Hey, I'm a gamedev teacher from Argentina and will definitely use this in class! (Here are my students' games.) Do you have any localization plans for this? As in, if you had a JSON file or Poedit or Translation.io project that I would happily translate into Spanish, would you consider integrating that into the build?
Great work! I would love to play even more of these. Maybe about balancing a simple cardgame, leveldesign or making a shooter feel good. A lot of your videos could be turned into something like this. With a little more polish (like better soundeffects or being able to close the game^^) you could even sell them for a few bucks and maybe get some help, so you can do this alongside your normal videos. I would buy it!
Really cool! One bug I found on windows, if you are on fullscreen and in the "playable" part, not the menu, there's no way to exit the game other than Alt+F4, at least not that I have found. Great work!
I had a lot of fun getting to directly toy with video game physics in this miniature experiment of yours. There's a lot of potential here to expand on what this demo already offers, so I have some ideas of my own to offer.
1. Give more advanced movement mechanics to work with, such as air dashes, ledge grabs, ground slides, jet boots, and more.
2. More movement presets from games that you covered before, as well as some suggestions of my own like the Fancy Pants Adventure series, Phoenotopia: Awakening, AdventNEON, and UNITRES Dreams.
3. A level editor that allows sloped and curved geometry in addition to regular flat surfaces for more level design possibilities.
4. Physics based objects like crates and ropes that the character can interact with.
5. Variable movement speed with the analog stick to allow for subtle adjustments when doing tight platforming challenges.
I'm sure that more concepts can be offered, but this is sufficient enough for me. I look forward to this neat gadget being the Mario Maker of indie games. Perhaps you can even upload it to Newgrounds if the site interests you.
I agree that these would make the toy/tool a lot better, but it does seem like he built a game engine that starts you off with a game. If that's right, then it would take a while to implement much of these.
This might be a faster way to get there: if there was a way to bridge Platformer Toolkit to Unity and show the underlying code, it would let us reverse engineer his process and add more useful features in a shorter amount of time.
This is really cool! My main complaint is that your deceleration/air brake stats seem to be the only things that have any influence on slowing down and holding the opposite direction feels like it has no effect until Kit decelerates on her own. This makes jumps using the Meatboy presets feel really weird and much less precise than they are in the actual Meatboy game.
Other than that there were a few "juice" sliders, namely the two for squash & stretch, that wished I could set to be less than 1 but still more than 0 since once they hit 1 the effect was already a little on the strong side imo. There's also a couple other aspects of the various mechanics that would have been nice to be able tweak, but at that point you'd be expanding the scope of this project and honestly those are more nitpicks than actual criticism.
That aside, it's really nice to be able to get hands on with mechanics like this without having to learn Unity, GameMaker or Godot to do it.
Fantastic idea and even better execution Mark! Hope to see more "Toolkits" like this in the future as it fits very well with your theme and is overall really fun and engaging
All the concepts at play are explained in a understandable way and operate as one may expect to see in a game engine. Great mechanical tutorial. Slowing the time scale to 0.3 creates some cool vaporwave.
There's a bug with double jump making it inconsistent and unreliable. Felt so bad that it was best to just turn it off.
One way I found to trigger this inconsistency was to jump with a single jump head first into a platform above, then land. When you next jump you can't do the seconde jump until you land gain.
Also just dropping off a ledge doesn't seem to allow the mid-air jump a double jump would normally allow.
Finally a quick suggestion, it'd be nice to be able to adjust the jump acceleration and float time in addition to the fall gravity. Default acceleration/float time felt a bit floaty for my tastes.
But overall a fun little tool to play with and get a feel for the type of platformer control I'd implement if I were to make such a game. So good job.
Nice demonstration. One thing I think was missing was the difference between "coasting" to a stop by just releasing your movement direction, and "skidding" to a stop by actively pressing the opposite direction. You can have a more naturalistic default deceleration if the player can choose to pivot on a dime if they need to, plus that animation is a great time to go hard with particle effects.
Also, when I've implemented lookahead, I've included a constant based on the direction the character is facing as well as incorporating their velocity as appears to be done here. Purely velocity-based lookahead ends up interacting with camera smoothing in a way that more-or-less cancels everything out IMO.
It's weird: when I was incrementally tweaking the controls, I had in mind an idea of a sprite with careful, Mario-like controls. But in the end I found that I'd created something in which the gameplay was a case of pressing forward and learning the jump timing, which was actually quite fun, just not in the way I thought.
