My Videos - Inspirations / Tutorials

Ninjadoodle · December 2017

Hi guys

I've finally gotten around to starting a regular YouTube Vlog. My plan is to make videos focusing on my inspirations when it comes to game design, Gideros tutorials, updates on my latest games, balancing sitting in front of the computer and exercise, some random rants, and behind the scenes family stuff.

I'll be doing my first tutorial (Gideros Hello World), in a day or two, and after that I would like to start posting one every week.

If you guys are interested, here is a little bit about me ...

... and here is one about the first game I've ever played, and the reason I make games today.

I'll post the any new tutorials / inspiration vids to this topic as I make them.

Thaaaanks

PS. Eventually, I would LOVE to do some Gideros creator interviews / spotlights.

Great to hear more about another Gideros dev. I could see Gideros in the background there.

Subbed!

Mike Townsend (the creator of Saboteur 2) has a few mutual friends with me on FB, you should contact him re your video: https://www.facebook.com/profile.php?id=100010743494629

Great stuff @Ninjadoodle, look forward to more

Ninjadoodle · December 2017

Hey guys, thank you all for the comments and subscriptions! It would be cool to create a thread, where developers share their Youtube channels. There are a couple of you that I've just subscribed to, as I didn't realise that you had a channel

@SinisterSoft - That's awesome! Thanks for letting me know about that

I will definitely send him a message. Must be weird having someone contact you after 30+ years telling you how much their game has impacted them lol.

SinisterSoft · December 2017

@Ninjadoodle - great idea. I've made a thread just for this:

Ninjadoodle · December 2017

Hi @SinisterSoft - Cool thanks! It will be fun to see what people post

Ninjadoodle · December 2017

Hi guys

The first of many planned "Geeking with Gideros" videos is up

This one is just a basic intro and "Hello World".

@Ninjadoodle Really liked the style of the video.

main.lua is usually loaded last as far as I know.

antix · December 2017

@Ninjadoodle my god man... you need to be using TexturePacker!!!

You should also try disabling that smartscreen / user access control crap. Generally when a program takes ages to load it is because UAC is doing dumb stuff, or the computer is having trouble connecting to the smartscreen internet service to check whether the executable is marked as "okay to run" by microsoft.

Disabling that stuff makes you less secure but really it's microsoft winblows so you are already rather unsecure by default 8-X

If you have this issue a lot we could do a Skype session and I could remote in and see if I can find out why it's doing that. Nothing more frustrating than a slow machine! You can also grab a 240GB SSD nowdays for around $150NZD so I'd recommend upgrading

Great video anyway, look forward to more :bz

hgy29 · December 2017

@Ninjadoodle, really great video! I can't wait for the next one.

Ninjadoodle · December 2017

@SinisterSoft - Thanks for letting me know! I will fix that up in the next video

So, if my understanding is correct the main.lua file is the file needed as the base of the project, BUT there are other files that load before it ... like init.lua, config.lua, and any classes.lua / level files you might have etc. This is to ensure that everything is ready for the main.lua file to use, when needed.

Is this more or less correct? I just wanna make sure I have the correct info, so I can can talk about it in the next vid

@antix - I am actually using Texture Packer (by Code & Web). What I was meaning is that I haven't used the one that comes with Gideros

I will definitely follow your tips about the 'Smart Screen' stuff. Thanks for the tips, I really appreciate it!

Lua Files and Execution Order

We can assume that the order of execution is pretty random, but there are two things guaranteed:

init.lua will always be executed first
main.lua will always be executed last
So the best practice is:

- to add all additional functionality and modifications to existing classes in init.lua
-do all initialization of app etc in main.lua (when all other code was already loaded)
-wrap the code in any other lua file in a scope as function
Yet better create each lua file as a separate Gideros class, either it will be a scene shown in scene manager or some simple object represented by class, but there should not be some plain code executed in these files, only in main.lua

Of course, all can be configured

Before an Gideros application starts, all Lua files at asset library are executed one by one. So it is possible to arrange the order of execution by setting the code dependencies between Lua files.

If you right click a Lua file and select “Code Dependencies…” from popup menu, “Code Dependencies” dialog opens:

Hi @oleg

Thanks for the link, that explains it nicely

I'll make sure to correct myself in the next vid!

Ninjadoodle · December 2017

Hi guys just put up a new video talking about the past week - if you’d like to see a little preview of my game, you can skip to 4.40

I’m really exited to almost have this done, as this will be my first non flash or HTML5 only game. Really hyped to finally publish something on devices.

Here is my attempt to explain retina and multi resolution assets.

