Controlling arc axis with Vector3.Slerp

I'm using Vector3.Lerp() to instantiate some prefabs at a set distance from each other. This works, but I've just started playing with Vector3.Slerp. This creates a nice arc, however I'd like the arc to happen on either the X or Z axis, not the Y. …

Lerp with Time.deltaTime

I have a question about Lerp. So I know that lerp helps you to move your object like: void update(){ transform.position = vector3.lerp(start.position,end.position, (Time.time / 1000)); } this will get your object to your endposition. But if you…

How can I transform 3 objects to swap positions, but make sure they aren't moving to a position an object is already going to?

I have applied a code to 3 objects. So far this code switches three cups around so that they swap places. The code gets the start position of the cup, and then the end position of each cup. All 3 end positions are actually the start positions of the…

Why is a lerp function written like this: (1 - bias) * start + bias * end;

I've seen a couple of lerp functions, mainly for lerping vectors, and they seem to go like this: vector lerp(float bias, vector start, vector end) { return (1-bias) * start + bias * end; } Whereas my naive way of doing it would be: vector…
