How do you add trophies ingame?

Go to the GJ-Game-API forum and there you can find several threads about this matter.
Which game editor are you using? GameMaker? GameMaker Studio? RPG Maker? Unity? Unreal?
If we know which engine/programming language you use, we can help you to get this show on the road.

I use unity explain plz

Then you should go to this thread, where you can find the API library for Unity. If you have any questions about its implementation and usage, you should ask the author of that specific thread.

I'm late finding this thread, but I use GameMaker: Studio. How would I add trophies?

I never used GameMaker:Studio myself, so I don't know how to code in that, however you can take a look here. I must note that is hasn't been updated in 5 years, so I hope it still works.

This may sound dumb but I'm using scratch what then?

As far as I know scratch does not support the required features to make usage of the GJ API possible.

Oh. Thanks for telling me though.

i also use game maker studio

The engines themselves do not support trophies, however for many languages and alternate developing tools, libraries are created which can help you here... So that should not be the problem.

When it comes to game engines, there are many out there, and whether you wanna dive into the low-level languages such as C/C++/Pascal or a bit higher level C#/Java very highlevel such as Lua or even languages that don't require code at all, such as ClickTeam Fusion or Stencyl, you do need to understand a bit of computer logic, and you will need a bit of a basis of mathematical insight.

These words spoken by Dennis Ritchie (the inventor of the C programming language) are to be taken to heart, whatever choice you make.

Now ClickTeam fusion is very popular here, as it doesn't require code. Now I never used it myself, I have seen screenshots of it which reminds me a lot of actual code though. Now Godot for example does require to write code, but as far as I can see it looks very simple and best of all, it's free. There's also Unity, which requires the use of C#, which is a more complicated language, but still easy to learn. Unity has a free and a paid version, however the free version is good enough for inexperienced people, but note that your players will see the message "Made with Unity" before the game starts.

I would not recommend you to dive into C or C++ before you've tried other languages first and find out you're pretty good in it.

Now before you start on your horror game, it can be a wise thing to try make a few crappy games first in order to get a bit of the logic, which is basically the reason why I referred to Ritchie's quote. This way you can learn the basics well. Check if there are good tutorials about the language and start experimenting first. When you think you found your preferred tool, and made your crappy programs and think you found what is best to use, then you can start out on your horror project.

I'm sure you don't really like my answer, but this is the unclouded truth. People just yelling the name of a language/engine are overall just focused on their own views. I have however a long list of languages I used, and I can say they all have their pros and their cons.

Never used UE4 myself, but as far as I know the engine is set up with professional game developers in mind. ClickTeam Fusion can be a good way to start, and it has by far more possibilities than Scratch. The famous game Five Nights at Freddy's was developed with ClickTeam Fusion, showing that you can make something that is quite marketable with it.

Good luck ;-)

I'm making a game in Scratch, and then turning the code to JavaScript. Would this work? ( Sorry for necroposting, I was just curious )

If you know how to code JavaScript and thus how to modify the JavaScript code in order to make it do the calls to Game Jolt, then yes. You should however realize that JavaScript code generated by converters (heck code to any language generated by converters) tend to look very ugly and can even to experienced coders be a bit hellish to dig through.

okie doke.

You won't like my answer. Not at all.
Scratch has no support for http or https calls, which is required to make this possible.

@Tricky i use RPG Maker MV and i heard it uses Java code, how could i add trophies?

I don't know since I never used RPG Maker or any variant of it.
Perhaps you can check this list, to see if somebody made a library for it.
Since you say it uses Java code (actual Java and not JavaScript? I ask as the two are completely non related to each other, but often mixed up), so perhaps trying out if you can get the Java library to work could be a good start.

i am late ik, but i use construct 2

I'm sorry. All I know about Construct is that it exists.
I don't know if people made an API for it. If Construct can make calls over the http or https protocols it should be possible though.

You nerd to install a plugin called Construct 2 API (i think) and ALAKAZAM! You can add trophies to the game!

I use scratch and make the scratch game to .exe explan please

I use scratch

late reply but turbowarp supports it
