Endless Runner Problem with spawning Tiles & character

i had many problem with the BP_floortile and the character both are not spawning first of all and then theBP_floortile is also not looping i have given all the function in the endless runner tutorial!! pls help me!!!
pls check the error

Hello,

Could you post a screenshot of the blueprint(s) that you are having an issue with? I’d like to compare what you have to what I have in my Endless Runner project. Thank you.

pls check the youtube video link in the question

I noticed that in your AddFloorTile function located in your RunGameMode, you did not Cast To BP_Floor Tile after the Spawn Actor BP_FloorTile node. Without getting the transform of the next tile, you would just be spawning all of the floor tiles in the same place. For reference, this is the point in the video where I noticed a difference in your AddFloorTile function: Endless Runner: Spawning the Course | 02 | v4.7 Tutorial Series | Unreal Engine - YouTube

I delete that because i got an error so i reffered this link below and then i removed and my error was solved

which version of UE was used for the tutorial

What error were you getting when you followed the tutorial? Did you ensure that you had your annotations on for the Youtube video, as they will occasionally pop up and provide information regarding changes that you will need to make to your project.

its a big mess system is crashing any way i’m starting again with UE4.7 PLEASE help me again if error comes again,thanks for ur response
