構造体を波カッコで初期化

構造体の宣言

    struct GateMaster {
        int gateId;
        int stageId;
        int nextGateId;
        int x;
        int y;
        GateType gateType;
    };

変数の宣言

const static std::map<int, GateMaster> DUMMY_GATE_MASTER_LIST;

初期化

const std::map<int, Gate::GateMaster> Gate::DUMMY_GATE_MASTER_LIST = {
    {1, {1, 1, 2, 100, 100, Gate::GateType::NORMAL_V}},
    {2, {2, 2, 1, 200, 100, Gate::GateType::NORMAL_V}},
    {3, {3, 2, 4, 300, 100, Gate::GateType::NORMAL_V}},
    {4, {4, 3, 3, 400, 100, Gate::GateType::NORMAL_V}},
    {5, {5, 3, 7, 500, 100, Gate::GateType::NORMAL_V}},
    {6, {6, 3, 8, 600, 100, Gate::GateType::NORMAL_V}},
    {7, {7, 4, 5, 700, 100, Gate::GateType::NORMAL_V}},
    {8, {8, 5, 6, 800, 100, Gate::GateType::NORMAL_V}},
};
