武器から特定の方向に銃弾を作ろうとしていますが、この弾丸は実際にはポケモンボールです。 。武器の弾丸を特定の方向に移動する方法
「弾丸」を私が望む方向に動かすことができないようです。weapon.body.velocity.x = -100; if（cursors.left.isDown） しかし、これはうまくいきませんでした。キーを押したときに画面が凍ってしまいます。
「弾丸」を私が望む方向に移動させるのを助けてください。

これを試してください。 weapon.body.velocity.x - = 100; –
@KrisJ。いずれかのキーをクリックすると、まだフリーズします。 – hannacreed
