EDIT: OH!!!!! it works!!! It seems that at one point it was fixed However the wrong HTML file was opening up so the wrong code was running. I feel stupid, that should have been obvious.
But THANKYOU!!!
Its so awesome to actually get some help with this stuff. whenever i ask for some help anywhere else or even ask my teacher im usually ignored or get useless advice. (end of edit)
Im making a game for my final project in a java class. I just got mouse aiming to work using AffineTransform, however When ever the player object rotates to 90 degrees(or a multiple of it), it does this weird stutter thing. Heres the code im specifically concerned with.
g2.drawImage(img, x_pos,y_pos,this);
AffineTransform oldTransform = g2.getTransform();
g2.setTransform(AffineTransform.getRotateInstance(radAngle,x_pos + (img.getWidth() / 2),y_pos+(img.getHeight() / 2)));
Could someone please help me figure out how to fix this? my project is due tomorrow so im slim on time. Here are the images i use
Heres the code.
