Set world rotation accessed none reading pawn return but print string works at getting the co-ords?

Hi, I am trying to set up a turret that follows and fires at the player pawn but the Set world rotation node is always erroring with a no return value from the pawn. The print string is picking up the co-ords no problem?

Can anyone tell me why this is happening and give me a nudge in the right direction.

Thanks.

Are you sure your printString is working fine? I ask, because it is showing an error as well. Us an IsValid node, the one with a ?, and plug in the get player pawn to it. On isValid call the update rotation function. If it fails print a string saying Not Valid or something like that. That should clearly identify the problem. Also, not sure what release you are using, but you can call, getWorldDeltaSeconds now. You don’t need to set the delta. Older tutorials show that quite often because the node didn’t exist…or maybe it did and we didn’t know?

The ?Isvalid node solved the issue, thank you very much James!
