I have a ghost that moves in big increments of 2 pixels
Example:
If ghost moves in position x: You see the x coordinates of ghost like this: 18, 20, 22
Ghost causes no slowdown when drawing it.
However I have an alien that moves smaller increments of .05 pixels - .15 pixels
Example:
If alien moves in position x: You see the x coordinates of alien like this: around 30 drawings in 13.34 which is 30 drawings in the same spot of the screen. Then increment the position by .15 pixels and redraw the alien in that same spot.
The idea was to make the alien moves so slow with the alien theme music to add character to the alien. This was done by moving the alien in smaller increments.
While this redrawing technique work for the alien, my suspicion it is this technique that is causing redrawing slowdown to all other projectiles and loot drops from my ghost monsters.
Is my suspicion correct? I am really sure if drawing in small increments of pixel for an object really have a slowdown effect on another object that also needs to be redrawn. Let me know.
