When we run our pygame's code, our target scope image will NOT move, but our do robots generate. We are trying to use our arrow keys to move them and I included all of our code.
Commented out under our newest trial code for moving are two other things we tried.

. There are no error messages, but it won't move. We've tried a ton of different things (that aren't included) and looked up a lot of websites so please help us. Thanks
To move object you have to not only change x,y and update screen (send buffer to video card which will display it) but also clean buffer, draw image in new place in buffer (blit()).
This code shows only working move_target. I skiped rest of code.
I keep position in target_rect which is pygame.Rect. You can use it to blit(img,rect) but later you can also use to check collision rect.colliderect(other_rect)
