I made realistic creepy legs with IK | Scratch Devlog #1

A griffpatch Scratch Game Devlog - "Spooder Cat". Creating 8 intelligent legs that using Inverse Kinematics can bend, walk, climb and navigate an arbitrary level is the goal of this episode. It's amazing what we can make if we set our minds to it, so enjoy the fun following the progress of this experimental Scratch Project as it is coded. Nothing is set in stone because the project has only just begun - This is your chance to make a difference and take part in shaping a work in progress :D - The final project will be shared on Scratch!
My tutorials are for all budding game & software developers using Code Blocks. Scratch On guys!

Hello Fellow Scratchers - What do you think of this project so far? - Please LIKE 👍the video if you want to see more, and DO COMMENT and share your ideas about what this game could be! I'm excited to share the best ideas in my videos and hopefully they will make their way into the final game released on Scratch - Woohoo!

Hi griffpatch i love your tutorials

[@ZainTheMan]

Veery cool and cute

[@coder1233]

Love your voice and videos

[@pietrosmusi6348]

You should make a game where you're a spider hidden in a wall and you need to move around to avoid pesticides

[@Wall_nut77]

Spooder cat lol

[@crackerpooppop]

A possible game idea is you have to get through scrolling levels such as houses or forests playing as the spider, avoiding things like larger animals & vacuums, and there's safe places under furniture and in cobwebs. It could also collect stuff like flies

[@griffpatch]

ha vacuums - I like that one especially

[@alloftheabove123productions]

This is crazy! How easy you make Inverse Kinematics look I love these kind of Devlog Videos, keep them going! Also, that would be a truely awesome collab, and I think the whole Scratch community would benefit from it.

[@albator8159]

This is a really cool concept ! sometimes I like to get ideas from your scratch projects and make it with other programming languages. Please keep going with this one !

[@trentenroberts2748]

Rainworld uses a technique where the gravity that's affecting the body gets reduced for every limb holding onto a wall. I think this would be an awesome technique for this, as your spider would struggle to hold themselves up with just 1 leg

[@marioman98]

lol I had that idea when i made mine without knowing any other games did that.

[@Fail-harold]

Thats actually pretty smart, i never thought about how rain world handles that

I love how you go more into the theory behind the code rather than the blocks themself, this makes these videos not only interesting/useful for people using Scratch but for basically any programmers

[@thetechpanda6151]

I really can’t wait for this! You could code a game that scrolls upwards and there are blocks you have to climb through or dodge and the higher u climb the more points u get but there is a timer and u have to get as many points as possible during the limit

[@griffpatch]

Cool idea!

[@Richard_Nixon-mr6rq]

Hmm

[@Darkstar327]

[@corbin4360]

I love this style of video. I usually don't actually follow the tutorial videos, I just watch them because im curious how you implement various mechanics. So this type of video is perfect!

[@lasercatto]

I moved on a while back to more complex coding languages, but it's really interesting to see what you're cooking up in Scratch, and teaching to us all - keep up the good work! I'd like to see a video on the process you go through while you make a game, especially brainstorming ideas and trying them out, and how you do so. - subscriber since 21k subs

[@HereticWitch]

griffpatch doesnt always come up with this stuff what i think is truly impressive is how he was able to translate things from wikipedia it into sratch code, i tried doing inverse kinematics more than a year ago and failed miserably. The only time i could succesfully do something like that was making an isometric tile engine

This certainly does have huge potential! I think there could be different levels you have to play through, moving around just like you do here, with (sometimes deadly) obstacles and stuff!

[@Tnac9]

Great way to start my morning. Haven't seen a devlog in a good while!

"It's just some simple trigonometry" - Griffpatch This is really cool! Excited to see how this series will progress

[@SombreroMan716]

Heh, I mean… it IS really just simple trig tho…

[@jmejuniper]

I mean, it is. You should see advanced trig 0-0. Honestly though, trigonometry in schools is made to be much harder than it is with stuff like sohcahtoa. Understanding it as right triangles on a unit circle makes it so much easier to know *when* to use trig.

[@hheroiscool]

Holy crap, a collab with Griffpatch and CrystalKeeper? Cant wait to watch next vid!

