TaCZ的无限子弹

本章涉及内容：按键注册和使用、forgeevent、loadclass、paint、玩家数据 涉及模组及版本:

2. tacz-1.20.1-1.0.3-all

3. architectury-9.2.14-forge

主要部分

const $GunShootEvent = Java.loadClass("com.tacz.guns.api.event.common.GunShootEvent")
const $Integer = Java.loadClass("java.lang.Integer")
const $ModSyncedEntityData = Java.loadClass("com.tacz.guns.entity.sync.ModSyncedEntityData")
const $AbstractGunItem = Java.loadClass("com.tacz.guns.api.item.gun.AbstractGunItem")

ForgeEvents.onEvent($GunShootEvent,event=>{global.gse(event)})
global.gse = event =>{
    try{
        // 处理事件，如果为客户端则不处理
        if(event.logicalSide.isClient()) return;
        let item = event.getGunItemStack();
        // 获取玩家数据，判断玩家是否处于无限子弹模式
        if(event.getShooter().data.get("frenzyOpen"))
            item.nbt.merge({GunCurrentAmmoCount:$Integer.decode​(
                item.nbt.getInt("GunCurrentAmmoCount")+1+""
            )});
    }catch(err){
        console.warn(err);
    }
}

该代码获取枪械物品的nbt，然后将子弹改为不消耗

注册按键

const $KeyMappingRegistry = Java.loadClass("dev.architectury.registry.client.keymappings.KeyMappingRegistry");
const $KeyMapping = Java.loadClass("net.minecraft.client.KeyMapping");
const $GLFWkey = Java.loadClass("org.lwjgl.glfw.GLFW");

ClientEvents.init(event=>{
    global.regKeyFrenzy = new $KeyMapping(
        "key.meng.frenzy",
        $GLFWkey.GLFW_KEY_GRAVE_ACCENT,
        "key.keybinding.meng.special_abilities"
    );
    $KeyMappingRegistry.register(global.regKeyFrenzy)
})

关于注册按键

注册按键的汉化和处理 client_scripts

ClientEvents.lang("zh_cn",e=>{
    e.add("key.meng.frenzy","狂暴模式")
    e.add("key.keybinding.meng.special_abilities","枪械技能")
})

ClientEvents.tick(event => {
    const key = global.regKeyFrenzy;
    if (key.isDown()) {
        if (!event.player.getPersistentData().getBoolean("frenzy")) {
            event.player.sendData("frenzy")
            event.player.getPersistentData().putBoolean("frenzy", true);
        }
    } else {
        if (event.player.getPersistentData().getBoolean("frenzy")) {
            event.player.getPersistentData().putBoolean("frenzy", false);
        }
    }
})

        }
    }else{
        n /= cdMultiples;
    }
    event.player.data.put("frenzyCount",n);
    event.player.data.add("frenzyOpen",!open)
})

// 在退出时获取到玩家的cd时间记录到持久化数据
PlayerEvents.loggedOut(event=>{
    event.player.persistentData.putInt("frenzyCount",event.player.data.get("frenzyCount"));
})

//在进入游戏时读取玩家持久化数据的cd时间
PlayerEvents.loggedIn(event=>{
    event.player.data.add("frenzyCount",event.player.persistentData.getInt("frenzyCount"));
})

一些注意事项

1. 该项目只是作为示例，很多地方并不是最优解，可自行进行解决

2. 如果对该项目代码部分不满可以将修改好的代码上传至gitee项目仓库

3. 注册按键不要打包给服务器(具体看关于按键注册的注释)
