Amyue521Character* UUWebSocketGameInstance::getMyCharacher() {if (this-myCharacher ! nullptr) {return this-myCharacher;}
//获取player,并转化为Amyue521CharacterACharacter* character UGameplayStatics::GetPlayerCharacter(this-GetWorld(), 0);this-myCharacher CastAmyue521Character(character);if (this-myCharacher ! nullptr) {
//转化成功后则进行绑定JSONMessageTrigger.BindUObject(this-myCharacher, Amyue521Character::CallBackFunMul);//模拟触发这个触发实际应该放到收到message方法里执行FString TestHUDString FString(TEXT(my json msg));JSONMessageTrigger.ExecuteIfBound(TestHUDString);}return this-myCharacher;}void UUWebSocketGameInstance::OnConnected()
{UE_LOG(LogTemp, Warning, TEXT(%s), *FString(__FUNCTION__));GEngine-AddOnScreenDebugMessage(-1, 3.0f, FColor::Green, Successfully Connected);this-getMyCharacher();} 说明 这里进行了代码简化链接成功后将获取的player转化为目标Characher ACharacter* character UGameplayStatics::GetPlayerCharacter(this-GetWorld(), 0);
this-myCharacher CastAmyue521Character(character); 绑定 if (this-myCharacher ! nullptr) {JSONMessageTrigger.BindUObject(this-myCharacher, Amyue521Character::CallBackFunMul);} 触发这个触发实际应该放到收到OnMessage方法里执行 if (this-myCharacher ! nullptr) { FString TestHUDString FString(TEXT(my json msg));JSONMessageTrigger.ExecuteIfBound(TestHUDString);
}