[@wavaction8862]

I got an idea for the game! Basically, it will be a sort of scrolling game where you need to climb around, there will be 3 types of dangerous obstacles : The leg killable : It can destroys the player if the legs touch it, however the body is safe. Body Killable : Same thing as the leg killable but now the body isn't safe but the legs can still touch it. The killable : It destroys anything it touches. The goal is to maybe catch keys (which will put in use the leg killable and the body killable to like be strategic how to get a dangerously placed key) and the keys will help to open a door to go in next level. Also try to add bosses, you make amazing ones! (Sorry for bad grammar, english is not my primary language. Also keep up the good work griffpatch!)

[@Skraftzz]

I literally did something similar to this for my Computer Science Final Project in scratch. Which I had this back then.

[@noot_noot843]

I love the vids! Can't wait for #2! But i have a question about the extension you are using, and how do you make it so that you can search for blocks and then even search for what the inputs should be? like at 5:02 you searched for (90-(ang)) but im using scratch addons and i can only search for blocks like (-) or (ang)

[@Wungle_bungle123]

What I think would be AMAZING would be to have ur game turn into a puzzle adventure game. To simplify my idea, you could have spider cat navigating a room filled with obstacles and enemies. Then the player would need to collect items (say a key) to complete the puzzle. Once said puzzle is complete, a door would open and lead to the next level. I first discovered you from papercraft on scratch and I love your content!

[@ghastdude589]

Totally not designing one right now where you hide from a giant spider in a cave system (waiting on devlog #2 for the better leg movement!)

[@aa_1330]

Wow, this is awesome! I don't know how you managed to figure out that the leg parts joined at one end!

[@Void1734]

Nice! For some reason, I had this idea where if the spider goes too far away from a platform and all the legs detach from the platform, if they're no other platforms for the spider to grab onto, they would just fall to the ground. I even applied the physics in the project and all that's left is collisions and smooth leg movement. This makes me excited for the 2nd devlog!

[@ChickPartyYT]

I always waiting for more videos of griffpatch!

[@mohammedabdulraheem628]

Can't wait for the release of the game and can't wait for part 2 and the collab !!!

[@TheMonkeDuo]

My version

[@paths7969]

i never thought ik in scratch would be so easy, at least you make it look easy. this def feels like the perfect movement for a puzzle game (i just finished playing the portal games) perhaps a tower defense ish game where you have to make a web with obstacles? im not sure but anything you come up with will likely blow me away XD

[@CrystalKeeper7]

[@inkerbell5456]

Coding this up was really fun... I cant wait for a part 2! :~)

[@blueboytube]

So I don’t know how ambitious you want to go with this project but seeing the game art example kind of reminded me of Ori (somehow even though the styles don’t look that much alike) and I thought the escape sequences where you dodge some giant creature are always really fun so that kind of gameplay with the artstyle of the shown example would be quite a big deal but an insanely nice project

[@slavdecepticon]

Recreated this just by looking at the code! Very fun to play around with!

[@dimostuff535]

I love this tutorial!

[@NateFigetProductions]

I have a nice idea! Basically, your cat has to go around the map searching for ants, which does run away. When you catch the ant, you eat it, making your legs grow longer for more range. As you grow bigger the map also grows bigger, and as the map grows, the more ants there are. And thats my idea for this.

[@GunkleSeven]

Having the legs propel the player if they want when touching a surface would feel and look awesome!

(Also a very nice addition to my idea is so that it can be multiplayer and the bigger players can eat the little players!)

[@captainsprinkles6557]

I think a cool idea is you're in a house(or anywhere really), and the main goal of the game is to make a web, hunt prey down, take them back to your web, or set up traps. Could be a survival game with interesting mechanics, or a horror game where *you're* the terrifying spider monster.

[@killianpgt]

It's amazing to make a complicated thing simple with simple calculations

[@Tedification]

This looks great! In real life, I think spiders can make sticky or non-sticky strings of webs. what about a sort of puzzle game where you have to shoot webs to walk on and/or go through to get to the flies or avoid the wasps? (where you can only walk on the non sticky webs, but you can build more webs on either types, and you catch flies only on the sticky ones.) I am also very exited by the idea of a collab with CrystalKeeper7, and am thinking of a vibe akin to Rainworld. Perhaps there would be a large scrolling map that you have to get around that is filled with many creatures and bugs, (some friendly, some enemies and some food) but you can't see very far. Instead, you must rely on the subtle movements of the webs made my other creatures (detectable by the web's coloring). (eg. if there is an enemy to the right, then the webs to the right of your spider will quiver red, but if it's food, they'll quiver blue.) I have so many ideas, I might make my own game! XD

[@Tedification]

also, Rainworld has a really cool AI ecosystem that I would LOVE to know how to do!
