It finally worked, i managed to correct my mistakes, the names are now matched and it's working. Thank you RyiSnow :)

Ok thanks, sorry for not responding before, i was taking a break from work and stuff, but i'll go check it. Thanks for answering me :)

Thanks for answering me, however i verified my checkObject method and apparently, there is nothing wrong, well at least, i didn't see my mistake, but i swear, i checked it twice and nothing appears to be wrong.

Hello RyiSnow! Could you help me, please? i'm stuck at part 28 in your 2D game tutorial, basically my character is not picking up the key, however it's picking up the door because it has a solidArea thing, i dont know why.
