Project Aurora, post 8, Solving problems
|
Last week I still had problems with light circles overlapping so I booked a private time with my teacher Tommi to see if he could help me solve this problem. We sat down and I explained the problem to him. I wanted to get rid of the black border when two lightcircles overlap. (See picture)  He came up with a solution where I could try using sf::Image to manipulate the pixels to get rid of the borders. It sounded like a good idea. I was about to get started and Tommi about to leave when I asked if maybe sf::BlendMode could be used. We checked what kind of blendmodes SFML had and he told me to try BlendMultiply and it worked great!
It saved me atleast a days work.
 (the light is not centered around the player for testing)
Another thing happened today when I sat with my groupmate Oscar and the problems he had with getting collisions to work. He had som collision check code that worked perfectly in a prototype but for some reason it didn’t work in our project. I looked at it and it looked good and because the collision behaved so strange I told him to try to limit the collision area by adding more walls just to try to narrow the problem down. Something I have learned with many days of problems with my light circle. He tried it and we figured out what the problem was within 5 minutes.
Conclusion:
Bouncing Idea’s with people really help getting to a solution when the solution is unknown.
