I loved how simple this was - I didn't need a full-blown inventory. Well explained!

[@skalk6137]

Its a great tutorial but I feel like you did not do such a great job explaining what everything does so, I feel like I did not learn that much, but it worked so that's good enough. Thanks.

[@TabbedOutRat]

Great tutorial. Please note the link to the website doesn't work in the description.

[@user-eh3ru3yv1o]

thank you

[@digitalswordplay]

Great job! - Any chance you could expand and add stacking, sorting and equipping in future videos ?

[@yalikeren]

great tutorial! (btw, title says "Simply" and i think it it was meant to be "Simple"?)

[@GameMakerCasts]

Yup! Lol.. thanks. All fixed

[@specterrev]

i have no clue if you still check the comments but, when writing the add function the "if(array_length(_inventory) < _max_inventory_items)" gives me a error saying "the type 'undefined' appears where the type 'Array' is expected."

[@GameMakerCasts]

double check your variable _inventory then. Array length expects that variable to be an array. That's what the error means.

[@specterrev]

@@GameMakerCasts the variable was written out the same exact way it was in the vid and no matter what I did the error didn't go away, I just reopened the project because I saw you replied and the errors randomly stopped, regardless thanks for taking the time to reply

Hello, i have issue - when i hit "I" nothing show up. Instead my computer starting crazy and i have to close it with Ctrl+alt+del. Is there any changes? Any ideas? Thanks!

[@Gladiator373]

i figure out - i had wrong { } -
But new one rise up - my columes re not clicked when i hit them. Istead of that when i hit somewhere in "space" my columes are hit. Seems like big range of that or smt

[@GameMakerCasts]

Hit me up on discord and i can help you through it discord.gg/jwaCrcSZ

[@mancakw8308]

when i tried pressing "i" the inventory did not show up, do you have any idea where i get it wrong? (sorry for my bad english)

[@GameMakerCasts]

To me that means the step event isn't right. Should have something like if(keyboard_check_pressed(ord("I")) { .. }

[@georgehennen]

Are you, by chance, looking for someone to make more tutorials? I feel like I have so many years but want to make tutorials for stuff. I have made games before, even on steam. I ask because I notice it's "casts" not just one guy.

[@GameMakerCasts]

Messaged you through X.. errmmm Twitter

[@michaelhooper1474]
