roblox custom character collider like in unity

[next fractal]

i made a capsule, welded all parts together, added HumanoidRootPart and Humanoid
now i got one problem - after my collider interact with any stairs it starts to flip over
how can i lock whole model in place so it wont rotate in any direction

[gusty minnow]

Set the HumanoidRootPart’s Anchored property to trueto lock the entire model and prevent any rotation.

now i cant move at all
the only thing i need is to lock the rotation in any directions

but also my model should be able to move

[gusty minnow]

'insert bodygyro

[next fractal]

still does nothing
how do i set up it correctly?

[gusty minnow]

Humanoid.AutoRotate = false
put a BodyGyro inside HumanoidRootPart

[next fractal]

my model still flips over on stairs, doesnt work

also tried to change D / MaxTorque / P values, still doesnt work

[gusty minnow]

Your model flips because Roblox physics pushes on your custom collider; simply locking rotation isn’t enough. You need to combine AlignOrientation to fix rotation with VectorForce or a proper capsule part so it moves without tipping on stairs.

i dont understand how to use alignorientation in my case
should i make 3 attachments in: Head, Torso, Legs, create 2 AO’s inside of torso and connect all 3 attachments together?

Just use one AlignOrientation on the HumanoidRootPart, connected to a single anchored reference part. No need for attachments in head, torso, or legs. This locks rotation while still allowing movement.

okay, that worked
but here comes new problem: now my collider rotates to 0,0,0 coordinates, which causes it to float in horizontal position

Sounds like you just set it up wrong, and what's the collider for?

i wanna try to recreate whole destiny 2 (tiger engine) movement system from destiny 2

[lilac nexus]

Can you send a screenshot of the model in the explorer?

Also are the parts welded to each other or the HRP?

[lilac nexus]

Try doing weld constraints to the HRP

And turning off physics on things that aren't the HRP

[next fractal]

like head, torso and legs?

i should turn off their cancollide?

[next fractal]

doesnt change anything

[lilac nexus]

Not cancollied no

The physics

https://gyazo.com/7b833ba766f89ef7723d1eda950c38ea

massless

turns off physics calculations for them

actually dont do that

[next fractal]

the collider still has horizontal position ingame

[lilac nexus]

Thats what im confused about

why do you need the bodyalignment?

Cause you see that messes with the CFrame, and constantly interupting CFrames on a character causes alot of funky issues.

Is there no better way to accomplish what you are attempting?

[next fractal]

idk, thats like the first thing that limpo suggested

i dont know if there's other ways to lock the rotation for collider

[lilac nexus]

can you show me the issue?

also what's meant to be the HumanoidRootPart

[next fractal]

well basicly this is the problem ^
model should be vertical (blue is head, green is legs) but ingame whole model turns horizontal

[lilac nexus]

can you do me a favor?

can we call really quick?

[next fractal]

BodyRootPart
named it so instead of basic HRP cuz HRP has its own physics and it just wont let me to lock model's rotation
