Gunturrets work

Just finished implementing the gun turrets, we now have enemies in the map. Although work is a big word the render thats all for today.
Ow and I fixed a nasty memory leak in my particle system today without having to redesign it all.

On the laptop front of things they haven't come by my place today sadly enough hope they will deliver it tomorrow. Other wise i got more waiting on it to do and i don't want to wait.

Particle Systems Continued

I changed the particle system slightly it now more resembles the nebula devices one. Although mine still does the interpolation on particle level instead of on emitter level. If we do it on particle level it looks a lot nicer than on emitter level. Here is a screen dump of a fire effect:

If the particle size isn't set you get a nice effect as well, this happens because particles are then spawned with a infinite size. Here is an example of that:

Side note on the laptop I got a mail today that they got it and are sending it to me today. Yay I am really happy to get this one no more dinners at 23:00. I can eat at normal times again and still do some work.

Laptop Confirmation

Today I got the confirmation for my laptop, it will arrive at Laptops4u tomorrow or Thursday and then they will ship it to me. Next week I'll have my new laptop, finally i can work at home on my ACW. Too bad it's due in two and a half weeks, still might enable me to get shaders to work in the 2 weeks remaining. As of now I have texturing and point lights working through vertex and pixel shaders. Spot lights are hard to implement in shaders. The problem with shaders is they are not debug-able which makes it kinda hard to write them. Although the result is a lot nicer than the fixed function pipeline behavior. Planes can now consist of 4 vertices's and still light will look good on em instead of the hundreds of points I am using now.
Here is another particle system effect:

Long overdue post

Ok this post is long overdue and it's about all the crazy stuff thats going on on Fridays over here.
This story starts on halloween when we got invited for a party that on the last minute didn't happen. Lucky for us there was another party going on somewhere else. When we walked in to this party, of course we weren't invited but who cares, there were only girls there so we felt well this is gonna be a good night. After we were in for 5 minutes this girls comes up to use and starts yelling at us we we weren't dressed up, and what we were doing there. This lasted for a bout 10 minutes and afterwards we actually had a good laugh with her. This night ended a bit weird though.

The next party was that friday at asylum the night lub an campus it was an ISA party, you know the society that signed me up by having a party, good way to get members though. This was a weird night as well as i couldn't get drunk that night and I was drinking double vodka shots. In retrospect though i might have switch to hard liquor to early that night.
To continue the next week we crashed a party again, he sounds like we are getting good a this thing here. This party turned out to be a birthday party, we a group of about 20 people just walked in and started drinking. Here one of my friends try to climb a wall, more accurately what happened was he walked into the wall. He ran up to it and jumped but couldn't get high enough so he sacked into the wall.
This is also the night the legend of the giraffe was born. See picture blow the guy eating the leaves.

Then finally we come to two weeks ago this was a crazy night as well, also the most expensive one I have been on here. 7 quid 50 for 2 shots of brain hemorrhage. This was just basicly a pub crawl that ended up at some friends house were I saw the greats pile of dishes ever.

As you can tell i don't really remember everything that happens on Friday nights here but thats just because we start to early.

Particle Systems

Today i got the particle system for the end sequence of the game done. Although done is a big word as it still massively memory leaks, but we brush that aside for the moment. The particle system also serves another purpose in the game, as lasers hit a wall there will also be a particle explosion. The only things left to do for the ACW now are:

• Recording and play back functions
• gun turrets
• Alternate 3d person view
• and HUD

Need to pitch a game idea tomorrow, and it has to do with the environment. During Christmas I need to make an A1 poster for this idea. The idea is to have an adventure game to build a bio diesel gas producer and a car to run it on. Then the end of the game is to race it as environment friendly as possible. It's not a grand and great idea but it will have to do.

Multi texturing

Finally I got multi texturing working!!!!!!!!!!!!!!!!
The problem was that I was calling the wrong function to set up the texture stage, instead of calling glActiveTexture is was calling glClientActiveTexture. The last one you use when you tell GL where to find the texture coordinates. Well enough tech talk here is how it looks.

Lasers and Scorchmarks

In the last two days I revised the switches they now look a lot sharper, added lasers and their scorch marks. While doing the scorch marks I also figured out why multi texturing wasn't working, OpenGL demands two vectors or arrays of texture coordinates. So we can't reuse the texture coordinates from one stage to use in the next stage, which is a pain. Or if some one knows how to please let me know because that would make things look so much nicer. As for now the only place I use multi texturing is in the scorch marks, they have a color and an alpha map. There is still something wrong with them as the are effected by the material of a laser, although before I start drawing them I reset the material.

On a side note I ordered a shiny new laptop last week a ASUS g1s. It still hasn't arrived but it should do in the end of this week or beginning of next. This machine is the most money I have ever spend on a PC or Laptop. It's gonna be sweet to have it though means I can go home earlier in the day and work at home instead of being in the labs all the time.
