Press 'U' makes the game chrash

Hello,

I have a problem. When I press U the game and ark dev kit chrashes. In the hud I didnt changed anything to the wistle widget. I modified some dino, which dont have a AI controller, can this be the problem?

Has anybody else this problem? How do I fix this?

Thank you in advance!

Isn’t U default key to follow command? If you have a Dino without an AI controller then it might just crash the game if you try to get it to follow you.

Have you tried without the “modified some Dino”?

Even if I don’t spawn this dino, it chrashes so I don’t know if that could be the problem.

It might as well be as the Devkit could load the dino even though you are not spawning it.

Okay, I will try that

No ,I added to all my dino’s the default AI controller, I only set wander to false and set the attack behaviour tree to none. I still get this error:
Fatal error!

What is the problem? Is there some-one who has experience with this?

The dino’s ae not the problem. I played the default gamemode and spawned in a modded dino and no chrash. So I think it is something with the playercontroller ot the PrimalGamedata. Does someone knows what settings in these blueprint can cause the crash?

Someone who knows it?

I checked my primalgamedata and playercontroller, but I couldn’t find a difference.

I think I’ve had a similar crash when my UDK tried to call a function from the weather system I copied over. It might be that the U command tries to call some kind of a function in a blueprint which it cannot find. You should try to check the references in your bp’s. See if they are all set and nothing has a yellow warning flag.

I checked several blueprint, but they all have a green marker. The error says something about shootercharacter and shooter playercontroller, what exactly is wrong with these two?

All you can do so verify your install in Epic launcher and copy back your files from the backup folder one by one until you identify the file you messed on.

It’s probably your player controller or pawn files. Maybe you accidently changed a field that calls some blueprint… or added some scripting relating to a tamed dino stay event that is wrong.

Found the problem! When you press U it calls a animation, I changed the character mesh, so the animation could not be called correctly, so the game chrashed.
