Author Topic: Cloned Shades (Read 5280 times)

A good while back I wrote this game which is a clone of a game called Shades by a mobile company called UOVO.

I had released it on [abandoned, outdated and now likely malicious qb64 dot net website - don’t go there] and it remained dormant since then. Today I finally got to add it to my GitHub repositories and I decided to post it here too.

Shades is a new take on Tetris, in which you have a falling block that must be placed in the best spot you can find. Once you align four blocks of the same shade you clear a line and get extra points.

The catch is that when you place a block on top of another of the same shade, they'll merge into a darker shade block. Well, you'll see it when you play it.

I'm placing the source code in the box below just for reference, but you will definitely need the resources in the zip file.

Grab the full version from the GitHub release page: https://github.com/FellippeHeitor/Cloned-Shades/releases/tag/v1.0 (binary for Windows included).

'Cloned Shades - by @FellippeHeitor - fellippeheitor@gmail.com
'
'(a clone of 'Shades' which was originally developed by
'UOVO - http://www.uovo.dk/ - for iOS)
'
'The goal of this game is to use the arrow keys to choose where
'to lay the next block falling down. If you align 4 blocks of
'the same color shade horizontally, you erase a line. If you
'pile two identical blocks, they will merge to become darker,
'unless they are already the darkest shade available (of 5).
'
'It has a tetris feeling to it, but it's not tetris at all.
'
'The idea is not original, since it's a clone, but I coded it
'from the ground up.
'
'Changes:
'- Beta 1
'       - So far I got the game to work, but I'm running into issues
'         trying to show scores on the screen, mainly because I relied
'         on POINT to check whether I could move blocks down or not.
'       - There's no interface except for the actual gameboard.
'
'- Beta 2
'       - Been discarded. At some point everything was working well but
'         I managed to screw it all up, to the point I made the decision
'         to go back to beta 1 and start over. I like to mention it here
'         because even failure can teach you a lesson, and this one is
'         not one to forget.
'
'- Beta 3
'       - Converted all audio files to .OGG for smaller files and faster
'         loading.
'       - Game window now has an appropriate icon, generated at runtime.
'       - Block movement has been coded again, and now it doesn't rely
'         on POINT to detect blocks touching each other, but it actually
'         evaluates the current Y position. Like it should have been from
'         the start, to be honest.
'       - Redone the merge animation. Still looks the same, but it had to
'         be redone after the new movement routines have been implemented.
'       - Added a background image to the game board ("bg.png"), but uses
'         a gray background in case it cannot be loaded for some reason.
'       - Code is a bit easier to read, after I moved most of the main
'         loop code into separate subroutines.
'       - SCORES ON THE SCREEN!
'
' - Beta 4
'       - Adaptative resolution when the desktop isn't at least 900px tall.
'       - New shades, which are alternated every time a new game is started.
'       - Visual intro, mimicking the original game's.
'       - Improved game performance by selectively limiting the layering of
'         images in SUB UpdateScreen.
'       - Added a "danger mode" visual indication, by turning on a TIMER that
'         overlays a shade of red over the game play, similar to a security
'         alarm.
'       - Added a menu to start the game or change setting or leave.
'       - Settings are now saved to "shades.dat", and include switches for
'         sound and music, as well as a highscore.
'       - Added an end screen, that shows the score, number of merges and
'         number of lines destroyed during game.
'
' - Beta 5
'       - Fixed game starting with the blocks that were put during the menu
'         demonstration.
'       - Fixed the 'danger' warning coming back from the previous game.
'       - Added an option to select shades (GREEN, ORANGE, BLUE, PINK) or
'         to have it AUTOmatically rotate everytime you start the game.
'         (thanks to Clippy for suggesting it)
'       - Added a confirmation message before clearing highscore.
'       - Added a confirmation message before closing the game with ESC.
'       - Fixed a bug with page _DEST that caused scores to be put in
'         OverlayGraphics page instead of InfoScreen while InDanger
'         triggered the ShowAlert sub.
'
' - Beta 6
'       - ESC during the game shows a menu asking user to confirm QUIT or
'         RESUME. The previous behaviour (in beta 5) was to quit to main
'         menu after ESC was hit twice. Now ESC is interpreted as 'oops,
'         I didn't mean to hit ESC'.
'       - A new sound for when a line is destroyed ("line.ogg"); "wind.ogg"
'         is no longer used/needed.
'       - Added a sound to the game over screen ("gameover.ogg").
'       - Fixed menu alignment issues when showing disabled choices.
'       - Changed code to selectively NOT do what can't be done in MAC OS X
'         (so that now we can compile in MAC OS X, tested in El Capitan).
'       - Three lines of code changed to make the code backward compatible
'         with QB64 v0.954 (SDL): BackgroundColor goes back to being a shared
'         LONG instead of a CONST (since SDL won't allow _RGB32 in a CONST)
'         and inside SUB CheckMerge we no longer clear the background using
'         a patch from BgImage using _PUTIMAGE with STEP. Turns out the bug
'         was in QB64, not in my code.
'
' - Beta 7
'       - Fixed a bug that prevented the end screen to be shown because of
'         the InDanger timer still being on.
'       - Added three levels of difficulty, which affect gravity.
'       - Since speed is different, a new soundtrack was added for faster
'         modes ("Crowd_Hammer.ogg" and "Upbeat_Forever.ogg")
'       - Added FILL mode (thanks to Pete for the suggestion), in which instead
'         of an infinite game your goal is to fill the screen with blocks,
'         avoiding merges at all costs, since they make you lose points (which
'         is indicated by a "shock.ogg" sound and visual warning.
'       - Added a new parameter to FUNCTION Menu, Info(), that holds descriptions
'         for menu items. The goal is to be able to show highscores even
'         before starting a game.
'       - Clicking and dragging emulates keystrokes, allowing basic mouse
'         controls (code courtesy of Steve McNeill - Thanks again!)
'
' - Version 1.0
'       - Fixed: Disabling music through settings didn't stop the music. Duh.
'       - Fixed: Shock sound during Fill mode sounded weird because it was being
'         played inside the animation loop, and not once, before animation.
'       - Fixed: BgMusic selection while in Fill mode.
'       - Added: If player takes more than 3 seconds to choose a game mode,
'         a brief description is shown on the screen.
'       - Added: Quick end screen animation.
'       - Countdown to game start with "GET READY" on the screen.

