Code a Platformer Game | 5. Wall Jumping Done Right!

Wall Jumping is really common in nearly every Scratch platformer, but it's not often done right! In this episode we create the classic wall sliding, and wall to wall jumping mechanics found in your favorite platformer games.

Does wall jumping feature make the slip block useless now?

[@griffpatch]

Very very good point - and no - The slip block is super important as it uses it as you slide down the wall so that you don't get caught on the little pixels that stick out. However, there is a bit of a fight going on between slope climbing, slip, and wall sliding... all three features are stepping on each other toes a little and could do with a bit of a tweak I suspect to get them to their full potential. My least favorite side-effect is that the player can get stuck climbing a 45 degree slope due to the slip kicking in when I really wish it wouldn't.

this really is feeling like a more high quality remake of that platformer tutorial on scratch you made a while ago. you did the hitboxes better, the animations better, and now the variable jump height and the wall jumps better.

Better, but a little at the expense of complexity I suppose... but it's fun to try new things :D

In the set costume script in the first if condition, you can put "wall slide > 0 and speed y < 0" to prevent the wall slide animation from playing when jumping up a wall

Love to keep up on all of your tutorials, your voice never gets boring! I love the mechanics of the game so far and I should probably add more scenes to my level :P Edit: Also, there is a bug where if you hit a small platform with at the perfect angle, it will send you flying! I'm not entirely sure what to do in this case, could you try and look at it for the video on the next episode? Thanks griffpatch!

[@griffpatch]

The problem is that the hitbox for the wall jumping / sliding is a single check... we should really change it to do two checks at head height and ankle height such that both these zones need to collide (not one or other). I might suggest this change in a video once I've played around with it. Also, we could tighten up the jump code to only jump within a certain amount of time of pressing the jump key to avoid false positive jumps...

[@legoesters]

Since tha wl jumping mechanic is from the Mario franchise hw about adding the twirl (mid-air spin): in the air, you press a certain button that will make the player spin in the air, it useful to cross huge lava pit or reach far places

[@legoboy7107]

I remember how you didn't include proper wall-jumping with wall-sliding in your original tutorial on Scratch itself, instead settling for a kind of in-between compromise between proper post-Mario 64-style wall jumping the bounding-up-a-single-wall type of wall-jumping, so this is nice to see! The other system was fine on it's own, especially if you tweak the physics to be snappier, but adding sliding is definitely preferred.

[@autisticChronicles360]

I plan to make my own platformer with 2 characters, which can by swapped via swap points. Each character will have their own set of unique abilities (specifically one being able to wall jump, and the other being able to shrink in size in order to fit through small pathways). I am a Scratcher with the username of Crosbyman64, and a 5 year Hopscotcher (it’s an iOS app that is also block based coding similar to scratch, but more limited) with the same username. I already came up with over 40 different tiles that all behave differently. All that’s left is to design each tile, add specific collisions for those tiles, add functions from interacting with certain tiles (because one tile is a button (which can be activated by standing on it, or by moving crates onto it, but it will release when nothing is on it), and another tile is a jammed button (which can only be activated by a ground slam, but unlike the normal button, jammed buttons will be stuck in place after activation)), make use of reusing clones (like the tile scrolling from your Mario series), and generate levels based on a level string (xxyy{tile_ID}, i.e., 0405A). If you are interested to know, the two characters are named “Shaperson Square” and “Starlynn”. They are quite literally what their name says. Shaperson: Can wall jump (due to its surface area) Can Ground Slam (whilst in mid-air) Starlynn: Can double jump (not normal for most platformers, I know) Can Shrink in size to fit through small pathways Can jump on sticky tar (yet another tile I came up with) All tiles: 1. Grass Tile 2. Dirt Tile 3. Stone Tile 4. Weak Platform (could collapse from standing on it) 5. Bounce Pad (similar to Trampoline from your APPEL game) 6. Button 7. Jammed Button 8. Key 9. Door (unlocked by key) 10. Reinforced Door (unlocked by button) 11. ON/OFF Switch (switches tangibilities of switch platforms) 12. Red Switch Platform 13. Blue Switch Platform 14. Sticky Tar (slows movement and prevents Shaperson from jumping) 15. Pink Alternating Platform 16. Blue Alternating Platform 17. Anti Gravity Platform 18. Ice Block 19. Breakable Platform 20. Collectibles 21. Collectibles that follow moving tiles 22. Checkpoint 23. Golden Star (like the red apple from APPEL) 24. Goal 25. Spikes 26. Saw 27. Hydraulic Press 28. Lava 29. Crate (can only be moved by Shaperson) 30. Swap Point 31. Small Pathway 32. Geyser 33. Laser Beam 34. Danger Light Tile (white, yellow, red) 35. Portal (8 different colors, teleports player to portal with the same color) 36. Wall Jump Platform (only Shaperson can wall jump off this platform) 37. Hidden Pathway 38. Hidden Collectible 39. Trigger Tile 40. Lock Camera 41. Boundary Tile 42. Spawn Point 43. Hints Some of these tiles were inspired by your APPEL game.

[@jimmyindradi2960]

This was really helpful!

[@noc5]

Just a quick tip for you guys. If you want to make the walljumps mega man x style, where you can still scale a wall without any pushback as well as being launched off if you go in the opposite direction, just find the long jump change and make it 0 - the abs of longjump. You won't get any pushback, but if you don't try to jump back onto the wall, you'll still be pushed off

[@QuantumScratcher]

You can use a variable called 'wall jump length' or something similar to store the length of the long jump instead of hard-coding it. (You could do (direction / 90) * wall jump length instead of (direction / 90) * 7)
