Usage

### Making Screen Effects using the builder Deno file: > **IMPORTANT**: > Using this method requires the following to be installed in your system: [Deno](https://deno.land/), [ffmpeg](https://ffmpeg.org/). After getting those, restart your computer. A screen effect is composed of multiple font frames that the datapack uses to show the animation. A **utility Deno JS file is provided** with the resource pack inside the `screen_effects` folder to make this process easier. #### 1. Making the animation > **NOTE**: > - You can use any image editing software you like as long as it can **export your animation into a spritesheet**. [Aseprite](https://www.aseprite.org/) has this functionality. > - It is recommended to make a **256x256 .png file** for the best results. - Start by creating an animation.

- Export your animation into a **vertical** spritesheet inside the `screen_effects` folder.

- You can add more spritesheets inside the `screen_effects` folder if you want more screen effects. #### 2. Building the animations - To prepare for building the animations, go inside the `buildScreenEffects.js` folder and adjust these configs. ```js // -------------CONFIGS--------------- // Replace with the namespace you use! const NAMESPACE = "trplnr"; // If you want the font JSON files to be formatted, make this boolean true. const prettyPrintFontFiles = false; // If you want to see the ffmpeg logs, make this boolean true. const showFFMPEGLogs = false; // ----------------------------------- ``` - To make your amazing animations usable by the datapack, You can run a command in your terminal to convert your spritesheets into frames! - Open your preferred terminal and **make sure you are inside the `screen_effects` folder**. - After that, run this command ```sh deno run --allow-all .\buildScreenEffects.js ```

- After running that, if everything is successful, it should look like this:

- Congrats! You've successfully turned your wonderful animations into frames! :tada: - If you only want to to compile 1 spritesheet, simply run ```sh deno run --allow-all .\buildScreenEffects.js filename.png ``` --- ### Registering the Screen Effects The datapack needs to have data to know what a screen effect is so you have to register it. Here is an example on how you can register one. > ScreenEffect schema shown below this section. ```mcfunction # To add your own screen effects to the global registry, # simply copy what is shown here. data modify storage example:scrfx_data screen_effects set value { \ "examples:toast": { \ tps: 1, \ frame_count: 31, \ path: "example:scrfx/exampletoast" \ }, \ "examples:transition": { \ tps: 1, \ frame_count: 69, \ path: "example:scrfx/exampletransition", \ callbacks: { \ "26": "say This frame covers the whole screen" \ } \ }, \ } function scrfx:add_screen_effects {storage: "example:scrfx_data", path: "screen_effects"} ``` ### The ScreenEffect Schema This is the definition of a ScreenEffect. ```ts { /** * The name of the screen effect, * preferrably namespaced. */ "ns:identifier": { /** * How fast each frame * shows up measured in ticks. * * Just like fps but well in ticks. * * Must be above zero. */ tps: , /** * How many frames are in the animation. */ frame_count: , /** * The font resource location * of the animation with the * number at the end removed. */ path: , /** * Defines what commands run in a certain frame. * * Optional. */ callback?: { "": "", ... } } } ``` ### Running the Screen Effects - Declare the animation to be played inside the `scrfx:in id` storage. - Then execute as a player and run `scrfx:play`! > Example: ```mcfunction data modify storage scrfx:in id set value "ns:identifier" execute as Trplnr run function scrfx:play ``` - You have successfully played a screen effect! 🎉
