Sprite Sheet Animation problem
« on: August 16, 2011, 03:56:02 am »
I am trying to get a spritesheet animation for walking a player..
Basically what I did is get an IntRect withing a sprite image and move the IntRect to the next frame of sprite along with the actual movement of sprite on the screen.. but now the animation plays really fast.. how can i slow down the animation.
Here is what i did:

if(RIGHT key is pressed)
{
  move the IntRect to the next frame;
  move the sprite;
}

You need to watch how much time has passed and only advance frames accordingly.  Something like this:

Code: [Select]

void Animation::Update(int ms)
{
  // this function would be called every update (every "frame")
  //  ms is the number of milliseconds passed since the last
  //  frame
  time_remaining -= ms;  // subtract the time passed from the
         // time remaining in the frame

  // then keep advancing frames until time remaining is above zero
  while(time_remaining < 0)
  {
    AdvanceToNextFrame();
    time_remaining += ms_per_frame;
  }
}
