駕駛 Chaos 車輛

匯入模型和貼圖: 將模型和貼圖匯入到引擎的Browser

這台車已經Rig了

FBX import Options:

Skeletal Mesh: turn on

Combine Meshes: If you have many separate mesh, you could turn on

Plugins:

ChaosVehiclesPlugin

WheeledVehiclePawn

Create BP:

Right click mouse > Blueprint Class

All Classes:

search: vehicle

Select “ WheeledVehiclePawn ”

Mesh > Skeletal Mesh Asset > car

攝影機

Left side > +Add > SpringArm and Camera

Do collsion test: Turn Off

輪胎設定

選上 Vehicle Movement Component

這台車有四顆輪子，所以按四次 +

Wheel Setup > Wheel Setups > +

Go to Skeleton and 拷貝骨頭名字

選骨頭 > 右鍵 > Copy selected Bone Names

Paste to Wheel setups index bone name

引擎扭力設定

Vehicle Movement component > Mechanical Setup

2種方式可以創建 扭力曲線

方法1: 點兩下扭力曲線視窗

The graph's X 軸代表引擎 RPM (每分鐘轉數)

The graph's Y軸代表引擎扭力輸出 NM (Newton Meters)

Total Tougue : 300

Add curve points in 300

Shift + 滑鼠左鍵 : Add points

曲線如圖

方法2:

滑鼠右鍵 > Miscellaneous > Curve

Pick Curve Class: CurveFloat

Add Keys

Go to BP_Car

Vehicle Movement component > Mechanical Setup

External Curve > 選上剛剛所創建的curve

Chaos Vehicle wheel Blueprint

在大多數情況下，每輛車至少需要兩種類型的車輪。.

• 一個受轉向/引擎/手煞車影響的車輪，一個不受轉向/引擎/手煞車影響的車輪

• 這可能是前輪或後輪尺寸不同的情況

Create wheel BP:

Blueprint Class > ChaosVehicleWheel

Create front and rear wheel BP

Double click BP_Front_Wheel

Setup

Wheel > Axle Type : Front

Affected by Handbrake: Turn Off

Affected by Engine: Turn on

Wheels setup

更新wheel setups class

Turn on Simulate Physics

Game Mode

Default Pawn Class: BP_Car

World Settings

Window > World Settings

GameMode Override: GM_Car

執行結果

車子物理

選擇物理並刪除

因為預設的形狀，比較不會跟車子輪胎，車體等一樣

選擇全部輪胎骨頭 > Primitive shape: Sphere >Add bodies

選擇Root 骨頭> Primitive shape: Single convex Hull >Add bodies

控制攝影機選轉

Open BP_Car

使用滑鼠來旋轉攝影機

Mouse X Axis Value ---> Delta Rotation Z

Mouse Y Axis Value ---> Delta Rotate Y

執行結果:

發現車子不是在地板上，是浮空的

改變車輪範圍

Go to BP_FrontWheel and BP_RearWheel change “ wheel radius ”

Wheel Radius: 20

Animaton

保留我們想要的車輛行為

Select car skeleton > right click mouse > Create > Anim Blueprint

Opne AnimBP > Class Settings > class options > Parent Class : Vehicle Animation Instance

Mesh Space Ref Pose: 這用於返回動畫藍圖中骨架網格物件的網格空間參考姿勢

Wheel Controller : 為了減輕創建這些類型動畫的大量工作，您可以使用滾輪控制器節點來驅動動畫。

GO to BP_Car

Select Mesh > Animation > Anim Class : AB_Car
