首先在Unreal Engine中下载好Niagara以及Niagara Fluids插件,在Content Drawer中右键选择Niagara System,选择New system from a template or behavior example,再点击左边的Templates,选择Grid 3D Gas Smoke,右键Edit就可以打开这个蓝图了(或者也可以放在一个Level里面去,这样还可以看见User控制的参数),我自己是先从这个例子...
UObject* UNormalDistributionFactory::FactoryCreateNew(UClass* Class, UObject* InParent, FName Name, EObjectFlags Flags, UObject* Context, FFeedbackContext* Warn) { return NewObject<UNormalDistribution>(InParent, Class, Name, Flags, Context); } UNormalDistributionFactory 确实派生自 UObject,因此...
并且UObject类实现了一套完善的反应以及检查系统,相比之下如果游戏开发者自己去实现类似功能细节则会带来很多不必要的开销,并且代码在经过大规模测验之前可能包含潜在的安全隐患。 Engine: Engine模块是虚幻引擎的大部分实际工作发生的地方;它是各种游戏相关的功能的集合,这些功能比Core“使用原生代码更合适”的代码更加具...
点击Compile并关闭SpawnTunnelAtSpawnPoint图表,随后打开BP_Tunnel。 添加新变量,命名为TunnelSpawner,将Variable Type类型设置为BP_TunnelSpawner\Object Reference。 点击Compile并切换回BP_TunnelSpawner。 打开SpawnTunnel图表添加对应节点: 现在,每个隧道都能获得BP_TunnelSpawner的引用。 接着,我们要让BP_TunnelSpawner能...

UnrealEngine创建自定义资产类型 导语 这篇文章记录了将UObject实例保存在Asset文件的方法,用这个方法可以将自定义的UObject数据序列化保存到文件,可以用于自定义UE资源类型。 创建UObject类 这一步比较简单,按照正常的方式创建C++类即可。 在这里我创建一个简单的UCustomAsset派生自UObject,包含一个Value字段作为演示。
parent_to_snap (ControlRigSnapperSelection)– The parent object to snap relative to. If animated, it needs to live in an active Sequencer in the level editor snap_settings (ControlRigSnapSettings)– Settings to use time_unit (SequenceTimeUnit)– Unit for frame values, either in display rate...

As a side note, object properties are also not exposed for the same reason. The Blueprint details view for non-member variables (either from a parent class or an external member reference), will no longer show uneditable options as editable. ...
Typical Unreal Engine game code is expressed as Actor objects that inherit from parent classes to change their data and functionality based on what they are. In an ECS, an entity is only composed of fragments that get manipulated by processors based on which ECS components they have....
