is_on_floor not working in Godot 4.1.2 (Latest version)

udeveloping

Hello community! I'm newbie in Godot Engine, i was unity user and currently GameMaker Studio dev, but i have seen many cool features inGodot that i can implement for my game, so i decided to make this trip!

I was watching some tutorials but they are in godot 3.5.3, for 2D platformers in this version they use KinematicBody2D but in new version there is CharacterBody2D, when i attache a script for it, i got a basic code for moves, but when i run the game, everything goes cool but is_on_floor is returning false forever, no matter what! I decided to check grounds using 2DRays and now its fine but i would like to know, why is this not working anymore? I'm afraid that is_on_wall and is_on_ceiling will neither work!

Is this a bug of this version?

PD: i used the classic exmaple for move_and_slide but in Godot 4 there's no parameter for this function anymore

udeveloping Make sure that character body's motion_mode property is set to grounded.

udeveloping

xyz indeed! it is! that's the default value!

xyz

udeveloping Check if collision layers and masks are properly set up. Other than that hard to say without seeing the scene and code. Can you make a minimal project that reproduces the problem and upload it?

Hello back! let me give more context. These are the image showing all setting info you need, i am almost sure that is a Godot 4 bug!

This is my Player (Character Body2D settings)

This is my CollisionShape2D

The Player Scene structure

The World Structure and Tilemap settings

Regards!

udeveloping Better to make a minimal project. It's hard to debug from screenshots.

xyz Indeed! it is a minimal project, i am just starting to use Godot so i am not doing a great thing:

1- i created a scene for my player (screenshot) i added a script, and a script came by default with basic inputs (horizontal moves and jump scripts)

2-i created a world with tilemap and i added the physics and colissions rectangles to tilemap tiles aswell

3- i added the player to the scene, pressed F6 (run current scene)

Then i noticed after printing a debug message into is_on_floor condition that, is always returning false! I made different tests using differens snaps and safe_margin but nothing changed!

I implemented the classic 2Dray for casting when i am on the ground!

PD: i m doing right now the same in godot 3.5 to check differences!

I have replicated the last example on Godot 3.5.3 and move_and_slide worked perfectly, is_on_floor function is 100% working fine!

Conclusion: is_on_floor in Godot 4 is bugged!

Not necessarily. More likely there's an oversight in your setup or code. Replicate it in a blank 4.x project and post the project. Someone will take a look.

xyz ok letme do it and post it! Let's figure out what´s going on into Godot 4

udeveloping

First i made and never is_on_floor worked!

I don't know what's happening! I would like to know what i did wrong in first project!

Regards!!!

udeveloping The up vector for your character body is properly set to (0, -1) in the player scene. However in its instance placed into the world it is overridden with (0, 1). Now the up vector points down so is_on_floor() registers ceiling collisions instead of floor collisions.

udeveloping

xyz hollymolly! How's that possible? I didn't remember do such a thing xD

udeveloping Someone must have been messing with your project when you weren't looking 😃