Hi Fellippe
I find it very interesting and cool,
I need to use massively the eyes for colors.

Thanks to share.

While I was playing with Cloned Shades I got this bug! An invisible block.
Here a screenshot attached

Shades Fellippe Bug of invisible block.jpg

Interesting bug, TempodiBasic! I wonder if I'll be able to ever reproduce it!

Thanks for your interest.

bplus · « **Reply #3 on:** April 15, 2019, 04:14:41 pm »

Well my first, second tries I had no idea what strategy to use, then I got it and played 1.25 hours and still on row 1!

There are some nice graphic and sound effects. The score keeping is a bit funky, it keeps clearing back to 0?

FellippeHeitor · « **Reply #4 on:** April 15, 2019, 04:23:17 pm »

Wow, that's a long run!

Now about the score keeping getting reset... I didn't see it happen yet. Was it at any possible overflow mark?

bplus · « **Reply #5 on:** April 15, 2019, 04:34:22 pm »

Overflow mark?

The stacks never went much past half screen up... using Normal Fill mode.

It would show a score like 5 after a line clears and then a brick or 2 later back to 0. I had to go run errands so did not get chance to read the last screen when game ends.

bplus · « **Reply #6 on:** April 15, 2019, 07:19:40 pm »

Update:

OK, I got to read the directions to the Fill Mode. Blah! I was playing it backwards! Sorry.

Scoring is fine.

FellippeHeitor · « **Reply #10 on:** April 15, 2019, 11:23:36 pm »

Did you try using the mouse to control it as well, bplus?

TempodiBasic · « **Reply #11 on:** April 16, 2019, 03:35:59 am »

Hi Fellippe

I find this game simple and amazing.

here more my feedbacks, they're not criticism but point of view.
1.
Mouse works for drag and drop during the game, not in menu level.
in main screen ,where is the menu, if I stay along on a voice menu it appears the tooltip help&comments, but it doesn't disappear both after a short time both after a long time, both after mouse input (movemouse, click by left button or right button or wheel or all together) and the user must use input keyboard to come back to menu screen (that is back to tooltip Help&comments)

2.
for my poor eyes something the difference between two grades of the same color are not so clear. But this is for me that I'm 51 years old.

3.
I have got another time the bug glitch! But this one I am not able to get screenshot because the game goes to fast and merge the block invisible with another of the same grade_color.
4. (Do you think to implement a mouse or Key command for Pause during the game?)
....
3. (continue) however I can confirm that to get the bug_glitch you must move by keyboard to right (press right key) just before the block is to touch the stack..... (in Tetris you can match also in this manner the blocks...)

5. this can be a feature or a bug, it depends by the rules of the game that are not avaible in the program
6. do you think to implement a Help for dummies like me? ie use of arrows and mouse , grading of colors (how many grade
of colors are in the level? I think this is important because you can know how blocks can merge in vertical and this one
depends by the feature_bug of point 5)
5. (continue) what happens in the game is that:
if I have a line in which putting the matching block it is completed and must be deleted BUT the block under this last block has the same color, well the program merge the two block in vertical and it doesn't clear the line. Also this can be a feature or a bug, it depends by rules of the game that I have no

example: B
|
v BBBB
B NNNN

Thanks to read
Sorry for many words

FellippeHeitor · « **Reply #12 on:** April 16, 2019, 06:45:13 am »

Hi, TempodiBasic,

I can't take credit for the idea, since it's a clone as stated, but I'm glad you enjoy playing my version.

1- Mouse for the main menu would actually make a lot of sense. Thanks for the suggestion.
2- The idea is that the shades are close enough in order to get you confused. The gradient background is there to help you get even more confused.
3- I'll try to reproduce the invisible block bug with your instructions.
4- ESC for pausing.
5- Not having too many of the rules explicit is part of the original game's "magic", so it is by design.
6- Because of the tetris-like nature, I feel explaining that the arrow keys are to be used is a bit overkill.
5- (continuation) Again, it is a bit frustrating in that sense by design :-)

Thanks for playing!

I didn't know, so I just tried the mouse and did not like for block control. For once the arrow keys seem more natural control.

So that background and shades were meant to confuse! Yeah at top it seems a shade different than when reach bottom.

So esc key is pause, good to know. Like TempodiBasic I was expecting mouse to work on menu pages, mouse over pop-up description of Fill Mode would have saved me some confusion about the mode.

This game is addictive! I like more than Tetris.

I agree! Back when I wrote it I was so addicted to playing it on my phone that I decided to give it a try in QB64 so that my mind could do something productive out of it! The guys at UOVO did a very good job creating the concept :-)
