Ask you the question of the anti trigonometric function - Ezzz - 24.07.2018

I saw wiki, but I only found these trigonometric functions of floattan, floatcos, floatsin.
I want to make a script that can tell whether the player is facing a OBJ. I think I need an inverse trigonometric function to complete the operation.
But I didn't find the sentence of inverse trigonometric function, so I asked the forum you, please help me, thank you.

Did you look into this? https://sampwiki.blast.hk/wiki/GetPlayerCameraTargetObject
EDIT:Inverse of something is usually '1/n' In this case:

PHP код:



floatcosec(Float:number)

{

    return 1/floatsin(number);

}

//cotagent and secant like the above way.

They're already defined in a_samp.inc, but just not documented on the wiki.

Код:

native Float:asin(Float:value);
native Float:acos(Float:value);
native Float:atan(Float:value);
native Float:atan2(Float:x, Float:y);
