【1.7.10】新しい弓矢の追加について

投稿記事by ShuperDark » 2017年9月17日(日) 15:42

最近質問が多くなってきてしまい、大変申し訳ございません...PC版のModdingが楽しくなってきたもので...

それで、海外の方の動画や、解説しているサイトを参考にしながら新しい弓矢のエンティティ、レンダラーを追加してみたんですけど(ほとんど参照ライブラリのForgeのソースコードのコピペですが)、動作的にはあまり問題はないのですが、地面のブロックと接触したときに、新しい弓矢の見た目が浮いてしまいます(または10秒後ほど経って浮いたり...)

[url=https://www.dropbox.com/s/612mn804zn1jo3i/スクリーンショット%202017-09-17%2014.52.43.png?dl=0][img]https://dl.dropboxusercontent.com/s/612mn804zn1jo3i/スクリーンショット%202017-09-17%2014.52.43.png[/img][/url]

実体自体はしっかりブロックと接触したところに存在しているのですが、見た目が不適切な感じです(説明不足で本当に申し訳ないです)
どうかこんな私にご教授お願いいたします!
また、その新しい弓矢の飛行速度を変えたいのですが、その場合はどこを弄ればよいのでしょうか...

Re: 【1.7.10】新しい弓矢の追加について

投稿記事by defeatedcrow » 2017年9月17日(日) 23:18

ShuperDark さんが書きました:最近質問が多くなってきてしまい、大変申し訳ございません...PC版のModdingが楽しくなってきたもので...

それで、海外の方の動画や、解説しているサイトを参考にしながら新しい弓矢のエンティティ、レンダラーを追加してみたんですけど(ほとんど参照ライブラリのForgeのソースコードのコピペですが)、動作的にはあまり問題はないのですが、地面のブロックと接触したときに、新しい弓矢の見た目が浮いてしまいます(または10秒後ほど経って浮いたり...)

[url=https://www.dropbox.com/s/612mn804zn1jo3i/スクリーンショット%202017-09-17%2014.52.43.png?dl=0][img]https://dl.dropboxusercontent.com/s/612mn804zn1jo3i/スクリーンショット%202017-09-17%2014.52.43.png[/img][/url]

実体自体はしっかりブロックと接触したところに存在しているのですが、見た目が不適切な感じです(説明不足で本当に申し訳ないです)
どうかこんな私にご教授お願いいたします!
また、その新しい弓矢の飛行速度を変えたいのですが、その場合はどこを弄ればよいのでしょうか...

●描画上で1ブロックほど戻る現象は、サーバとクライアントでの座標のズレ(ラグ)の問題じゃないかと思います
コレに関しては私自身克服を諦めたので、憶測になりますが…

手元に生きている1.7環境がないので推測ですが、その矢Entityを登録しているメソッドってたしか、
コード: 全て選択
EntityRegistry.registerModEntity(Class Entityのclass, String "名前", int ID, Class Modクラス,
            int 描画範囲, int 更新Tick頻度, boolean Verocity用パケット送信の有無);

こんな感じですよね
このうち更新頻度Tickっていくつになっていますか
これを1にしたりして、改善しませんかね?

だめそうなら、刺さった場合にサバクラで位置合わせをする独自メソッドか何かの開発が必要そうですね…

●速度の変更についてですが
初速度を変える場合は、初期速度としてコンストラクタで入力されています
ですので、このソース内にはありません。弓(ItemBow)の発射処理の方で算出されています
(弓って、タメ時間によって矢の飛距離が変わりますよね、なので弓側が受け持っているんだと思います)
そちらの処理に、生成した矢に対してsetThrowableHeadingメソッドあたりで速度を付与していると思うので確認してみてください

矢のEntityクラス側でいじる場合も、setThrowableHeadingメソッドを書き換える(引数に渡ってきたvelocityの値や、計算内容などをいじってみる)で変更できると思います
ただしこのメソッドは方向のベクトルの初期値計算も負っているので、弄り間違えると変な方に矢が飛んで行くので気をつけてください

Re: 【1.7.10】新しい弓矢の追加について

投稿記事by ShuperDark » 2017年9月18日(月) 14:06

defeatedcrow さんが書きました:
ShuperDark さんが書きました:最近質問が多くなってきてしまい、大変申し訳ございません...PC版のModdingが楽しくなってきたもので...

それで、海外の方の動画や、解説しているサイトを参考にしながら新しい弓矢のエンティティ、レンダラーを追加してみたんですけど(ほとんど参照ライブラリのForgeのソースコードのコピペですが)、動作的にはあまり問題はないのですが、地面のブロックと接触したときに、新しい弓矢の見た目が浮いてしまいます(または10秒後ほど経って浮いたり...)

[url=https://www.dropbox.com/s/612mn804zn1jo3i/スクリーンショット%202017-09-17%2014.52.43.png?dl=0][img]https://dl.dropboxusercontent.com/s/612mn804zn1jo3i/スクリーンショット%202017-09-17%2014.52.43.png[/img][/url]

実体自体はしっかりブロックと接触したところに存在しているのですが、見た目が不適切な感じです(説明不足で本当に申し訳ないです)
どうかこんな私にご教授お願いいたします!
また、その新しい弓矢の飛行速度を変えたいのですが、その場合はどこを弄ればよいのでしょうか...

●描画上で1ブロックほど戻る現象は、サーバとクライアントでの座標のズレ(ラグ)の問題じゃないかと思います
コレに関しては私自身克服を諦めたので、憶測になりますが…

手元に生きている1.7環境がないので推測ですが、その矢Entityを登録しているメソッドってたしか、
コード: 全て選択
EntityRegistry.registerModEntity(Class Entityのclass, String "名前", int ID, Class Modクラス,
            int 描画範囲, int 更新Tick頻度, boolean Verocity用パケット送信の有無);

こんな感じですよね
このうち更新頻度Tickっていくつになっていますか
これを1にしたりして、改善しませんかね?

だめそうなら、刺さった場合にサバクラで位置合わせをする独自メソッドか何かの開発が必要そうですね…

●速度の変更についてですが
初速度を変える場合は、初期速度としてコンストラクタで入力されています
ですので、このソース内にはありません。弓(ItemBow)の発射処理の方で算出されています
(弓って、タメ時間によって矢の飛距離が変わりますよね、なので弓側が受け持っているんだと思います)
そちらの処理に、生成した矢に対してsetThrowableHeadingメソッドあたりで速度を付与していると思うので確認してみてください

矢のEntityクラス側でいじる場合も、setThrowableHeadingメソッドを書き換える(引数に渡ってきたvelocityの値や、計算内容などをいじってみる)で変更できると思います
ただしこのメソッドは方向のベクトルの初期値計算も負っているので、弄り間違えると変な方に矢が飛んで行くので気をつけてください



うーん・・・
色々奮闘してみたんですが、どうも描画についてはダメそうです・・・
とりあえず飛行速度については納得のいくように変更できました。ありがとうございました。
