we may want to make the separate camera from platform function a behavior by making it check for collision of an object groups assigned via a behavior for the obstacle

edit:
I don't think this is really possible without js at least, I cant find anyway to use a object that has a certain behavior, i did find another problem though, if I put an obsticle above the player, that it doesn't collide with it, and when the player is inside it moves the player outside of the object on the x and y axis also collisions with slanted objects (image attached) are wonky

Yes, I wasn't sure if this was useful or not, but it should be easy to fix.

It's not ideal but expected.

There won't be one good and easy to implement collision method. I want people to be able to use there own collision method for instance a floor following with a raycast.

gravity value and jump height are broken, solution, add platformer trajectory extension (seems like you used a function from platformer trajectory without the extension being installed, either add it as a dependency and into the example or take the function from the platformer trajectory extension and put it into the jump 3D extension to prevent the need of installing more than needed
suggestion, make max falling speed the same value as gravity and replace it will jump speed (how fast the player goes up when jumping, seems like the property is there but there is no functionality)
rename land on floor function to cancel jump, and make desc something like "Cancel the jump of object causing it to fall"
when on floor, the is on floor value fluctuates from true and false

why is this a problem? if someone wants to say create a object when on the floor than they would use this event and a trigger once so it wouldnt keep doing it every tick/frame, the problem is, even if trigger once is on, it is constantly fluctuating, so it would just keep spamming objects if that makes sense

Thanks a lot for your feedback. I fixed the issues and added an action to abort the jump.

awesome, can you send another copy of the example so I can test the updated version?

[gabrielzv1233]

nevermind, figured out that the link updated automatically when you put a new commit in, I do see that the problem with the fluctuating is on floor value is still there and wasn't mentioned to be fixed in the commits, if you want to know how I see if its still fluctuating, I just use this code and a lazaly slapped on textbox to the scene

works well, and shouldn't need to be more accurate, if its not a solid true when on the ground than its still brokey :\

Do you see anything else?

Thank you for your feedback, I'm moving ahead with this.
Please open an issue if you want to talk future improvements.