I'd be super interested to be able to test this in a play area with some verticality. Apart from anything else that'd really show the difference terminal velocity would make.
While I have no plans on making a 2d platformer anytime soon, this
was still really insightful to see everything that goes into even the
littlest things like a character controller
I wonder what the speedruns will be like (sub 1 any% ?)
Really fun and informative. There's a game design (well, coding in scratch, point still stands) camp near me and I'm probably going to send them this game, it's a really useful tool for learning why a jump is more than it seems!
wdym by any%? I got a 44 second time where timing starts from clicking the start button and ends when the red flag appears, and I found this cool glitch that makes you jump really high but it's hard to execute, TAS of this game would be insane lol.
Basically: speed to max, instant movement, all sliders to max in jump and double jump. Spam P to skip all text. Also, be in the toolbox mode the entire time because it makes you invincible
Hm when I play in browser, the keyboard controls don't work at all - when I press space, the page just scrolls down. I keep clicking to get the game to take context but nope. Buttons can be clicked but keyboard buttons just don't work... is this only happening for me?
(I'm using Chrome on Windows, and I have AdblockPlus...hm maybe that's why)
(Update: Nope! Disabled Adblock and still can't use keyboard at all)
some thoughts of this game: the presets didn't fill right (e.g: celeste's down gravity is too strong) double jumps seems broken (you cannot do 2nd jump if you didn't do the 1st jump, sometimes 2nd jump just misses) if you turn on the lookahead, I think the camera's position should stay still when you don't move (instead of returning to center) You should add the offsets of the camera (because many games mainly go rightward)
And I have no idea how to implement this into a real game. I'd be appreciate if you share the source code (especially the character movement)
I seriously love how nice this is to use, an amazing idea iwth great execution. I hope to see more of this in the future, be it from you or other game designers
Somehow I've softlocked it! I was changing some controls as I fell into a spike pit, and Kit didn't die. I can't jump (I assume spikes aren't technically "ground"), so I can't get out, and there's no "reset the player character" button anywhere, so I'm stuck. Even turning on Double Jumps wouldn't get me out.
It was fun while it lasted.
Interestingly, the camera seems to think I'm grounded, but that the ground is on a nonexistent platform above me.
you highlighted the screen, the same way one can highlight text in a web page by clicking and dragging over it. I did the same thing I do that a lot, try clicking outside the game screen and it should fix that ^^ (I do that a lot tbh) You can also use the download the desktop version
idk if they can stop that from happening since its an issue with notation, bot coding, but I'd also love to see it fixxed
Pretty cool tool that I will definitely recommend to people asking me about making a platformer, but it's got a few issues.
1. The rate of deceleration when you let go of the control pad and when you press the opposite direction you're travelling are always the same. Both on the ground an in the air. This means any low acceleration setting will always feel like the player lacks control when trying to turn around; either actively trying to stop or coasting to a stop will feel wrong no matter the settings. This also means there is no way to have zero momentum decay in the air but retain the ability to turn around or stop mid-air, making Mario and Sonic like controls impossible to replicate.
2. Air Control and Air Brake are separate settings, but from a game feel perspective they are the same thing: how fast the player accelerates while in the air. This creates a weird swing in momentum when turning around mid-air if braking is slower than accelerating, which makes precision impossible. It's weird to have these separate when there is no distinction between no d-pad input and actively trying to turn around.
3. You can't make down gravity less than up gravity. I can't think of a game that does this, but we should have the option.
4. Rounded corners for collision makes the player slip off when standing on a ledge. A better solution is to slightly narrow the hitbox. Platformer player hitboxes are almost never as big as the graphic for the player.
5. This isn't really an issue one can fix, but I feel is worth mentioning. The game teaches how to tailor platformer physics to level design, when in practice it's always done the other way around. You develop satisfying physics, then design levels suited to those physics. It's out of the scope of this project, but a level editor would better replicate the real world experience of making a platformer.
6. The run & jump presets for Mario and Sonic feel way off. Probably because of issue 1. "Sonic" coming to a stop in the air is especially jarring, unless you were going for Sonic the Hedgehog 4.
Air Control and Air Brake being separate allows for things like having the air control low but the break high so you can stop in mid air but you can't just drift around.
Can you add a toggle to apply deceleration when changing directions? It feels very unintuitive that pushing left can make you slow down less than letting go of the controls entirely.

