IMPORTANT!!! On coding the Animations - Stand pose on Slopes/flat tiles On it you should Copy and Paste/ Replicate the exact order as in the video Stand Hitbox 0-4 Should be After the Standing poses Replicate everything in order as it is n the video ( 14:21 ) From Sprite 1 to the final number ( depending how much you have done sprites for more customization Reason being? You Could get in trouble with *wrong poses* while *standing* i got this issue tried to replicate the same code again checking that everything was same the problem was that the Stand Hitboxes were in the wrong order and the Pose sprites too to counter this Make sure to have it in the dedicated order as in the video or you May find some trouble i even added Blank sprites for wall slide/wall pose Stay scratching everyone ;)

[@Taelo]

Hey Griffpatch, another great video! I know you've already got lots of projects on the go but would you ever consider trying to make a mystery dungeon game?

[@Taelo]

I just thought it might be interesting since it would combine a bunch of different projects you've already covered. It would be tile based with randomly generated mazes and enemy pathfinding. The new stuff you'd need to cover is making the player and enemies snap to the tile grid, have the enemies only move when the player does, and then the turn based combat. I know this would get really complicated quickly so I understand if you don't have time for something like this but I thought I'd ask anyways.

I have a quick question for another episode, could you make a tutorial on how to make a sort of waiting stance like Sonic, kind of how if you leave him standing there for a few seconds, it plays an animation? I think it would really look good for Scratchy. Edit: Also maybe jump sound or just a full-on sfx tutorial, because no matter what I try, the sfx for my jump never plays.

[@kierdalemodels]

Yes, a way to put in an ‘idling’ animation would be cool.

[@CrabO2]

maybe you found your answer, but: if not walking/jumping/etc: variable + 1 every idk 0,01 second if variable = (your number): play your animation and your need to set this variable to 0 every time player doing something (its pretty simple tutorial, improve it for good results)

If this video wasn’t here, I wouldn’t have made any progress in my coding ever! Edit: I have a question, since I’m making my project, Im not using your scratch cat costume, but I use a pixel character that doesn’t have a slope sliding costume, what should I do to make it look like that it is sliding down? (I searched the character on the internet) I hope you could answer my question, it would be very helpful to me! Thanks again!

Hey there, you can either not worry about the costume changing, leave it as the normal standing costume, or you need to try to do some clever drawing to fit the costumes! I'd probably just not worry about it. Most games don't...
