Spamocalypse 0.7.2: How not to handle sound detection


File this one under “Aceade is an eejit”. I broke the spammers’ sound detection, and I’m not sure when I did that! I didn’t realise that until today, when I started trying to make them react to misses from the SQL injector.

The root cause of this bug is that I had converted their sound detection to use a Coroutine with a 0.2-second interval, rather than OnTriggerStay. OnTriggerStay runs on the physics timestmp, which by default is 50 times a second - which is a bit more intensive than I wanted. However, when converting it, I forgot to actually make it run more than once (hint: use a while loop)! So, the spammers were effectively deaf, which pretty much defeated the point of the game.

Another thing that was broken was their Sockpuppet detection. This was a physics issue - I had set the Spammer layer to ignore collisions with the Decoy layer. However, that’s the layer which is supposed to contain the Sockpuppets!

I think these were introduced while trying to improve performance a month ago. Those performance issues I ran into were ultimately caused by using MeshColliders as trigger areas for sound and line of sight detection, which is generally a bad idea. However, when I got those fixed, I didn’t think to check if I had broken anything else. I really need to find a way to test more thoroughly…

Been working lately on lots of 'behind-the-scenes' boring stuff that no one really cares about, so here’s a guy playing the sax for some reason.

If you have more of an acquired taste, the restaurants in Niravasi have you covered! Maybe skip the salad bar, though.

Some time ago, we posted a screenshot of the Mexico level. A curiosity about it is that, like some other scenarios of the game, it was inspired by a real landscape, The Basaltic Prisms of Santa María Regla. It is one of the natural wonders of the country!
