說明
|
|
----
|
|
|
|
粒子碰撞形狀可用於使粒子停止或對其反彈。
|
|
|
|
粒子碰撞形狀是即時的，在遊戲過程中可以移動、旋轉和縮放。與吸引器不同，碰撞形狀的非均勻縮放\ *不*\ 受支援。
|
|
|
|
粒子碰撞形狀可以通過隱藏而暫時禁用。
|
|
|
|
\ **注意：**\ 在 :ref:`GPUParticles3D<class_GPUParticles3D>` 的處理材質上，\ :ref:`ParticleProcessMaterial.collision_mode<class_ParticleProcessMaterial_property_collision_mode>` 必須是 :ref:`ParticleProcessMaterial.COLLISION_RIGID<class_ParticleProcessMaterial_constant_COLLISION_RIGID>` 或 :ref:`ParticleProcessMaterial.COLLISION_HIDE_ON_CONTACT<class_ParticleProcessMaterial_constant_COLLISION_HIDE_ON_CONTACT>`\ ，才能使碰撞生效。
|
|
|
|
\ **注意：**\ 粒子碰撞只影響 :ref:`GPUParticles3D<class_GPUParticles3D>`\ ，不影響 :ref:`CPUParticles3D<class_CPUParticles3D>`\ 。
|
|
|
|
\ **注意：**\ 由正在移動的碰撞器推動的粒子不會被插值，這可能會導致可見的卡頓。這可以通過將 :ref:`GPUParticles3D.fixed_fps<class_GPUParticles3D_property_fixed_fps>` 設定為 ``0`` 或一個符合或超過目標畫面播放速率的值來緩解。

The particle rendering layers (:ref:`VisualInstance3D.layers<class_VisualInstance3D_property_layers>`) that will be affected by the collision shape. By default, all particles that have :ref:`ParticleProcessMaterial.collision_mode<class_ParticleProcessMaterial_property_collision_mode>` set to :ref:`ParticleProcessMaterial.COLLISION_RIGID<class_ParticleProcessMaterial_constant_COLLISION_RIGID>` or :ref:`ParticleProcessMaterial.COLLISION_HIDE_ON_CONTACT<class_ParticleProcessMaterial_constant_COLLISION_HIDE_ON_CONTACT>` will be affected by a collision shape.
|
|
|
|
After configuring particle nodes accordingly, specific layers can be unchecked to prevent certain particles from being affected by colliders. For example, this can be used if you're using a collider as part of a spell effect but don't want the collider to affect unrelated weather particles at the same position.
|
|
|
|
Particle collision can also be disabled on a per-process material basis by setting :ref:`ParticleProcessMaterial.collision_mode<class_ParticleProcessMaterial_property_collision_mode>` on the :ref:`GPUParticles3D<class_GPUParticles3D>` node.
