Blueprint not being called???

[anonymous_user_9c565d7f]

Does anyone know why this isn’t being called? it’s connected to an ‘event beginplay’ straight into the ‘cast to magiccharacter’ so by all rights should be called? surely?? no? wat?

i placed a print string at the end and it doesnt get called. I placed one just after ‘cast to magiccharacter’ and it doesnt get called. i place one just before the ‘cast to magiccharacter’ and it does get called?

it seems it’s something to do with the cast but i just can’t figure it out, the solution defininately isn’t obvious. I’ve spent a good 7-8 hours diagnosing bugs and this one just won’t budge.

any input would be appriciated as i’m this close ( - ) to scrapping the whole thing.

thanks

Have you dropped the blueprint in the world?
And hook up a print string to cast failed to see if the cast is failing.

That case is already covered with 3 PrintStrings (one before cast / two after).
Its more likely Get-Player-Character is null at the time the Cast is executed…
Actors not instantiated yet / complex dependencies / different startup-orders…
This is a common problem… PIE-Editor vs Packaged-games vs Multiplayer.
Easy solution is add an ‘IsValid’ node. If it fails, loop-back a wire on a Delay…

I will try this soon, the actor is instantiated, i even added a few second delay after beginplay to ensure that, but ill try the isValid thing soon.

Interesting!!! In that case, here are three other possibilities to ask yourself maybe.
Are you doing something elsewhere that would ‘destroy’ the Player Character???

A. Loading / Opening a level (every reference is lost - unless its stored in game-instance).
B. Hooking up a DestroyActor in the Graph, that you wrongly assumed wouldn’t get called.
C. You’ve created more than one instance of the Character by accident (really easy to do).

BTW:
If none of that helps do a last minute ‘idiot check’ to ensure Get-Player-Character is actually of class MagicCharacter and not Magic-Character or Magic_Character or Magic-Character1 or Magic_Character1 or MagicCharacter2. (Add a Print-String on Get-Player-Character). Also check Project Settings -> Maps & Modes -> Default Pawn Class has been set correctly, and not to something else. When you spend hours on the same problem, its not unusual for the brain to turn to mush and then you miss the obvious…

I’ve only just got back to this project, turns out you where right! The player wasn’t being instantiated but the blueprint was calling it.

Here was the problem:

I have a character selection menu where you can choose between a few characters. before you choose a character, there are no characters in the level that can be called by the blueprint.

However, as the blueprint is being called on BeginStart, it was being called before a character had been selected, therefore couldn’t find a character. If that makes sense

Thanks a ton man.
