Gizmo breaks when a matrix of object that has parents is using in ImGuizmo::Manipulate.

[pfhgil]

I am passing the final matrix of an object that has parents to function ImGuizmo::Manipulate.

finalModelMatrix = allParentsModelMats * modelMatrix;

When scaling the parent object, and then manipulating the child object, my entire gizmo breaks.

Please fix this hurtful misunderstanding :(. And thanks for the wonderful library!

Bro, u can do this fix it!

if (selectObj != nullptr)
{
	float* matrix = MMath::XMMatrixToFloatArray(selectObj->transform->GetWorldMatrix());
	(ImGuizmo::Manipulate(
		cameraView,
		cameraProjection,
		mCurrentGizmoOperation,
		mCurrentGizmoMode,
		matrix,
		NULL,
		NULL,
		NULL,
		NULL
	));
	{
		auto newMatrix = MMath::FloatArrayToXMMatrix(matrix);

		auto localMatrix = newMatrix;
		
		if(selectObj->transform->parent != nullptr)
			localMatrix = newMatrix * XMMatrixInverse(nullptr,selectObj->transform->parent->GetWorldMatrix());


		XMVECTOR nScale;
		XMVECTOR nRot;
		XMVECTOR nTrans;

		XMMatrixDecompose(&nScale, &nRot, &nTrans, localMatrix);

		XMFLOAT3 scaleF3;
		XMFLOAT4 rotF4;
		XMFLOAT3 transF3;

		XMStoreFloat3(&scaleF3, nScale);
		XMStoreFloat4(&rotF4, nRot);
		XMStoreFloat3(&transF3, nTrans);

		selectObj->transform->SetLocalPosition(transF3);
		selectObj->transform->SetLocalRotation(rotF4);
		selectObj->transform->SetScale(scaleF3);
	}