Wow, i'm impressed. This tool is amazing for learning and understanding how a game works !
Fantastic !

This was really fun! Also I felt like the UI design (including the sound design) was pretty familiar, maybe inspired by Mii Channel on the Wii?

wow love your work man
That's so cool dude. You are the best!!
Really eye-opening!

Thanks for developing this. :)
Awesome!
Thanks for great toolkit!
Hope after that practice it help our platformer feel better!
is there a place where I can learn how these mechanics are coded? like how the variables are used
Great lesson!
While I have no plans on making a 2d platformer anytime soon, this was still really insightful to see everything that goes into even the littlest things like a character controller
Awesome lesson !
this is fuuun, thanks!
Now this game gives me an idea for another game, where you *actually* have to adjust your character's stats to proceed.
Good instructional material! Thanks for sharing this, Mark!
I wonder what the speedruns will be like (sub 1 any% ?)

i want make my running curve first half as a quarter circle to make my favorite game physic, but i can't.
it like, it have a light speed to speed up, you can get faster forever but you can't reach the light speed, and slow down is normal
my english is bad, hope you get it
also, a way to build custom level for testing will be cool
idk maybe speed=sqrt(-time_key_pressed^2+some_random_constant)
i mean, i want make that things in the game lol
yeah then set your speed to that
I dont think you can make any curves in the game
That was fun! I made an interesting character and it worked, (barely) but it was fun.
On the Running page, I set the nobs to 30, 10 (or 14 for harder movement), 70, Turn Speed 99.
On the Jumping page, I set the nobs to 3.1, about 3.5 and 2 gravity, Air Acceleration 10, Air Control 20, Air Break 15, Jump Cutoff 4.
On the Camera page, I set the camera to about 8, X-axis to 1.5, Y-axis, 2, and 0.2, with Ignore jumps On.
On the Assists page, I set Coyote time to about 0.17, Jump Buffer to about 0.135, and the Terminal Velocity was 14, and the Rounded Corners was On.
On the Juice page, I set the Run to 3, Jump to 5.1, Land 40, Jump 1, Land 1.17, Trail less than 1, Angle -7, Speed 60, Landing sound effect On
With this set up, it is hard to get the last spring jump, but it is fun to try.
Another set up is the same as before except:
On the Running page, Speed 14, Turn Speed 1.
On the Jumping page, Air Acceleration 1, Air Control 8, Air Break 1, Jump Cutoff 5.
On the Assist page, Rounded Corners Off.
sounds very good. i would put the speed to 14. I think it feels better ^^
Definitely an improvement on my Platformer's Toolkit! Well done!

Would it be possible to put the source code online? Would be awesome to be able to get a look at how it's built and tweak it.
Definitely Interesting!

Amazing game, really intuitive and the UI is beautiful.
My only issue is that i can't change the settings with the controller only with the mouse.
Can you add a toggle to apply deceleration when changing directions? It feels very unintuitive that pushing left can make you slow down less than letting go of the controls entirely.
In the end, for me, it was almost identical to the Celeste one. I think it's all about control and precision in a level like this.
