Upgrade to UE5.5 throwing errors regarding the use of native pointers.

[MicahHodge]

I am upgrading my project from 5.3 to 5.5 and when I attempt to compile the project i see many errors regarding the use of native pointers.

Native pointer usage in member declaration detected [[[class UAnimMontage*]]].  This is disallowed for the target/module, consider TObjectPtr as an alternative.

I have verified the config for the UnrealHeaderTool and I believe this should not be happening. Also, when I attempt to build for UE5.4 I do not see these errors. Anyone seen this before?

I’m also seeing this, have you had any luck getting it to build?

It’s just required now, update your pointers from:
MyPointerType* VariableName
to
TObjectPtr<MyPointerType> VariableName

It’s a lot of find and replace, but a simple update.

TObjectPtr can represent a reference as a handle. That means it opens some options for lazy loading (but editor only, packaged game remains unchanged). When this TObjectPtr/FObjectPtr is seen it does not necessarily need to be resolved at the same time. It can be kept around as a handle and resolved later, when really needed. Look for LazyOnDemand and TODO: OBJPTR in the engine source. It seems to be tied to TObjectPtr. In 5.0, USoundWaves have meta=(LoadBehavior = “LazyOnDemand”) I saw it us…
