I have my game setup so the AI chases the player on sight (AI Perception). When they “Hit” the player, it causes damage until the player is literally destroyed (Destroy Actor). They do not reset and begin wandering around again. They just stand there where the player last was and spit out this error like there is no tomorrow:
Blueprint Runtime Error: “Accessed None trying to read property CallFunc_GetPlayerCharacter_ReturnValue”. Blueprint: GetPlayerLocationTut Function: Execute Ubergraph Get Player Location Tut Graph: EventGraph Node: Set Blackboard Value as Vector
The best I can tell, with the player destroyed, there is no valid vector update, so they stand there and look stupid. If is zip around a corner and out of sight, they revert to wandering around.
Try hooking an Is Valid node up to the get player character node. Run the Is Valid node first, then proceed to the rest of the code if it is true.
You can also pull the wire off of the “false” part of the Is Valid and set where you want the AI to go if your character has been destroyed. (Maybe have the AI make a starting location variable at some point and simply return to that point upon the player character being destroyed?)
I will give that a shot once I finish placing lights. Now that is a fun tie.
That got rid of the errors!!! Thanks a million!!!
