For custom serialized network data (UObject::NetSerialize), you can now use two new functions added to FArchive (FArchive::EngineNetVer() and FArchive::GameNetVer()) which allow you to obtain the current network version of the stream and handle old data manually.New: Build Graph Scripting ...

Arrays of array An Array of arrays is not supported in Unreal structs, a workaround is to use an array of structs that contains an array of the data type you want. The server side will need to adapt what it sends or you can decode using json fields. Conversion Most primitive types hav...
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...

Unreal Engine 4.9 游戏性编程 主要使用的容器类为 TArray。TArray 类负责同类其他对象(称为元素)序列的所有权和组织。TArray 是序列,其元素拥有定义完善的排序,其函数用于确定性地操作对象及其排序。 TArray TArray 是虚幻引擎中最常用的容器类。其设计决定了它速度较快、内存消耗较小、安全性高。TArray 类型由...
Note:Due to the way dynamic arrays are implemented, you can't pass dynamic array elements or parts of them to anoutparameter. Passing an entire dynamic array viaoutparameter is possible, and for large arrays even recommended. skip Only allowed for the second parameter of a nativeoperatordeclara...
