Ah, of course, that makes perfect sense.
Thank you very much for pointing out my mistake.

I'm trying to make my own vector module, and for the most part it works (as far as I know), but in trying to add rotation I'm getting unexpected results. I'm not 100% sure whether the results are right, and my expectations are wrong, or vice versa. I'm rotating a 3D vector by an angle 'a', and then ...

Alternatively, you could use the modulo (https://en.wikipedia.org/wiki/Modulo_operation) operator.

So why can I do this: local b = true local t = { [true] = "1", [false] = "2" } print(t[b]) But not this: print( { [true] = "1", [false] = "2" }[true] ) I can replace the b with the value it holds, but I can't replace t with the value it holds? Is this just a f...

That makes far too much sense.
Thanks for explaining it to me.

So angles go from -pi/2 to pi/2, rather than 0 to 2*pi... Okay.

Thanks very much. It all seems to be working now.

So I was interested by Jimanzium 's idea about Sound Stealth . So I tried to implelemt something similar. Basically, the guards have a hearing range (shown by the blue circle when debugging) and a visibility cone (shown by the yellow cone when debugging). Thay have patrols which they're meant to fol...

I dunno if you ever played Fury3 (https://www.youtube.com/watch?v=6_8tSpXLuK8&t=1m0s), but how different d'you reckon the basic mechanics are to your starfox clone?

I'd completely forgotten about the existence of this game until I saw your screenshots.

I feel like I'm being stupid right now, but I don't get it. Velocity is the speed with direction Displacement is distance with direction. I don't get this bit: "in programming games there is ALWAYS velocity during movement". After all the movement, there is no movement. So there is no velo...

The way I do it is this: In another file, have your state: local state = {} state.__index = state function state.load() local this = {} setmetatable(this, state) -- this is the basic table that represents the state -- so initial values for properties of the state would be set here return this end fu...
