SinisterSoft · January 2019

Here is a new game I made over Christmas...

Available on google play...

I need to add more levels, but it's playable.

Apollo14 · January 2019

I can't open it:

Just uploaded a fix, I forgot to exclude that file from execution! ...

The new version is 1.22

keszegh · January 2019

it feels nice, @SinisterSoft,
some small comments:
-on my 5.5inch screen i feel that the bricks are a bit too small and too many.
-instead of centering, the play area could be on the top so that i can move my fingers below it as on a touchpad. in the current setup i repeatedly accidentally cover the moving brick with my fingers which makes me miss the ball.

SinisterSoft · January 2019

Thanks for the feedback.

I was going for the brick size to be the same as Atari's Breakout game, it's 3 more columns than Arkanoid had. On a 6" or tablet they look just about right, but I'll see what my kids say and if they think they are too small I'll redo them.

I'll make the pad at the bottom an option I think, I'll look into it.

keszegh · January 2019

i think if you can solve the issue of the finger covering the play area, then the size of the bricks could be just fine.

SinisterSoft · January 2019

I think it will be best as an option:

Auto (depends on aspect ratio, border size at bottom)
On (may shrink the play area if no border at bottom)
Off (in case the are using a joypad or keyboard)

keszegh · January 2019

sounds cool

I'd also make all objects bigger in game (ball, pad and everything)
but that's my personal taste, I don't know what majority of users like

SinisterSoft · January 2019

@Apollo14 What size screen are you on?

SinisterSoft · January 2019

I've made the it so there are less bricks across the screen, so it scales bigger for everything. It's version 1.24

I can't make them much bigger than that or there won't be any level variety.

keszegh · January 2019

much better. when level 1 ended it crashed for me, i've sent the error log via google.

SinisterSoft · January 2019

I'll take a look.

SinisterSoft · January 2019

Can't find a crash on either the normal google play console or crashlytics...

dreiko65 · January 2019

Nice little game. I like it a lot. Its smooth and classic. The colors are nice and the animations are smooth and keep you engaged.
@SinisterSoft maybe between stages you could give some time to the player to let them know that a stage change is comming so they can get ready.
Thats all. Looking fwd for the next release.

hmm, something offered me to send a bug report and i ok'd it. maybe it was lost nevertheless.

SinisterSoft · January 2019

@dreiko65 I want the game to be none-stop, but I know what you mean. I may put something at the top of the screen, like a bonus for how many gold bars they got (if any on screen), etc... (the level can end with gold bricks still on there - the ones that clang and you have to hit them twice)

@keszegh Can you try it again, it may have been some kind of glitch?

my screen is 5.5 inches @1080p

SinisterSoft · January 2019

@Apollo14 Is the new size better for you? (I made the brick bigger and less of them)..

Now I think it's perfect!
(personally, if I made pong game, I'd check all top tier pong games, there will be many stuff to learn and adopt from them; I don't know what size is best for most of the audience, but they certainly do)

SinisterSoft · January 2019

@Apollo14 Thanks

It's just a quick game to get closer to hyper casual from my normal type of game.

I'm going to add some information overlay type icon to add to those that drop so say what they mean next and add more levels - then release it from Beta to production.

SinisterSoft · January 2019

Uploading v1.27, there are a couple more levels and now when you collect a falling item then an icon is shown to let you know what you collected.

keszegh · January 2019

it did not crash this time,
yet at level change I've died immediately as the one ball which i tried to catch out of three disappeared while the surviving ball was far and close to the bottom already. that's a bit cruel.

SinisterSoft · January 2019

That's odd, I thought I coded it so the highest ball survives. I'll check it out.

SinisterSoft · January 2019

I think I see what you mean - they were both close to the bottom. I'll rework it so if the are in the bottom half then it's the one closest to the player that survives.

Press release seems to be spreading

I'm not sure why this happened, crashlytics didn't report anything - all that's there are 3 crashes that are now fixed (from a few days ago). Maybe @hgy29 knows what that report means?

hgy29 · January 2019

I can vaguely tell you that the crash was caused by a corrupt event structure which gideros tried to process. Hard to say which part of gideros produced that event though. My guess is that it is a threading issue somehow, gideros was probably trying to process an already released structure or some kind of memory corruption occured

SinisterSoft · January 2019

So he was just unlucky.

MoKaLux · March 2019

hello there gideros people, I am restarting from scratch learning gideros and lua. I did the basic tutorials and now I am at the stage of "making" a brick game and I have a question please.
I build the level in 2 parts like so:
A

level = {}
for l = 1, 6 do
   level[l] = {}
   for c = 1, 15 do
      level[l][c] = 1
   end
end

B

local bx, by = 0, 0
for l = 1, 6 do
   bx = 0
   for c = 1, 15 do
      if level[l][c] == 1 then
         local r = Pixel.new(0x00ff00, 0.75, brickwidth, brickheight)
         r:setAnchorPoint(0.5, 0.5)
         r:setPosition(bx, by)
         stage:addChild(r)
      end
      bx = bx + brickwidth
   end
   by = by + brickheight
end

Then in the game loop (ENTERFRAME) I check the collision like so:

-- BRICK COLLISION
local c = math.floor(myball:getX() / brickwidth) + 1
local l = math.floor(myball:getY() / brickheight) + 1
if c >= 1 and c <= 15 and l >= 1 and l <= #level then
   if level[l][c] == 1 then
      ballspeedy = - ballspeedy
      level[l][c] = 0
      deleteBrick(l, c)
   end
end</pre>

My question is how do I remove the brick from the stage?
I would like to remove the brick which is at level[l][c] directly. Is it possible to do something like table.removeChildAt(level[l][c])?

I don't want to use external code yet, I want to use only gideros classes for now.

Thank you for your help.
