No idea what move_toward() does

mola

Hi@all!,

got a question about the Vector2 Method .move_toward(). What does this do? I dont have any idea.

Manual says :" Moves the vector(A) toward to(B) by the fixed delta amount." But what fixed delta ? 1/FPS? and then the amount is what? a fraction of time eg. 0,016sec?

(A) is a positionvector and (B) as well? So after 0,16 sec (A) becomes (B)? I try to figure it out and for me it seems that .move_towards is some kind of lerp?

But if so whats the full amount/100% ? 0,016sec? 1sec? 1 Frame?

Did some testing:

var v = Vector2(0,0)

print(v.move_toward(Vector2(2.0),0.5)) = (0.5,0) why?

var v = Vector2(1,0)

print(v.move_toward(Vector2(2.0),0.5)) = (1.5,0) why? v now 1,0 instead 0,0 delta remains 0.5. What does this 1.5 mean?

Thx for any help!

The "fixed delta" amount is the amount you specify as the third parameter. It should probably be renamed to avoid confusion, but I'm not sure what would be the most suitable name.

And yes, move_toward() is similar to lerp() (though it might not always be identical). The implementation differs slightly, but I don't know what's the difference exactly.
