Descripción
|
||
----------------------
|
||
|
||
A real-time heightmap-shaped 3D particle collision shape affecting :ref:`GPUParticles3D<class_GPUParticles3D>` nodes.
|
||
|
||
Heightmap shapes allow for efficiently representing collisions for convex and concave objects with a single "floor" (such as terrain). This is less flexible than :ref:`GPUParticlesCollisionSDF3D<class_GPUParticlesCollisionSDF3D>`, but it doesn't require a baking step.
|
||
|
||
\ **GPUParticlesCollisionHeightField3D** can also be regenerated in real-time when it is moved, when the camera moves, or even continuously. This makes **GPUParticlesCollisionHeightField3D** a good choice for weather effects such as rain and snow and games with highly dynamic geometry. However, this class is limited since heightmaps cannot represent overhangs (e.g. indoors or caves).
|
||
|
||
\ **Note:** :ref:`ParticleProcessMaterial.collision_mode<class_ParticleProcessMaterial_property_collision_mode>` must be ``true`` on the :ref:`GPUParticles3D<class_GPUParticles3D>`'s process material for collision to work.
|
||
|
||
\ **Note:** Particle collision only affects :ref:`GPUParticles3D<class_GPUParticles3D>`, not :ref:`CPUParticles3D<class_CPUParticles3D>`.

An update can be forced by slightly moving the **GPUParticlesCollisionHeightField3D** in any direction, or by calling :ref:`RenderingServer.particles_collision_height_field_update()<class_RenderingServer_method_particles_collision_height_field_update>`.

If ``true``, the **GPUParticlesCollisionHeightField3D** will follow the current camera in global space. The **GPUParticlesCollisionHeightField3D** does not need to be a child of the :ref:`Camera3D<class_Camera3D>` node for this to work.
|
||
|
||
Following the camera has a performance cost, as it will force the heightmap to update whenever the camera moves. Consider lowering :ref:`resolution<class_GPUParticlesCollisionHeightField3D_property_resolution>` to improve performance if :ref:`follow_camera_enabled<class_GPUParticlesCollisionHeightField3D_property_follow_camera_enabled>` is ``true``.

The visual layers to account for when updating the heightmap.

By default, all 20 user-visible layers are taken into account for updating the heightmap collision.
|
||
|
||
\ **Note:** Since the :ref:`heightfield_mask<class_GPUParticlesCollisionHeightField3D_property_heightfield_mask>` allows for 32 layers to be stored in total, there are an additional 12 layers that are only used internally by the engine and aren't exposed in the editor. Setting :ref:`heightfield_mask<class_GPUParticlesCollisionHeightField3D_property_heightfield_mask>` using a script allows you to toggle those reserved layers, which can be useful for editor plugins.
|

|
||
To adjust :ref:`heightfield_mask<class_GPUParticlesCollisionHeightField3D_property_heightfield_mask>` more easily using a script, use :ref:`get_heightfield_mask_value()<class_GPUParticlesCollisionHeightField3D_method_get_heightfield_mask_value>` and :ref:`set_heightfield_mask_value()<class_GPUParticlesCollisionHeightField3D_method_set_heightfield_mask_value>`.

Higher resolutions can represent small details more accurately in large scenes, at the cost of lower performance. If :ref:`update_mode<class_GPUParticlesCollisionHeightField3D_property_update_mode>` is :ref:`UPDATE_MODE_ALWAYS<class_GPUParticlesCollisionHeightField3D_constant_UPDATE_MODE_ALWAYS>`, consider using the lowest resolution possible.
