trigonometry in programming - thefatshizms - 01.07.2013
Hello, I've been learning trigonometry lately in my free time and noticed that its often used in programming (as well as in sa-mp). I was wondering, what can trigonometry be used for? and could you give me some examples of code to get my head through the concept.

Probably the most famous and one of the most simplistic would be getting a position in front of the player https://sampforum.blast.hk/showthread.php?tid=325872 but you could also use it to say calculate the rx, ry of a slope using map andreas. You could calculate animation frames for throwing an object (sine) the uses are endless.

Get direction of Turrent gun to face and shoot player
do stuff with NPC (facing, running, etc..

Sorry if this is a stupid question.. (Haven't been doing trig for long + only in my spare time (my maths teacher isn't teaching me it yet :c ) )
In the function "Floatsin" it takes an angle.. I thought in order to get the sin of something you need to know the size of the hypotenuse and the size of the opposite side.
Re: trigonometry in programming - MP2 - 01.07.2013
I think that's sin-1. sin(angle) sin-1 (asin or arcsin or something) of the opp/hyp.

Okay thanks, I thini I pretty much get it now. The only thing I don't really get is how Floatsin works.

What do you mean 'how it works'?

Sine is approximated by using Taylor series