@Ninjadoodle, cool stuff man. I wonder if your son will always remember how at just 2 years old he managed to blow out those candles... all by himself

So any reason you don't just run your game in the Gideros Player and record the window? It would look way better than the camera pointing at your cellphone

I got myself MovAVI Screen Capture Studio which was pretty cheap but works. It has a few crap bits but overall lets me record directly from the Gideros Player and I can then slap them onto my YouTube channel.

Man that drink looked way nasty! We have given up drinking "Infant Bovine Growth Serum" in our house and have adopted Soy Milk. We tried a bunch and found Pams Regular Soy Milk (from Pak'n'Save to be one of the cheapest and frankly best tasting ones out there. If you really need a little sugar you can put a little Milo or drinking chocolate

So with your game have you given any thought to adding some background behind what's happening onscreen? or do you think that might detract from the game too much? I was thinking maybe just some 1-bit seamless textures that you could place there with random colors.

Also with the goal that you meet to complete the level (at the top of the screen). Could that be more like divided into 7 (if the goal was 7 things) that lit up?

Anyway, looks cool and look forward to seeing the whole thing (even though those games make my puny brain hurt) :bz

keszegh · December 2017

@antix, @Ninjadoodle, for screen capture i'm using https://obsproject.com/, it's free and pretty dependable.

oleg · December 2017

In the google play game, you can record video games right from the tablet's screen

Ninjadoodle · December 2017

Hi guys

@keszegh @oleg @antix - Thanks for the tips, I will try he different software you've pointed out

@antix - Yeah he had a bit of help didn't he lol. The drink was interesting - like pea / bean mash with sugar haha. Thanks for the input on the game - I will definitely look into adding some sort of background. Also, the quota bar at the top is a bit tricky, as the goal is always different. Currently I just divide the length of the bar into whatever the goals is. What I would have to do (which would work), is to make little graphic dividers and place them at the correct distance, depending on the goal.

Thanks again!

antix · December 2017

@Ninjadoodle, hit me up if you need any assistance man

I couldn't see from the video that the line was divided. In theory you could just use a bunch of pixel objects...

Segments = Core.class(Sprite)
 
function Segments:init(options)
  -- default options
  self.segmentGap       = 4
  self.segmentHeight    = 8
  self.segmentColor     = 0x1122aa
 
  -- set user options
  if options then
    for key, value in pairs(options) do
      self[key]= value
    end
  end
end
 
-- create a number of segments
function Segments:populate(count)
  local floor = math.floor
  local gap = self.segmentGap
  local color = self.segmentColor
  local h = self.segmentHeight
  local w = floor(application:getContentWidth() / count) - gap
  local x = 0
  for i = 1, count do
    self:addChild(Pixel.new(SEGMENT_COLOR, 0.25, w, h))
    x += (w + gap)
  end
end
 
-- remove all previous segments
function Segments:clear()
  local numSegments = self:getNumChildren()
  if n > 0 then
    for i = numSegments, 1, -1 do
      self:removeChildAt(i)
    end
  end
end
 
-- make the specified segment fully visible
function Segments:illuminate(index)
  self:getChildAt(index):setAlpha(1)
end

@Ninjadoodle Technically (on export) all the lua files are loaded together into one big file. That's why you have to right-click and deselect the files that you use the 'require' command for.

Ninjadoodle · December 2017

@SinisterSoft - cool that makes sense, thanks for the tip

SinisterSoft · December 2017

Looked at your game - reminds of the warioware stuff - very nice!

I was planning doing something like warioware too soon - but using liquid fun for the effects.

Ninjadoodle · December 2017

@antix - thanks for the offer! I will definitely let you know, but for now I just want to publish it

I will put in on my site and make adjustments to it over the next couple of weeks.

@SinisterSoft - Thanks! I'd love to see what you have in mind. Sounds like it would be a fun game.

Ninjadoodle · December 2017

Hey guys

Here is a new Geeking with Gideros video

This time I talk about putting an image on the stage and changing it's anchor point.

***

I'm still confused by the order of file execution tho. I understand that everything get's loading, so that main.lua can use the assets / files. What confuses me however is the work executed.

I was under the impression that the file is only executed when I (for example) get main.lua to visit level1.lua etc.

I though the files are loaded into memory in the background.

hgy29 · December 2017

Basically all files are executed, as if they were concatened together (they actually are...), except for those files marked as 'exclude from execution'. The order in which they are executed is determined by the code dependencies you set in gideros studio, with the implicit rule that init.lua is executed first and main.lua executed last.

If you exclude files from execute and use 'require' to load them, then they are executed at the time require is executed.

Ninjadoodle · December 2017

Cool, thank for the explanation - what would be the correct way / word to distinguish between a file executing vs running let's say its own init() function?
