The default target move speed pattern of Move effect is something like
Beginning with a very slow target move speed, gradually increasing to the highest speed at middle of the move, then gradually reducing the speed to zero at the end.
Is there a way to make the target moving uniformly with just one constent speed from beginning to end?
The default easing that you describe is using the Sine easer.
You can give the effect a Linear easer to get the behavior you are looking for.
