Shape module
This module defines the shape (the volume or surface) from which particles can be emitted, and the direction of the start velocity. The options available vary depending on the Shape you choose - Cone and Mesh have slightly different menu options.
プロパティー
| プロパティー | 機能 |
|---|---|
| Shape | 放出するボリュームの形状 |
| Sphere | すべての方向への均一的な放出 |
| Hemisphere | 平面の片面上ですべての方向への均一的な放出 |
| Cone | Emission from the base or body of a cone. The particles diverge in proportion to their distance from the cone’s centre line. |
| Box | Emission from the body of a box shape. The particles move in the emitter object’s forward (Z) direction. |
| Mesh | Emission from any arbitrary Mesh shape supplied via the Inspector. Mesh contains an extra menu to select whether particles are emitted from the vertices, triangles or edges of the Mesh. |
| MeshRenderer | ゲームオブジェクトのメッシュレンダラーへの参照からの放出 |
| SkinnedMeshRenderer | ゲームオブジェクトのスキンメッシュレンダラーへの参照からの放出 |
| Circle | Uniform emission from the centre of edge of a circle. The particles move only in the plane of the circle. |
| Edge | 線分からの放出。パーティクルは放出するオブジェクトを上 (Y) の方向に移動します。 |
|
Angle (Cone only) |
円錐の角度。0 は円柱形を、90 ではディスクのような平らな形になります。 |
|
Radius (Sphere, Hemisphere, Cone, Circle and Edge only) |
形状の円の半径 |
|
Length (Cone only, when using one of the volume Emit from modes) |
The length of the cone. |
|
Box X, Y, Z (Box only) |
ボックス形状の幅、高さ、深さ |
|
Mesh (Mesh, MeshRenderer and SkinnedMeshRenderer only) |
エミッターの形状を提供するメッシュ |
|
Emit from Shell (Sphere and Hemisphere only) |
有効にすると、パーティクルを形状の内部ボリュームからではなく、外側の表面から放射します。 |
|
Emit from (Cone only) |
放出する、円錐の部分を Base, Volume, Base Shell ,Volume Shell から選択します。 |
|
Arc (Circle only) |
放出の形状を作る円弧 |
|
Emit From Edge (Circle only) |
Enable this to make particles be emitted from the edge of the circle rather than the centre. |
| Single Material | パーティクルを特定のサブメッシュ (マテリアルインデックス番号で確認) から放出するか。有効にすると、番号のフィールドが表示され、マテリアルインデックス番号を指定できます。 |
| Use Mesh Colors | メッシュカラーを使用するか、無視するかを決定します。 |
| Normal Offset | パーティクルを放出するためのメッシュの表面からの距離 (表面法線の方向) |
| Align to Direction | This will cause particles to be rotated based on their initial direction of travel. To apply a custom rotation direction on top of this setting, configure the Start Rotation setting in the Main module. |
| Random Direction | When enabled, the particles’ initial direction will be chosen randomly. |
詳細
All the shapes except Mesh have properties that define their dimensions (such as Radius). These can be edited by dragging the handles on the wireframe emitter shape in the Scene view. The choice of shape affects the region from which particles can be launched but also the initial direction of the particles. For example, a Sphere emits particles outward in all directions, a Cone emits a diverging stream of particles, and a Mesh emits particles in directions that are normal to the surface.
Align to Direction
Use this checkbox to orient particles based on their initial direction of travel. This can be useful if you want to simulate, for example, chunks of car paint flying off a car’s bodywork during a collision. If the orientation is not satisfactory, you can also override it by applying a Start Rotation value in the Main module.
Mesh shape source
Skinned Meshes can be used as a source for a particle emitter. Additionally, MeshRenderer types are supported. Simply assign the Mesh instance in the Shape module to have particles emit from the surface of an instantiated Mesh.
It is possible to choose to emit only from a particular material (sub-Mesh), and to offset the emission position along the Mesh’s normals. This option allows users to offset particles from the surface of a Mesh.
It is also possible to ignore the color of the Mesh.
