I'm trying to make aimbot but I already failed in maths and trigonometry sux and all math sux but I want to make aimbot so I will be great-full to anyone who will help me with maths I have my XYZ coords, Enemy XYZ coords, and camera XY angle(eye position what we call it probably) I just want to know how can I calculate accurate camera XY angle to write at im writing it in LUA

My maths also sux, but maybe something like this:

Code:

-- Calculate distance
function distance(chicken,you)
return math.sqrt( (chicken.x - you.x) ^2 )
end

-- Camera Angle
function angleTo2DVec(startX, startY, angle, distance)
angle = angle * (math.pi/180)
return startX + math.cos(angle)*distance, startY + math.sin(angle)*distance
end

--testing values
local x, y = 100, 300
local angle = 45
local distance = 300

local newX, newY = angleTo2DVec(x, y, angle, distance)
print(newX, newY)

or use math.atan2

Code:

-- Angle between 2 points
local angle = math.atan2 ( centre.y - target.y, target.x - centre.x)
-- OR
local angle = -math.atan2 ( target.y - centre.y, target.x - centre.x)

I really appreciate this brother and would like to ask few more things,
1. you only used X axis to calculate distance between two 3d object, why did you ignore y and z axis? is it not necessary for aimbot?
2. in function angle2dvec you passed 4 variables, x,y,angle,distance, where x and y are my camera x and y angles(I think so) and the distance is what we calculated above right? but what does that angle means? how to get/calculate it?
If you feel so please explain further and few things I would like to mention is that im making this aimbot for gta vice city, and all values are float type.
3. about this

Code:

-- Angle between 2 points
local angle = math.atan2 ( centre.y - target.y, target.x - centre.x)
-- OR
local angle = -math.atan2 ( target.y - centre.y, target.x - centre.x)

how can I find the center x an y? by dividing distance by 2?

Here are a few helper funcs I wrote for some stuff of mine. Distance and degree/radian related:

Code:

----------------------------------------------------------------------------------------------------
-- func: math.distance2d
-- desc: Returns the 2D distance between two sets of coords.
----------------------------------------------------------------------------------------------------
function math.distance2d(x1, y1, x2, y2)
local x = x2 - x1;
local y = y2 - y1;
return math.sqrt((x * x) + (y * y));
end

----------------------------------------------------------------------------------------------------
-- func: math.distance3d
-- desc: Returns the 3D distance between two sets of coords.
----------------------------------------------------------------------------------------------------
function math.distance3d(x1, y1, z1, x2, y2, z2)
local x = x2 - x1;
local y = y2 - y1;
local z = z2 - z1;
return math.sqrt((x * x) + (y * y) + (z * z));
end

----------------------------------------------------------------------------------------------------
-- func: math.degree2rad
-- desc: Converts a degree to a radian.
----------------------------------------------------------------------------------------------------
function math.degree2rad(d)
local pi = 3.14159265359;
return d * (pi / 180);
end

----------------------------------------------------------------------------------------------------
-- func: math.rad2degree
-- desc: Converts a radian to a degree.
----------------------------------------------------------------------------------------------------
function math.rad2degree(r)
local pi = 3.14159265359;
return r * (180 / pi);
end

A1:
X, for the distance, means not as X-axis. That means as the centre of the objects.
Z-axis need for flying objects or top-bottom view.

A2:
Calculate angle measures example:

distance A to B (AB = hypotenuse side) = 8
distance A to C (AC = adjacent side) = 6
the measure of angle A ?.

cos(A)=AB/AC
cos(A)=6/8
angle A = cos^-1 x [6 / 8]
angle A = 41.41 degree

Calculate Angle Between Source Object (You) And Destination Object (Chicken):

Code:

function angleBetween ( srcObj, dstObj )
local xDist = dstObj.x-srcObj.x ;
local yDist = dstObj.y-srcObj.y
local angleBetween = math.deg( math.atan( yDist/xDist ) )
if ( srcObj.x < dstObj.x ) then
angleBetween = angleBetween+90
else
angleBetween = angleBetween-90
end
return angleBetween
end

A3:
Finding the centre of 2D object and calc the distance, for example:

Code:

f = createForm()

you = createPanel(f)
you.setSize(20,20)
you.setPosition(30,40) --left,top

chicken = createPanel(f)
chicken.setSize(20,20)
chicken.setPosition(80,90) --left,top

---- ======= #1 Method

function distance_getDiff(x1,y1,w1,h1, x2,y2,w2,h2)
return x2 - x1 - w1, y2 - y1 - h1, w1 + w2, h1 + h2
end

youX, youY, youW, youH = 30, 40, 20, 20
chickenX, chickenY, chickenW, chickenH = 80, 90, 20, 20
distanceBetweenYouAndChicken = distance_getDiff(youX, youY, youW, youH, chickenX, chickenY, chickenW, chickenH)
print(distanceBetweenYouAndChicken) -- = 30

---- ======= #2 Method

-- Get centre point of objects
H_centreYou = math.floor(you.width/2)
V_centreYou = math.floor(you.height/2)
centreYou = math.floor((H_centreYou + V_centreYou) /2)
print(centreYou) -- = 10

H_centreChicken = math.floor(chicken.width/2)
V_centreChicken = math.floor(chicken.height/2)
centreChicken = math.floor((H_centreChicken + V_centreChicken) /2)
print(centreChicken) -- = 10

-- Calc distance between 2 objects point to centre object
distanceBetweenChickenAndYou = math.sqrt( (centreChicken - centreYou)^2 )
print(distanceBetweenYouAndChicken) -- = 30

Anyhow, atom0s have you better solutions. And just remember as I said, my math is sux. Rolling Eyes

Answer 3 started to scaring me, im going to try these things you mentioned

1 more thing, does the data type matters? I mean all the values I have are in float, does this effect the calculation in any way?

I think the data store in the game as floating values.
Please, read the code from the link provided by Aylin.
