Hi all,
Pls could someone help me to figure out how to limit movement of camera by some geometry (for example box)
Here the sample of camera behavior that I want to create

thanks all for attnetion,
Kind reegards.
Hi
To do that, you can enable collision for your camera and your box.
Read the doc : Cameras, Mesh Collisions and Gravity - Babylon.js Documentation
Hi Ivan! Here’s a better/fresher demo (and thx for the broken link report):
https://www.babylonjs-playground.com/#19LV1D#1
Only for free-cams, of course. This built-into-BJS collision system is designed-for camera-to-object free-cam FPS-shooter games, and similar uses.
The camera.ellipsoid collider can be set to any dimensions, and there is also a camera.ellipsoidOffset which “shifts” the position of the camera’s ellipsoid collider, if wanted.
There is also a static property… engine.CollisionsEpsilon (BABYLON.Engine.CollisionsEpsilon) that affects the “scrub-off” and “climb-over” angles/characteristics. We can talk more about scrub-off and climb-over stuff, later, if ya want.
Generally, avoid colliding with low-height obstacles, for now. Or maybe use obstacle.ellipsoidOffset.y to raise the collision ellipsoid on low-height obstacles.
What happens: camera tries to climb-over low-height obstacles (dependent upon engine.CollisionsEpsilon setting)… but camera keeps being pulled back to floor… due to gravity. This makes freecam “jitter” when continued up-arrow PUSHING the camera… against a low-height obstacle.
I hope this helps. Got questions? Just holler.
Yep, it works, now I need to insert geometry that I created in some 3D program, and I need this geometry to limit the camera, do you have some similar samples?
To import geometry I encourage you to use Exporters from blender, 3dsmax or Maya or anything capable of generating .gltf file format:
https://doc.babylonjs.com/how_to/load_from_any_file_type
Then you can easily flag any mesh as collidable like in @Wingnut sample
Funny situation, when Im importing mesh to scene, it doesn`t limit my camera and this camera falling down…
Did you make sure to flag them as checkCollisions = true;
And beware: make sure to flag the right mesh (as you may have a hierarchy of meshes)
Hi,
I have box check collisions,
Maybe I need to write mesh.checkCollisions=true ???
Well with just a screenshot it is like trying with a crystal ball:)
Can you repro in the playground?
I hope it will be better
and that does not work? So weird. Please create a repro in the playground
It works, for box it works, but for mesh not, and I`m trying to figure out how to do that,
And sorry: what does it mean “repro in the playground”?
try to recreate the issue here: https://www.babylonjs-playground.com/
A doc about how to reference external assets: Babylon.js Documentation
I inserted my code, and saved by the name of current topic, is it enough for you?
nope:) I do need it in the playground to be able to easily modify it

I hope thats it…
This seems to work? What is not working on this playground?
