Look_at and rotation

MMagicLord · Mar 28, 2018

Hi there,

I have this code, a rotation is applied and the object continue rotating as i keep pressing a key. rotation = oldRotation

Adding look_at, the objects look at the vector. But the next line of code changing rotation is no more applied the same way , the objects only rotates 10° if i keep pressing a key, when i release the key , the rotation is reset.

look_at(transform.basis.z, normalMedium) rotation = oldRotation

Does look_at is a function that is called after all other spatial functions are called , so it overrides any next functions calls ? It's really strange.

I think look_at rotates as soon as you call it (or at least, it has for me with my IK plugin). Can you post some example/sample code for debugging?

You can download the project from github https://github.com/DevMagicLord/Godot3/tree/master/debug/racing

There is lot not needed code from another project i modified, look inside the function func race(delta):

What i try to achieve is an arcade bike gameplay. It needs to align to floor normal and follow Y rotation the player inputs. I done that in the past and followed some tutorials, it should be easy but i'm missing something in Godot.

Cool, I’ll look at this soon!

Well, I've look at it and despite my best efforts, I cannot get it working either. look_at is giving strange results, at least not the results I was expecting.

I'll look at this some more later!

I was trying look_at for something in another project and i also got very strange results with position and scale change. There must be some bug with that function, i avoid it and use simple math instead until we got a function like align_to instead.

Yeah, that's probably best for now. Hopefully things will be fixed in the future.
