Chapter 13 ■ Animating Your Action Figure States: Setting the Image States Based on KeyEvent Processing
Figure 13-10. Duplicate the if-else structure from the isRight() structure into the isLeft() structure using framecounter
Now the time has come again to use the Run ➤ Project work process and test the run-cycle code, which now
exhibits a smooth, even, realistic run cycle. You can fine tune the running speed to slightly slower with a 7 or 8 value
or slightly faster with a 4 or 5 value. As we add faster vX values for running (say vX = 2) we can set the runningspeed to
3 or 4 to match this and make the game far more realistic.
One additional thing that I noticed as I was testing the code during this chapter that I want to correct here is the
sprite cel image for landing. I have been using imageStates(3), which is the “landed” image, which should actually
be better utilized with a collision situation. Let’s save this sprite cel image state for use later, in the collision detection
code development phase, to signify a collision with a surface (just landed or on impact image). The image I want
to use while the down arrow key is pressed is actually imageStates(6), which is the “preparing to land” image. The
revised Java code will look like the following, and is shown highlighted in Figure 13-11:
if(invinciBagel.isDown()) {
spriteFrame.setImage(imageStates.get(6));
}
