I have a pixel perfect method that works fine except when one or more of the images are flipped(or rotated, but I wont fix that).
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35
| public static boolean pixelPerfect(GameObject obj1, GameObject obj2) { Image2D image1 = obj1.getImage(); Image2D image2 = obj2.getImage(); int top = (int) Math.max(obj1.currY, obj2.currY); int bottom = (int) Math.min(obj1.currY + obj1.height, obj2.currY + obj2.height); int left = (int) Math.max(obj1.currX, obj2.currX); int right = (int) Math.min(obj1.currX + obj1.width, obj2.currX + obj2.width); boolean flipped1 = image1.isFlipX(); boolean flipped2 = image2.isFlipX();
for (int y = top; y < bottom; y++) { for (int x = left; x < right; x++) { int colorA; int colorB; if(flipped1) colorA = else colorA = image1.getColor((int) (x - obj1.currX), (int) (y - obj1.currY)); if(flipped2) colorB = else colorB = image2.getColor((int) (x - obj2.currX), (int) (y - obj2.currY)); if (colorA != 0 && colorB != 0) return true; } } return false; } |
How do I calculate the current pixel to check if the image is flipped horizontally?
