如何添加资产

本文档尚在编写中，可能不完整。

添加车辆

按照 艺术指南 创建骨架网格体和物理资产。 其余部分请参阅 车辆用户指南 。

  • 将 fbx 作为 Skelletal Mesh 导入到其自己的文件夹中 Content/Static/Vehicles。物理资产和骨架应自动创建，并将三者链接在一起。
  • 调整物理资产。删除自动创建的资产，并为与Vehicle_Base形状匹配的骨骼添加框，确保启用了生成撞击事件。为每个轮子添加一个球体，并将其“物理类型”设置为“运动学”。
  • 在该文件夹中创建一个“动画蓝图”，创建时选择“VehicleAnimInstance”作为父类，并以此汽车模型的骨架作为目标骨架。添加动画图，如上面给出的链接所示（或在其他汽车的动画中查找，如 Mustang）。
  • 创建文件夹Content/Blueprints/Vehicles/<vehicle-model>
  • 在该文件夹中，创建两个从“VehicleWheel”类派生的蓝图类。将它们命名为<vehicle-model>_FrontWheel和<vehicle-model>_RearWheel。将它们的“形状半径”设置为与网格轮半径完全匹配（注意，是半径而不是直径）。将它们的“轮胎配置”设置为“CommonTireConfig”。在前轮上取消选中“受手刹影响”，在后轮上将“转向角”设置为零。

  • 在同一个文件夹中创建一个蓝图类，从中派生出并BaseVehiclePawn调用它<vehicle-model>。打开它进行编辑并选择组件“Mesh”，将“Skeletal Mesh”和“Anim Class”设置为相应的。然后选择组件“VehicleMovement”，在“Vehicle Setup”下展开“Wheel Setups”，设置每个车轮

  • 0：轮子类别= <vehicle-model>_FrontWheel，骨骼名称=Wheel_Front_Left

  • 1：轮子类别= <vehicle-model>_FrontWheel，骨骼名称=Wheel_Front_Right
  • 2：轮子类别= <vehicle-model>_RearWheel，骨骼名称=Wheel_Rear_Left

  • 3：轮子类别= <vehicle-model>_RearWheel，骨骼名称=Wheel_Rear_Right

  • 向其中添加一个名为“Box”的盒子组件（参见 Mustang 蓝图），并将大小设置为从上方覆盖车辆区域。确保设置了以下内容

  • 隐藏在游戏中
  • 模拟物理已禁用
  • 禁用生成重叠事件
  • 碰撞预设设置为“NoCollision”

测试一下，进入 CarlaGameMode 蓝图并将“Default Pawn Class”更改为新创建的汽车蓝图。

地图生成

对于道路生成，预计会找到以下网格
