which defines how many levels are there in this pack.

First of all thanks.

That part i get, but how do a link them to the levels i create. It alwais opens level file, how do a link to others files? Like level_1_1, level_1_2?

Got it.
It was so easy. Thanks...

@ar2rsawseen

How do I add level info directly into the packs.json? For every level I have a different spawn table, which I save directly on a .lua table file like this:

self.levelSpawnData = {
	{ {1,2000}, {1,1000}, {2,0}, {1,1000} },
	{ {2,1000}, {2,1000}, {2,2000}, {2,2000} },
        { {2,1000}, {1,1000}, {2,2000}, {2,0} }
}

Each line is a level and each row is a different enemy with a spawn time in milliseconds. I think it would be better to put that in packs.json, but I don't know how it's syntax works.

{"packs":[
{"name":"Intro pack","levels":6},
{"name":"First pack","levels":20},
{"name":"Second pack","levels":20},
{"name":"Third pack","levels":12}
]}

What I want to do is: on "levels" instead of specifying how many levels there are, put the levelSpawnData table there. Please help me out.

I managed to make it work with something like this:

{"packs":[
  {"name":"Intro pack","levels":[
    {"level":[
      {"type":1,"time":2000},{"type":1,"time":1000},{"type":2,"time":0},{"type":1,"time":1000}
    ]},
    {"level":[
      {"type":2,"time":2000},{"type":2,"time":1000},{"type":1,"time":0},{"type":1,"time":1000}
    ]},
    {"level":[
      {"type":1,"time":2000},{"type":2,"time":1000},{"type":1,"time":0},{"type":1,"time":1000}
    ]}
  ]},
  {"name":"First pack","levels":[
    {"level":[
      {"type":2,"time":2000},{"type":1,"time":1000},{"type":2,"time":0},{"type":1,"time":1000}
    ]},
    {"level":[
      {"type":1,"time":2000},{"type":2,"time":1000},{"type":1,"time":0},{"type":1,"time":1000}
    ]},
    {"level":[
      {"type":2,"time":2000},{"type":2,"time":1000},{"type":1,"time":0},{"type":1,"time":1000}
    ]}
  ]},
  {"name":"Second pack","levels":[
    {"level":[
      {"type":1,"time":2000},{"type":1,"time":1000},{"type":2,"time":0},{"type":1,"time":1000}
    ]}
  ]},
  {"name":"Third pack","levels":[
    {"level":[
      {"type":1,"time":2000},{"type":2,"time":1000},{"type":2,"time":0},{"type":1,"time":1000}
    ]}
  ]}
]}

Each pack has several levels, each level has several enemies, each enemy has "type" and "time". I tested it and it works. The only problem could be when I put 50 or more enemies on each level.

Hi @somezombiegm

{"packs":[
{"name":"Intro pack","levels":6},
{"name":"First pack","levels":20},
{"name":"Second pack","levels":20},
{"name":"Third pack","levels":12}
]}

Defined above you could use an editor worlds, as Tilemap, for deploying everything that will contain the level easier.
Here is official source, for loaded worlds, you've created with Tilemap
https://github.com/gideros/Isometric-Tilemap

somezombiegm · May 2014

Hey @HubertRonald

At first I didn't think Tilemap would be necessary. Because my character doesn't walk through a stage, but there are many enemies appearing constantly. I'm gonna check that link, thanks!

HubertRonald · May 2014

Hi @somezombiegm

It all depends on what you want to do, for example for my app, Paint pong I do not use the tilemap as you.

Well I think you can also take advantage of the tilemap to create small puzzle

somezombiegm · May 2014

I've decided not to go with tilemap, cause it's just for the enemy spawn info. I'm gonna store the values on tables.

Good choice

somezombiegm · June 2014

@HubertRonald I'm having a lot of enemies and a lot of options for them, and my tables for them are getting to big. I want to use a tilemap but I don't want to use the packs.json option cause what I want is to design the levels easily. Something like these:

000000000000000020000000000000
000101001000100000000000000000
000000000000000020000000000000
000002002000003000000000000000
000000000000000000000000000000
000000000000001110000000000000
000000000000001000000000000000

The 0 are empty spaces and the other numbers are different enemies. How is that done? do I have to save that into a .txt file? Is that a good option for an android game? Should I save it on another file type?

HubertRonald · June 2014

Hi @somezombiegm
For your case, I would do the following

-- name file: 
-- Stage4of36.lua   for example
 
-- after inside your file (Stage4of36.lua)
return {
000000000000000020000000000000
000101001000100000000000000000
000000000000000020000000000000
000002002000003000000000000000
000000000000000000000000000000
000000000000001110000000000000
000000000000001000000000000000
}
-- with commas numbers

in your engine game you would have than load for example "Game/Stages/Stage4of36.lua"

engineGame = Core.class(Sprite)
 
function engineGame:init()
--[[
It dependent of where you've your file in your project
(numbers 4 (world) and 36 (level)
(you could have only levels in your game)
you should implement them with
 data.save and a global variable like "sets" in your code
 but you'll have that define each file stage1fo1.lua, stage1fo1.lua,...)
]]
 self.infoLevel = loadfile(table.concat{"Game/Stages/Stage",4,"of",36,".lua"})() 
--*
--*
 
 self:deployFoes()
 
--*
--*
end

To implement the enemies my suggestion is that you you elaborate a master class that contains all its properties:

foes = Core.Class(Sprite)
 
function foes:init(index)
--*
--*
end
 
--other functions

So all you could summarize it as follows

function engineGame:deployFoes()
 self.foesGame={}
 for i=1, #self.infoLevel do
  if self.infoLevel[i]~=0 then -- I suppose than 1,2 and 3 are enemies
    self.foesGame[#self.foesGame+1] = foes.new(self.infoLevel[i])
    --[[
    if you had implemented a camera class otherwise
     self:addChild(self.foesGame[#self.foesGame])
    ]]
    self.camera:addChild(self.foesGame[#self.foesGame]) 
end

But as I said you, all depends on what you want to do, this is only a possible solution, there may be other.

I want to use a tilemap but I don't want to use the packs.json option cause what I want is to design the levels easily.

This is not necessarily true, you can use tilemap without than you use packs.json, as I mentioned, it all depends on what you want to implement and most importantly how you feel comfortable, as long as this doesn't affect performance of your code.

@HubertRonald Thanks for the response. Something like that is what I'm looking for, I will work on it as soon as I can and come back if I get stuck or something LOL.

somezombiegm · July 2014

@HubertRonald I don't know how loadfile works, but I put the level info on a new file like you said and called it waveTest.lua and got this error message:

waveTest.lua:3: '}' expected (to close '{' at line 1) near '000101001000100000000000000000'

petec · July 2014

The message is telling you that you opened a curly bracket in line 1 but not closed it.

somezombiegm · July 2014

Yeah, it can be fixed by separating each line with a comma. But I wanted to know what HubertRonald was recommending me to do.

many thanks, it's useful for me!
