Title: [2D Platformer] Melting Saga
Post by: Sygmei on March 21, 2016, 10:58:42 pm

Hey guys !
So about the game :
It's a 2D Platformer with a lot of RPG aspects (spells, levelling, etc...), epic battles and so more.
Right now there isn't much gameplay content but the platformer engine is almost done :)
All the engine is written in C++ in top of SFML.
The game logic is written in Lua with a binding named Kaguya (by Satoren).

Here's an old trailer :

And an other video to show more recent features :)

Nice. Looking good!!!

The jumping looks a bit teleporty. Don't know if that's intended. But i like the pace of the game and the looks are nice :D

Keep posting the updates please

It looks really well done. The newer video is impressive.

The jumping looks a bit teleporty.

In the older video, certainly; I agree. It seems to be the sudden extreme velocity when jumping away from grabbing a wall...

Thanks a lot for the answers :)
And yeah, sometimes it's a bit glitchy :/
If some people are interested to help the developpement by testing the game and try to find some bugs, it would be cool :D

I'm always in for some testing!

Sign me up as tester. I love platformers. :P

A little screenshot of the future updater :D
This updater will be released in a few days / weeks to test the debug versions of Melting Saga.

Any suggestions about design ?
Or some feature you would like to see in the updater ?

Make sure it's idempotent (https://en.m.wikipedia.org/wiki/Idempotence) so that failed updates are rolled back perfectly and can be re-tried.

Post by: Sygmei on March 28, 2016, 08:02:09 pm

Good idea, I don't know how to implement it yet, but I'll try :)

Title: Re: [2D Platformer] Melting Saga
Post by: Jesper Juhl on March 28, 2016, 08:19:21 pm

Here are a few ideas:

1. Create a filesystem snapshot before the upgrade that you can roll back to if the upgrade fails.

2. (Something I did for a product at a previous employer) - install every update in a new directory, then upon (re)launch of the app, find the newest update dir and calculate a checksum for all files in it and compare to a csum file in the dir - if no match, delete the dir and try the next - continue until success. Then launch app from newest successful dir (which may then retry downloading and applying updates). Requires a small "find best dir and launch app wrapper" that you really don't want to screw up during an update, but other than that seemed to work well.

3. Copy all files before changing them and then move them back if anything fails.

4. Make your app dir a git repo.

Looking good! Is the shapeable platforms a mechanic of the game or just an editor thing?

Title: Re: [2D Platformer] Melting Saga
Post by: Sygmei on March 28, 2016, 10:28:14 pm

You mean, being able to move platforms while playing ?
It probably wont be in the game, but the engine can do it.
So if someone want to create a game with that feature, feel free to use my code :D

it looks so awesome, i have looked to your youtube change, i like the video-dev for this game.

i'm now working on 2d platformer (Mario) and i'm using tiled editor which has polygon shape feature for object layer but yours is much flexible  from what i have seen in this video. and yeah, i'm interesting to try it but where the code at. could you post a link to the code.

Title: Re: [2D Platformer] Melting Saga
Post by: Sygmei on March 29, 2016, 01:01:18 am

I just posted the sources on Gitlab (similar to Github) today, I'll correct some little bugs, implement a few things and then I'll release the code and start a public alpha :)
The first release will not contain a lot of gameplay, but you'll still be able to create your own maps and scripted objets :D

Title: Re: [2D Platformer] Melting Saga

Well, sources are available !
CMakeLists.txt isn't working at the moment :( (I'm working on it)
All needed dependancies are in the README

Hi! I was wondering how did you implement the updater. The game looks neat btw.  :P

Title: Re: [2D Platformer] Melting Saga
Post by: Sygmei on April 05, 2016, 03:07:54 am

Updater is a borderless window with custom GUI :)
It uses a system to check if client file fingerprint is equal to server file fingerprint.

