Clumsy sheepoid.

17th September 2011

No screen shots or videos to show you this time, but I have still been working on Woolly Jumper. It is still sort of shaping up quite nicely, apart from that I came across some design faults in the game. (Go on, blame the coder). It turned out that the sinus mode which I originally used for the game wasn't all that good. The sinus was all over the place. That's not what we really want for a game don't you agree?. Well the good news is that I have renewed the sinus movement for the aliens, and after they get shot - they will disappear as they should (and not reappear on screen).

The second issue was the background. When the player jumps out of the screen, it seems to mysteriously die outside the border. This was quite a weird thing that was going on. I do have to admit. Anyway to resolve this problem I lowered the border jump height. So that no collision's made up there.

The next issue was that I programmed the lives and sprite/sprite collision. The sheep has too much on it's plate (Thanks for pointing this out Shaun) where the enemies appear on screen frequently. Oh dear :( We don't really want that to happen do we?. So I have come to a decision to add a delay/timer before letting loose the next batch of aliens. This will give the player chance to jump over platforms on to the next one. To make the player die. I added a little routine which made the sheep jump to the top of the screen, then fall into the water. The basic idea is to have an amusing frame, for where the sheep goes up, then add a splash sprite to make it look as if it had jumped into the water. I also did some jingles where one made the sheep scream if hit, then a splash sound for when it ends up in the water.

One final issue which I spotted, but pointed it out to Shaun, was a mapping fault. Basically the platforms were too far from each other in parts of the map, making it virtually impossible for the poor sheep to jump over. I also noticed a silly bug today in which killed the sheep when on top of the shaded area of the platform where the meat hooks hang. That will be simple enough to fix. Simply locate the charset number

I also had two .D64's from Shaun, featuring his new sprites for the game. So I loaded up the Sideways SEUCK (As Shaun used this to make them) and attached the .D64 with (what was meant to have been) the source files. Sadly I could not get those to load. It turned out that the disk image was corrupt as the file name ended with a *PRG inside the disk directory. This is known as a splat file. Perhaps the .D64 wasn't detached from VICE before I received it. Anyway I received the latest disk with the sprites. Those were Power Ups, alien species and of course the player animations. Looks absolutely great :) I will be looking forward to the final sprites :)
