simple Question about movement
hi,
i'am fail on a simple question (shame on me)
i have an object with a position of
0.0, 7.49, 1.8
i like to move this object over a time (2 seconds) to the new position
0.0, 48.0, 71.0
first i get the directionvector an normalize this
my animatefunction looks like this
anyone can helps me ??
thanks

Code:
(float)update :(float)timeElapsed
{
move the object with the normalized vector but how fast ???
}
anyone can helps me ??
thanks
On the y axis you want to travel 487.49 in 2 seconds, so the speed on the y axis is (487.49)/2.
So to update the y position:
y+=(487.49)/2* timeElapsed
Same for x and z.
You can also do it with the normalized vector but you end up doing more calculations than you need

You would like to move from A to B in t where t ranged from 0 to 2.
let u = t/2, so now u ranged from 0 to 1.
P(t) will be a function which gives you the position at time t,
You start at A, and away from A toward B, so:
P(t) = A + (BA)*u
P(t) = A + (BA)*(t/2)
So for example,
P(t).x = A.x + (B.x  A.x)*(t/2)
let u = t/2, so now u ranged from 0 to 1.

Sir, e^iÏ€ + 1 = 0, hence God exists; reply!
thanks, that works :)
