Three ABAP Games

horst_keller · ‎01-18-2016

Look what I've found.

Under the cloak of "Examples of Expression-Oriented Programming" recent versions of the Example Library of the ABAP Keyword Documentation contain three ABAP games.

Jaw Breaker

Not too demanding but colorful ...

Mine Sweeper

Time-honored and well known ...

2048 Game

A recent smart phone game and a real challenge ...

Wanna play?

If you have a recent ABAP system (7.40, SP09 and higher), you find the programs directly in the system.

(The examples from the 7.50 documentation can rely on 7.50 features. For 7.40, there are 7.40 examples).

If you have an older 7.40 ABAP system, you can copy the source code from the documentation or from the attached text file.

If you have a release older than 7.40, you can copy old fashioned 7.00 source code from the attached text file . Maybe you also have to replace the usage of CL_DEMO_INPUT with PARAMETERS then.

Only outside working hours, of course.

Wanna Contribute?

Maybe, the pattern used in these games (usage of CL_ABAP_BROWSER etc.) motivate you to create some other games?

Note

Due to the discussion below (thanks enno.wulff!) I adjusted the HTML output of

DEMO_JAWBREAKER_HTML_740
DEMO_JAWBREAKER_HTML_700
DEMO_MINESWEEPER_740
DEMO_MINESWEEPER_700

in Release 7.50, SP03. You find the new sources in the attached text file .

Hopefully, those run for all combinations of SAP GUI and IE. If not, next round ...

Horst,

guess you compiled those games outside your working hours, too, right? Or was it just for demonstration purposes to explain new features of the ABAP language. :wink:

Once my boss explained to me, that I'm working in the moment I'm doing something that is related to ABAP or SAP ...

MichiFr · ‎01-18-2016

That's a good reason and explanation :cool:

nikolayevstigneev · ‎01-18-2016

Time to brush up JavaScript? :smile:

horst_keller · ‎01-18-2016

Copy&Paste ... :wink:

nikolayevstigneev · ‎01-18-2016

Woo-hoo, next time I need to do a copy-paste I'll explain that Horst advised me to do that :lol:

horst_keller · ‎01-18-2016

Only for HTML/JS of course, in ABAP we're good enough :twisted:

ennowulff · ‎01-18-2016

Hello Horst,

"Click" is not working... :sad:

at_click FOR EVENT sapevent OF cl_abap_browser IMPORTING action

I did test it on two systems now.

At least a fine, compact and much to small demo (on high resolution displays) :wink:

Greetings Enno

Waiting for the day the canteen will offer ABAP noodles with SELECTed dressing... :wink:

A company can save money everytime a program becomes faster or better or deeper in giving details or functionalities .

Games are among first sources of alghorytm of efficiency example applications and often they're the best way to achieve a complex result.

So we should study Games and alghorytm and save money and time for the company or instead we should change job = GAME OVER :smile:

horst_keller · ‎01-18-2016

"Click" is not working...

Makes me wonder. Never had problems with that.

Can you check SAPEVENT in program DEMO_HTML_BROWSER?

CL_ABAP_BROWSER should work since 702.

Horst

ennowulff · ‎01-18-2016

The Demo_HTML_Browser works. In Jawbreaker I have no pointing hand on "Mouse Over". There is no link...

Unless I adjust the demo and put something in the table cell:

CONCATENATE line

'<td class="c' cc '">'

'<a href="sapevent:x' xn 'y' yn '"/>X</td>' INTO line.

...

horst_keller · ‎01-19-2016

Now that's amazing ...

The Jawbreaker game seemed to work fine in the HTML control of SAP GUI since I implemented it, and now that.

In order to check, I extracted an HTML file to the disk:

<html>

<head>

<meta http-equiv="content-type" content="text/html; charset=utf-8">

<style type="text/css">

a{text-decoration:none;width:18px;height:18px}

.c1{background-color:lightblue}

.c2{background-color:cornflowerblue}

.c3{background-color:darkblue}

.c4{background-color:steelblue}

</style>

</head>

<body leftmargin="35" topmargin="60" scroll="no">

<table border="0">

<tr>

<td class="c1"><a href="sapevent:x01y01"/></td>

<td class="c1"><a href="sapevent:x02y01"/></td>

</tr>

<tr>

<td class="c1"><a href="sapevent:x01y02"/></td>

<td class="c2"><a href="sapevent:x02y02"/></td>

</tr>

</table>

</body>

</html>

And yes, it looks bad in all browsers ...

Oh my!

Don't ask me, why it works fine in most (?) SAP GUI controls but not in yours.

