Subtle changes in 1.1 from 1.0

by Jason McIntosh · in Torque Game Builder · 12/29/2005 (11:48 pm) · 6 replies

I converted my current project from 1.0.2 to 1.1.0 alpha 2. Here are a couple subtle things that are worth mentioning to others.

- t2dVectorDistance() now returns a scalar, whereas it used to return a vector (the function was VectorDistance2D()).

- Blend colors are in the range 0..1 instead of 0..255.

- Is .safeDelete() more strict or something? Some crappy, bad, ugly code of mine that worked fine before caused crashes with the new version. I view this as a good thing, actually. Hopefully this means the internal memory management was improved. And it forces me to redo what was a big pile of dinosaur poop.

Otherwise the game was pretty easy to change over. My game is a complex bunch of code that touches many of T2D's systems, so it bodes well that there are no major problems so far. The alpha must be pretty bug free. Easy to take that for granted, but it really highlights Melv's huge talent and tons of careful effort.

Looking forward to more updates when TGE 1.4 integration is done! And special big thanks to the guy(s) that fixed the Mac project files (and another thanks for continued support of XCode 1.5). It compiled perfectly the first time.

Was this Little Gods? This is great to hear. I've been giddy to get the performance improvements into my current project but I've procrastinated for fear that my 90-some odd engine changes and sprawling scripts would prove to be a nightmare to convert.

At the very least I'll probably soft-launch with 1.0.2 soon and wait to integrate when the 1.4 core is in.

By the way, congrats on the Game Tunnel review and award!

Actually this is a new game with 95% new code. I'm not sure that I'll convert Little Gods at all, since that would also include redoing about 40 particle effects from scratch. Plus it's not as cleanly structured as this new game, so there's no telling what horrors would await me.

Thanks for the compliments, and good luck with your project! :)

Hmm, this crashing has persisted. It's very possible (even likely) that it's my code, but none of this happened before I converted to 1.1, and my code hasn't been modified significantly other than renaming things and a few patches to fix the above mentioned changes.

It crashes in platformMemory.cc. I get assert errors (line 909) that something is "Not an allocated block". I assume this means it's attempting to free memory that isn't allocated? Then it crashes (sometimes) in treeRemove(), platformMemory.cc, line 466.

I forgot about the ability to trace the script code, so I'll try that and see what happens.

Any other ideas?

Jason,

If you look at the call-stack, you should be able to see where it originated. I'd be very interested to help you here whether it's T2Ds fault or not.

Thanks for the help, Melv. Here's the crash report from the Mac version (I am not able to run it from a debugger on my low-end PC), but of course the TGE calls are the same, so it might still be helpful.

There's another crash that happens and it appears to have something to do with safeDeleting a static sprite. I'll try to reproduce that and post the crash report.
