Godot 4 Sourcelike Ladder Movement Tutorial | Intuitive Movement & Ladder Boost

The eighth video of a series where we will build an FPS game. This video shows how to implement sourcelike ladder movement, which takes into account both the player's look direction and directional input to control how they move up and down or side to side on ladders.

*NOTE/CORRECTION:* I just realized line 216 is not necessary as it's referencing (local) basis vectors for both camera and ladder. You don't need this and it will work fine, so I recommend taking it out. In fact it may bug out if your Camera3D setup is slightly different than mine. Here you can see I simplified to just dot product of 45 degrees from up with forward move: github.com/majikayogames/SimpleFPSController/commit/d6a00968cc56cb02923a4986cb1374bd162e594b

Thank you so much for these tutorials. No one else is covering these topics, especially stair stepping. You are creating tremendous value for the Godot community!

[@MajikayoGames]

Appreciate your comment :D I plan to add a bunch more to this series. Also working on an update to my free SimpleDungeons addon so I hope I can continue providing value to people!

A small improvement would be using a signal, either on the ladder or on the character, to inform the character to start climbing to avoid checking every ladder in the whole scene. Doing it this way bypasses the broad phase so it could get laggy if there are a lot of ladders. Cheers, great series

[@MajikayoGames]

thank you. yes it might be a little faster if using signals, however the Area3D is only updated as to whether its overlapping once per frame anyway, so we still check however many ladders each frame but i thought it should be negligible as it's not actually a physics check i dont think docs.godotengine.org/en/stable/classes/class_area3d.html#class-area3d-method-overlaps-body

Awesome bro 👏, this tutorial keeps getting better and better, I really hope you’re planning on adding arms, weapons, shooting and stuff like that

[@MajikayoGames]

Yep, going to work on my SimpleDungeons addon for a bit, but after that one of the next things will be weapons & character model. Glad you enjoyed! :)

@@MajikayoGames Perfect 👍

Please show us how to make a hook / Grappling gun🤔

[@collinvisser7108]

Neat - thx

[@ItsKorin__]

for me the jump velocity multiplier was a bit to hight but 0.5 did the job

[@MajikayoGames]

glad it worked for you :D thanks for the comment. yeah it depends on how you want your game to feel.

@@MajikayoGames thank's, amazing tutorial series by the way

[@debiprasad3946]

Please make a video on player and vehicle interaction

[@MajikayoGames]

Will add this to my list of ideas :) I still have a bunch of tutorials to get through for this series I have planned. Next is going to be a weapon manager, HUD, and character model.

You need to teach us how to replicate the source surfing.

[@MajikayoGames]

I already did a video covering this :) kzbin.info/aero/PLbuK0gG93AsHID1DDD1nt4YHcdOmJvWW1 This is the 8th video. The 1st of the playlist covers surf & bhop.
