General / Smooth rotation of a sprite

« on: November 30, 2018, 11:51:06 am »

Let's say that I have a sprite and with code shown below I obtained a rotation angle:

rotation = (atan2f(dy, dx)) * 180 / 3.14159265;

How do I rotate a sprite smoothly with angle I have in "rotation"? I tried something like this but it didn't work:

for (int i = 0; i < rotation + 180; i++)
   sprite.setRotation(i);

Move your sprite from A to B, and then from B to C.

I'd do it by adding a variable "last point reached", with the index in the vector of the point you started at (e.g. you start at A (0), go to B(1), then C(2)...)

The problem is that in "while loop" sprite instantly moves from one point to another. I want it to move smoothly to the next point.

Let's say that I have current and next coordinations of a sprite. How do I rotate sprite towards the position of the next coordinations?

I have a vector that contains points. I already can move sprite from point A to point B, but I don't know how to move sprite from point A to point B, then to point C and so on. How to move sprite by multiple points that my vector have?
