So I was playing around in XNA earlier, and I felt like the movement of the sprite was really choppy. So I tried to set up a sort of smoothing code

Code: Select all

 private void UpdateInput()
        {
            KeyboardState newState = Keyboard.GetState();
            
            if (newState.IsKeyDown(Keys.Space))
            {
                for (int i = 0; i > 10; i++)
                {
                    PlayerXY.X += i;
                    UpdateLoc();
                }
                
                
                if (!oldState.IsKeyDown(Keys.Space))
                {
                    
                }
            }
            else if (oldState.IsKeyDown(Keys.Space))
            {
                
                for (int o = 10; o < -1; o--)
                {
                    PlayerXY.X += o;
                    UpdateLoc();
                }
            }

           
            oldState = newState;
            
            
        }
        private void UpdateLoc()
        {
            position = new Vector2(PlayerXY.X, PlayerXY.Y);
        }

And its setup in a gameloop that looks Like

Code: Select all

UpdateInput();
UpdateLoc();

It worked perfect when I just had the PlayerXY.X +=50; instead of the For loop. However when I use the for loop nothing happens when I press the space key.

Think you guys know whats wrong? Thanks!

Did you update the Draw() method? If so, does Player get the new Postion Vector2 passed trough?

The UpdateLoc() method you see in there calls a method I wrote that updatesit for me.

Are you using a velocity system? If not, the movement will be terrible because of the keyboard buffer.

Yeah, that was the point of the for loops, was to make a velocity system. So everytime it iterated through the loop it gained +1 speed till the speed capped out at 5. Then when you let go it would go through a loop that would -1 speed everytime it iterated till the speed equaled 0.
