... And the bonus ball is ...

27th June 2012
I only had 2 hours spare, which gave me some time to work a little more on Trance Sector, since finishing Escape from Zaphod  using the 3D construction kit last week (Hard work).. I took a look at the sprite data to work out what the ball's value should be, and created a frame table in which would indicate the colour for the particular bonus object. I created a few values to check the direction of which direction the ball should be bouncing. A few subroutines were also programmed in to get that ball moving according to direction. Yep, it bounced around the screen how I hoped, but was a bit too fast. So I slowed it down by adding a speed delay to it. I also created a sub routine that could cycle the colour of the bonus ball. The same was done for the frame type. Since I didn't want the ball colour and frame cycle to go too fast, I just had to sort something out to stop this. So I created a delay. Now the objects and colours are cycling to how I hoped they would. 

... and here's the result so far. :)

As you can see, I have a ball bouncing around the screen, but what use is it where there's no way of being able to touch the object to destroy it? Well, because of being short of time I had because of work. This will be resolved hopefully some time this Friday, if I don't get called or text into work that is :) The plan in general will be to get the bouncing ball to disappear if one of the seekers/missiles hits the ball. Whatever frame the ball last had will result 100 points, 200 points, 500 points, an automatic bomb to destroy all seekers or a lit up E-X-T-R-A (In which, when fully lit will award the player an extra life). I better work on the collision and checks for what's resulted from the ball.
