Hello friends! ))) Thx to u Rick and for your courses ! I have a problem with transform x and when I set parent spawner 0 0 0 my child spawners are gone out from my game . To be honest everything was fine but as Rick said in video “if you have different transform from Rick you will have null reference” as i had later. After that I messed up transform position all game objects. Please help. (((
Sorry forgot that null reference brings my to eror with line
if (myLaneSpawner.trasnform.childCount <= 0)
Hi Orxan,
Thanks for posting the line which causes the error. That’s helpful.
Check where a lane gets assigned to the myLaneSpawner
variable. The y-coordinates of both the defender and the spawner must be equal. Otherwise, the condition gets evaluated to false, and nothing gets assigned to myLaneSpawner
. If the variable is empty, it is null
, thus the NullReferenceException.
Did this help?

Hi Nina ! Thx to you as always ))). I want to check if i understand u correctly. I must return cactus prefab an lizard prefab in game cause i deleted them as Rick did. Then i must put them in a same lane ??? Sorry for dumb questions ))) i a very beginner )))
And i just remembered that after i did eveything like Rick in lesson 152 and i got null reference. I have messed transform position of game canvas game camera. I tried to set x y position as Rick had but everything got wrong. but i managed to set cactus in a write lane but lizard spawners dont match with cactus position (((
Oh Nina i ve just managed to make them y equal position. but i still have an issue with the same line of code that i mentioned and that eror for some reason tags cactus>body ((
Yes I did it i have win the null reference ))) and theres no null reference buuuut))) my cactus now is a little bit out from square . I reset body of cactus to 0 .0. 0 know i need to restore cactus position with out getting null reference ))) any suggestions ? )
Nina Hello again ))) forgive me for writting so much ))). Nina I did it all )) I have won )) Thx to you for helping me !!! The problem was that a had to remove a shooter script from cactus body )). A saw that solution in one of your topics ))) But could u be so kind to explain why i had to remove shooter script from cactus body and Rick hadnt?? ))) Thank u again Nina
My apologise Rick doesnt have a shooter script in a cactus body ))) Thank you Nina for helping ))) You and your crew are the best ))
Good job on fixing the issue yourself, @Orxan_rzaev!
The Cactus Body probably did not have the same y-position as one of the spawners. In that case, no spawner was found because our condition is: If y-position of shooter equals y-position of spawner, then assign spawner to myLaneSpawner
. Without knowing much about your project, that’s just a guess, though.
