私のプロジェクトで連絡先を検出する必要がありますが、連絡先を検出したいと思う9つの四角形があります。 9種類の物理学のボディを作成せずに接触を検出する方法がありますか、または物理的なボディの配列のようなものです。また、円が四角形に接触するたびに、その四角が色に変わります。私はこれのような配列のようにしたい：多くのSKSpritenodesとSKSpritenodeの接触を検出するSwift
for i in 1...9{
if firstBody.categoryBitMask == PhysicsCategory.square[i] && secondBody.categoryBitMask == PhysicsCategory.circle || firstBody.categoryBitMask ==
PhysicsCategory.circle && secondBody.categoryBitMask == PhysicsCategory.square[i] {
squares[i].node.color = squares[i].targetColor
//this is my array of structs containing the skspritenodes
squares[i].colorBlendFactor = 1.0
}
}
私は9つの物理機関を作ろうとしましたが、私は多くのエラーがあります。これは私がこれまで行ってきたことです。
