我没有办法把Entity 中的fragment 数据初始化成我想要的数据

Hi there @losep0

Inside your for (int32 i = 0; i < EntityTypes.Num(); i++) loop, you have: ‘Transforms.Transforms’. But you’re missing adding transforms for your spawned entities. You need to add Count number of transforms to it, based on your Owner’s transform or your own logic.

谢谢你的帮助，这个是现在代码的样子 ，我想要在这个阶段初始化entity的其它Fragment我应该怎么做

#include "MassSpawnLocationProcessor.h"
#include "MassSpawnerTypes.h"
#include "MoveToTargetProcessor.h"
#include "MassEntityConfigAsset.h"
#include "MassEntitySpawnDataGeneratorBase.h"
#include "MoveTargetTrait.h"
#include "ThisLocalSpawn.generated.h"

Did this fix the issue?

是的，但是我有其他的fragment 想要在这进行初始化我应该怎么办