If you want to test the game, you can now use the Updater :D
http://188.226.212.159/updater/Updater.zip

To launch the game, first of all, start Updater.exe and click on Update button.
Wait for the Updater to check all the files and it should start to download everything.
When it's done, go to MeltingSaga folder and launch MeltingSaga.exe

Cool! :)

The updater downloads everything into a subdirectory MeltingSaga, is this supposed to work like that?
Would be cool if the updater after downloading showed a button to start the game directly.

Could you add an option for limiting the FPS? My GPU goes crazy when it has to render at 1700 FPS. ;D

Title: Re: [2D Platformer] Melting Saga
Post by: Sygmei on April 29, 2016, 10:47:17 am

Yes :D It's supposed to download everything in the MeltingSaga folder :)
A "Play"  button is planned, I just have to figure out how to execute the game from another exe
And yus I'll add an option to limit the FPS :3 (And you have a good PC, I can't even get 1700 FPS :( )

I suspect it'll need platform-specific code, but I've used this successfully in the past :

Hopefully it helps! Also the game is looking good!

Hi ! Your project is nice.

However I tried to change the CMakeLists.txt and some other files in order to try MeltingSaga on my PC (I'm using Manjaro Linux). I'm able to compile, but I've strange errors when I try to run MeltingSaga :

[klafyvel@klafyvel MeltingSaga]$ ./MeltingSaga
Data/GameScripts/ScrInit.lua:20: unexpected symbol near ';'
[string "protect("ID")"]:1: attempt to call global 'protect' (a nil value)
[string "protect("Private")"]:1: attempt to call global 'protect' (a nil value)
[string "protect("Public")"]:1: attempt to call global 'protect' (a nil value)
type mismatch
[string "table.insert(Core.ImportedLibs, "Console")"]:1: attempt to index global 'Core' (a nil value)
PANIC: unprotected error in call to Lua API (attempt to index a nil value)
 

Any idea ?  :D

Title: Re: [2D Platformer] Melting Saga
Post by: Sygmei on April 30, 2016, 06:44:32 pm

Mmh..
First of all, delete the Data / Sprites folder if you have any in the same folder of the executable.
After that, download this : http://188.226.212.159/updater/Data.zip
And this : http://188.226.212.159/updater/Sprites.zip
Unzip the two archives at the same location as the executable.

You also need to ensure that you used Lua 5.3 when compiling the game.
Could you show me the content of your CMakeLists.txt :) ?

Title: Re: [2D Platformer] Melting Saga
Post by: klafyvel on April 30, 2016, 07:03:25 pm

Ok, so I just downloaded the two archives and unzipped both them in the same directory as the MeltingSaga exectuable, but I still get the same error  :( .

[klafyvel@klafyvel bin]$ ./MeltingSaga

Of course :

(click to show/hide)

cmake_minimum_required(VERSION 2.8 FATAL_ERROR)

project(MeltingSaga)

if(LM_STATIC_SFML)
  SET(SFML_STATIC_LIBRARIES TRUE)
endif()
include_directories(include)
file(

        GLOB_RECURSE

        source_files

        Source/*


)
add_executable(

        MeltingSaga

                ${source_files}

)
set(CMAKE_MODULE_PATH "${CMAKE_SOURCE_DIR}/cmake_modules" ${CMAKE_MODULE_PATH})
if(WIN32)
  find_package(SFML 2 REQUIRED graphics window audio system network main)
else()
  find_package(SFML 2 REQUIRED graphics window audio system network)
endif()
target_link_libraries(MeltingSaga ${SFML_LIBRARIES})

find_package(OpenGL REQUIRED)
target_link_libraries(MeltingSaga ${OPENGL_LIBRARIES})

include(cmake/FindLua.cmake)
include_directories(${LUA_INCLUDE_DIRS})
link_directories(${LUA_LIBRARY_DIRS})
include_directories("include")

target_link_libraries(MeltingSaga ${LUA_LIBRARIES})

target_compile_features(MeltingSaga PRIVATE cxx_range_for)
 

It is not really beautyfull but it works :P .

I also replaced every

#include <Windows.h>

to

#ifdef _WIN32
#include <Windows.h>
#endif
