[OUTDATED!] How To Make An Undertale Fangame (Game Maker Studio 2)

Extremely underrated video. You did a great job on editing and actually DOING the whole thing. I wish you millions of views on this video, I think you deserve it.

Hey @RealSilGaming!
You can't imagine how thankful I am for this tutorial/project. Me and a friend have been wanting to make a fangame for a long time, but we just couldn't get the textboxes and battlesystem to work well.
I'm currently trying to re-write the game and base it off of your project, as it works just so extremely well. I'll be re-arranging the file structure and re-naming the variables and files, as we prefer a different format. I hope that sits well with you, and I will of course be mentioning you in the credits for this huge help.
Once again, thank you so much!

Hey! This tutorial has been amazing! However, I cannot seem to get the alarm script to summon bullets for me, (9:17). My code is written the same as in the video (aside from obj_bullet being obj_swordbullet) and is on the obj_globalparans object and in the Alarm 0 script. Is there any reason as to why it isn't working?

[AadiatAhmed]

not only Undertale, but literally then entire gamemaker is covered here

[le_smiley_sky]

I just finished the tutorial and it works perfectly, i have to say... Thank You !!! It is nearly impossible to find a complete series of tutorial to learn how to make an undertale fangame and this video is a masterpiece !

[DaniAoikitsune]

25:33 the buttons are not appearing I've checked over it many times I'm not sure what I missed

[le_smiley_sky]

This is the best tutorial i have ever seen ! Thank you, thanks to you I will be able to start programming my fangame ! ^^

AMAZING video, very informative and very well edited.

[Akanalusa]

It's amazing to see how much work is put into these games.

[Riddleoftheroccs]

If anyone is having trouble getting the white box to show up, make a create event for the BulletBoard with "current_width = 0;
current_height = 0;" in it

[agg]

at 8:00 i think when i play it the attack only deals dmg onces and then make the soul blink for ifn how can i fix this

[pepsicola]

1:44 what is in the create event for the bulletboard?

[Ghajlalalala]

Thank you. this is super helpful for even a game not like undertale, which still follows a bullet hell battle mechanic.

[AngelEquals]

At around 1:31 you changed to obj bullet board, from obj params, and then i just got lost cause coding.

[shapeposts]

This is my first ime using game maker it might be complicated but definitely worth it

[matthewthepro]

Ok for some reason despite putting the globalparams into the rooms and making it the parent of bullet boarf just incase.
Also doing everything correctly.
The white box wont appear
Pls help.

Was I supposed to make objects and sprites for all the menu buttons BEFORE coding them to have a function?

[goldenfreddy_]

I did everything correctly for the Bullet box, but for some reason when I clicked the button to run the game, it only shows the soul and not the box- I’m really frustrated because I wanted this to work, any idea on why the box isn’t showing up?

[therealhfk]

I am having trouble with using surfaces. Whenever i try to draw an object on a surface inside the bulletboard, it only draws itself on the outside, but when it goes inside it just disappears. I am not very experienced with using surfaces so i apologize if im just being dumb, i hope you can help me
