Hi there!
I followed this tutorial here: A new, community-hosted Unreal Engine Wiki - Announcements - Unreal Engine Forums
And made Tasks that receive a Pointer to a HierarchicalInstancedStaticMeshComponent and a Pointer to a custom Actor Component and when the Task is executed and comes to this line:
// Task properties set through constructor
UHierarchicalInstancedStaticMeshComponent * HISM;
UDataComponent * Data;
// and in DoTask
HISM->AddInstance(FTransform(Data->GetLocation(idx)));
it crashes with an “Access violation writing location” message.
I am checking both for != nullptr.
I’ve read that it could be caused by the fact that I’m not using virtual method stubs but I tried making GetLocation virtual and it didn’t fix it.
Any ideas?
UPDATE:
I split the line up into this:
// DoTask
FVector location = Data->GetLocation(idx);
FTransform transform = FTransform(location);
HISM->AddInstance(transform); // <--- Access violation writing location
And it only crashes in the last line.
EDIT:
