教程：夺旗战

🔴 Advanced⏱️ 40 min

构建两队对抗的夺旗游戏。

你将学到

• 队伍系统设置
• 旗帜拾取和夺取逻辑
• 距离检测触发器
• 多队伍计分

最终效果

两队竞争偷取敌方旗帜并带回己方基地。

第一步：设置

import teams::*
import effects::*

const RED_BASE_X: int = -50;
const RED_BASE_Z: int = 0;
const BLUE_BASE_X: int = 50;
const BLUE_BASE_Z: int = 0;
const BASE_Y: int = 64;
const WIN_SCORE: int = 3;

第二步：游戏状态

struct GameState {
    running: int,
    red_score: int,
    blue_score: int,
    red_flag_taken: int,
    blue_flag_taken: int
}

let game: GameState = {
    running: 0,
    red_score: 0,
    blue_score: 0,
    red_flag_taken: 0,
    blue_flag_taken: 0
};

第三步：初始化

@load
fn init() {
    scoreboard_add_objective("ctf_team", "dummy");
    setup_two_teams();
}

第四步：队伍分配

fn assign_teams() {
    let count: int = 0;
    foreach (p in @a) {
        if (count % 2 == 0) {
            team_join("red", p);
            scoreboard_set(p, "ctf_team", 1);
        } else {
            team_join("blue", p);
            scoreboard_set(p, "ctf_team", 2);
        }
        count = count + 1;
    }
}

第五步：旗帜拾取

fn check_flag_pickup() {
    foreach (p in @a[team=blue]) {
        execute if entity p[x=-52..-48, y=62..68, z=-2..2] run {
            if (game.red_flag_taken == 0) {
                game.red_flag_taken = 1;
                tag_add(p, "has_flag");
                announce("§9蓝队 §f拿到了 §c红旗§f！");
                glow(p, 9999);
            }
        }
    }
}

第六步：夺旗得分

fn check_flag_capture() {
    foreach (p in @a[team=blue, tag=has_flag]) {
        execute if entity p[x=45..55, y=62..68, z=-5..5] run {
            game.blue_score = game.blue_score + 1;
            announce("§9蓝队 §a得分！");
            tag_remove(p, "has_flag");
            place_flags();
        }
    }
}

第七步：死亡时归还旗帜

玩家死亡事件由当前的 @on(PlayerDeath) 触发。事件处理器以死亡玩家为 @s 执行，适合用来检查和清理旗手状态。

@on(PlayerDeath)
fn on_player_death() {
    execute if entity @s[tag=has_flag] run {
        let team: int = scoreboard_get(@s, "ctf_team");

        if (team == 1) {
            game.blue_flag_taken = 0;
            announce("§9蓝旗 §f已归还！");
        } else {
            game.red_flag_taken = 0;
            announce("§c红旗 §f已归还！");
        }

        place_flags();
        tag_remove(@s, "has_flag");
        effect_clear(@s, "minecraft:glowing");
    }
}

可继续改进

• 添加带冷却的重生系统
• 添加职业选择（更快的旗手、更高伤害等）
• 添加在中场刷新的增益道具
• 添加旗帜自动归还计时器（例如 30 秒后归还）
