英文:
Why may StaticMeshComponent not move around in UnrealEngine?
问题
I use the Character C++ class to move the character in my game via AddInputMovement().
However, it only moves if there's no MeshComponent attached to it. If I attach StaticMeshComponent, it stops reacting to any keys and moving, while if I attach a common MeshComponent, it requires a Skeletal mesh in Blueprint Editor, although my spaceship .fbx model is not one.
What should I do? What are the reasons a StaticMesh might refuse to move?
ASpaceship::ASpaceship()
{
PrimaryActorTick.bCanEverTick = true;
// !!! These lines prevent the character from moving for some reason...
MeshComponent = CreateDefaultSubobject<UStaticMeshComponent>(TEXT("MeshComponent"));
RootComponent = MeshComponent;
}
请注意，代码部分已被保留，没有进行翻译。

Static Mesh Components (UStaticMeshComponent),就像从USceneComponent继承的任何其他组件一样，如果它们的Mobility属性设置为"Moveable"（EComponentMobility::Type::Moveable），它们可以移动。
为确保您添加到角色的网格组件将与角色一起移动，您需要确保以下几点：
- 它被设置为可移动：
YourMeshComponent->Mobility = EComponentMobility::Movable; - 它附加到角色的根组件：
YourMeshComponent->AttachToComponent(YourActor->GetRootComponent(), FAttachmentTransformRules::SnapToTargetNotIncludingScale);。
注意：在代码中，将YourActor替换为您的角色，将YourMeshComponent替换为您的网格。
现在，对您的角色的任何变换更改都将应用于该网格。
英文:
Static Mesh Components (UStaticMeshComponent), just like any other component inheriting from USceneComponent, can and do move, if their Mobility property is set to "Moveable" (EComponentMobility::Type::Moveable).
To make sure the mesh component you added to the actor will move together with your actor, you need to make sure of several things:
- It is set to moveable:
YourMeshComponent->Mobility = EComponentMobility::Movable; - It is attached to the actor's root component:
YourMeshComponent->AttachToComponent(YourActor->GetRootComponent(), FAttachmentTransformRules::SnapToTargetNotIncludingScale);.
Note: in the code, replace YourActor is your actor and YourMeshComponent is your mesh.
Now, any changes to your actor's transform will be applied to the mesh.
