Unfortunately, I have not had much time to program since the last newsletter issue. The little time I have had has been spent learning line-cylinder collision detection. On a related note, I highly recommend the book "Real Time Collision Detection" by Christopher Ericson.

I have decided to simply mirror the completed side to save time.

The two columns closest to the viewer appear to be too far apart from the other columns in the row. This has been bothering me since I started work on the outline. After I mirrored it, I realized what the problem was. It looks strange because our eye will generally not see those columns, since they are too close to the edge of our vision. Those two columns are actually directly to the left and right of you.

I have determined that the area in the red box is what you would actually see.

This is the result.

This is the final image, for the preview release anyways. I've been working too long on this background, and I need to get back to work on the town. I'm planning on redrawing this after the preview is released, so cutting corners should be fine as long as it doesn't look too bad.

This week was a bit more active than last. It is interesting to still see newcomers to Stick Adventures Online. There have still been some forums posts happening so the community is still alive. Some talk about items and complexity of the game has taken place on the forums, and it is generally agreed that Stick Adventures Online will remain a simple type game with few additions.

A clever post on the Loradon 2.1 forums authored by Rman has been made to say that the game should not be declared dead, but people should play it. It will still be a long time before Loradon 3.0 is released, so why not play Loradon 2.1? The general idea is to make a new character and re-play the game, as to be fair and competitive with others. This should be a fun time if people decide to play. I would recommend if you have not tried the game, or if you want to get in on this, please create a new character and try to get online sometime. Loradon 2.1 is not a bad game, it is in fact fun despite a few glitches and lack of activity... Maybe we all can change it, though.

I was getting ready to post last week's newsletter when my computer suddenly crashed and S.M.A.R.T. reported that my HDD was bad. On further inspection, I found out that it was caused by the "Spin Retry Count" going 4 points under the breaking point. Not wanting to lose any data, I quickly backed up various files that the OneTouch backup software missed.

I recently downloaded and installed Windows 7 into a virtual machine, so I decided to try using it as my main OS. I spent the past week getting Windows 7 and various applications installed correctly onto a second drive. Surprisingly, I have only had one program break and that is most likely the fault of the program. Until they release a patch, I would not recommend installing the Jetico Personal Firewall into Windows 7.

A word of warning to anyone who uses the OneTouch backup software: Don't try and restore a backup manually. I am unsure if the software allows you to restore a backup from another OS installation, but I do not recommend copying the files directly from the backup directory. From what I can tell, OneTouch does not delete files from the backup. This might seem like a good thing, but it's not. Every file you moved from one place to another will be in both places in the backup, no matter how long ago you moved it. If anyone could recommend better backup software, please leave a comment. Thanks!

I finished the pillars on the right. Now that I have a reference, the left side should go by quicker.

Sorry, there isn't a community spotlight article this week.

Due to certain set-backs, overall progress has gone down to 69%. We should get back up there in no time though!

I am currently working on understanding the collision detection functions, to the point that I am able to re-write them. After I am done with that, I plan to create a program to test out the collision detection. If everything goes well, I'll release the program in a future newsletter issue!

This week was a bit quiet, but I'll write about some things I noticed.

For SAO, I would like to say Eeevil is doing a good job keeping the Bandits clan going even with CraterZ gone. Another thing I saw in the SAO forum was an upcoming mod by 009x3, titled 'Njm3.0' (Ninja Mod 3.0). It will be pretty cool judging that the last 2 were of decent quality and creativity.

Also, I see Bonkey is back. If you knew him from Loradon, you might want to say hi and give a nice welcome back.

As for the Loradon 3.0 progress... It went down again. I guess time had to be added or something, but this just means the game will be that much better, right? :D

Thanks to oliii from the gamedev.net community, I think the sphere-AABB collision detection and response is finally working! His solution to figuring out if the sphere is moving away from the AABB appears to work correctly in the demo, so I have high hopes for it working correctly in the actual game.

oliii's solution is quite simple actually. Simply project (dot product) the sphere's movement vector onto the collision normal and check the sign of the result. If it's negative, the sphere is moving towards the AABB.

oliii also showed me how to get "sliding" to work. "Sliding" is a way to prevent the moving sphere from stopping dead in it's tracks as soon as it hits something. If the sphere was moving at an angle to the collision surface, it will smoothly move along it rather than come to an abrupt stop. To do this, the distance the sphere was able to be moved is removed from the sphere's movement vector. The movement vector is then projected onto the collision normal and the result is multiplied by the collision normal. This creates a vector along the normal which, when subtracted from the movement vector, creates a new vector that will cause the sphere to "slide".

I made a mistake with the perspective, so I'm starting over. I'm drawing the skeleton on the computer this time. It's easier to make measurements now. When this is done, I'll shade the lines a faint grey and print it out on Bristol paper. I'll then use that as a base to draw over. I hope this works out.

I put together a quick example of what it will basically look like when it's done.

On the SAO forums, it's great to see Lee active again :D I see he sort of revived the Game Discussion section with a new thread. Also, another cool thing that happened this week was the making of an SAO trailer. It is cool to see a preview of the game so people can see it, and it is a great contribution from miotatsu!

From Loradon 3.0 there hasn't been much programming done. Don't be disappointed, because this is a way for InvisibleMan to take a break from the hard and confusing work, recently of collision detection, as he has described. GreyKnight has still been doing artwork, so things are happening behind the scenes of Twitter and the progress page! I hope some progress will go up, still.