Found a correction that works for me:

<html>

<head>

<meta http-equiv="content-type" content="text/html; charset=utf-8">

<style type="text/css">

.bx{text-decoration:none;width:18px;height:18px;cursor:hand}

.c1{background-color:lightblue}

.c2{background-color:cornflowerblue}

.c3{background-color:darkblue}

.c4{background-color:steelblue}

</style>

</head>

<body leftmargin="35" topmargin="60" scroll="no">

<table border="0">

<tr>

<td class="c1"><a href="sapevent:x01y01"/><div class="bx"></div></td>

<td class="c1"><a href="sapevent:x02y01"/><div class="bx"></div></td>

</tr>

<tr>

<td class="c1"><a href="sapevent:x01y02"/><div class="bx"></div></td>

<td class="c2"><a href="sapevent:x02y02"/><div class="bx"></div></td>

</tr>

</table>

</body>

</html>

Does it work for you? If this is the case, I think about adjusting DEMO_JAWBREAKER_HTML_... (and Mine Sweeper) in 751.

Thanks for notifying!

Horst

ennowulff · ‎01-19-2016

Yes, it does! Thanks. The report needs some more changes than just adding bx and div. LINE (C255) is too small to take the changes...

I always cause trouble with my computers configuration. :smile:

horst_keller · ‎01-19-2016

It depends on the GUI version. I had to add a ";cursor:hand" to the bx class above otherwise it would not work in recent GUIs any more!

What SAP GUI version are you using?

Former Member · ‎01-19-2016

Thanks for the correction. Got the same Problem with jawbreaker and minesweeper, too.

With the correction it works fine 😉

ennowulff · ‎01-19-2016

740 Final Release

Dateiversion 7400.1.4.1106

Build 1598106

horst_keller · ‎01-19-2016

Same as I :neutral:

ennowulff · ‎01-19-2016

Isn't it relevant which IE version is taken by the GUI?

Maybe these are different?

I do not know how to identify the internal version...

horst_keller · ‎01-19-2016

It's both, SAP GUI and IE, because SAP GUI influences the browser's standard CSS.

In order to work out right in my SAP GUI as well as other browsers, I finally will combine an a-style and an bx-style.

... `.bx{text-decoration:none;cursor:hand;width:18px;height:18px}` &&

`a{width:18px;height:18px}` ...

Oh boy ...

(In fact I'm fighting with that crap everyday for providing the ADT version of the ABAP Docu ...)

former_member185171 · ‎01-21-2016

Nice,

I copied the code but get an error during activation:

I didn't change anything in the declarations ...

Regards.

Kris

horst_keller · ‎01-21-2016

Hey, some 7.50 features crept in ...

Object Component Selector After Table Expressions

In the 7.40 documentation, there's a 740 runnable code.

:razz:

former_member185171 · ‎01-21-2016

OK.

Problem solved!

Kris

matt · ‎01-23-2016

This reminds me. 17 years ago just before Christmas 1999 things were a little slow at work, so, on a 31H system, I wrote a game in ABAP using this report's autorefresh technique.

There was a ship going across the top of the screen from which you could drop depth charges on the submarine moving randomly at the bottom of the screen.

It was a rehash of a game I first wrote in 1982 for a ZX81. Autorefresh there was bit easier!

horst_keller · ‎01-23-2016

Missing (and not in action): Classical Dynpro as APC-client.

Former Member · ‎01-24-2016

"Missing (and not in action)"?

horst_keller · ‎01-24-2016

Not available up to now, APC for refreshing dynpro screens. You need user interaction on a dynpro screen in order to pass contol to ABAP.

Former Member · ‎01-24-2016

Oh, that minor issue.

Who uses classic SAP GUI anyway? :wink:

leonardo_buryanteixeira · ‎01-29-2016

Once a User requested a report ALV, the result should be updated without user action.

Immediately I used the functionality of my ZTETRIS.

Former Member · ‎02-06-2016

did you thought about putting it on GitHub?

horst_keller · ‎02-08-2016

SCN should be sufficient ...

Former Member · ‎02-10-2016

Nice stuff :smile:

Thanks for sharing it.

Peter_Inotai · ‎02-10-2016

Hi,

It seems program DEMO_GAME_2048_700 has some dependencies on version of cl_demo_input=>add_field( ). In 7.40 SP7 parameter as_checkbox is missing.

After commenting it out, it works fine however :smile:

Best regards,

Peter

horst_keller · ‎02-10-2016

Yes, its all about demos and games, delivered, but not under the constraints for productive coding ...

former_member625950 · ‎08-22-2019

I cannot access the code for systems below 7.4. Would you be so kind and update the link, or upload the code somewhere else?

former_member747638 · ‎05-22-2021

Among Us is a game that is being played by a lot of people today. The game is easy to play with beautiful and funny graphics that attract a lot of users. I think you will like it.

horst_keller · ‎11-29-2022

REDUCE was introduced with 7.40, SP08

Peter_Inotai · ‎11-29-2022

Thanks for the info.

Sorry, meanwhile I deleted my comment regarding REDUCE, because I realized that I have to implement the *_700 versions, not the *_740 in our system. I was blind :sad:
