Call function or repeat

[Drakath]

I have a script which uses about 15 getDistanceBetweenPoints3D functions.

Would it be more efficient to make this function:

function getDistToElement(element,Px,Py,Pz) 
    local x,y,z = getElementPosition(element)    
    return getDistanceBetweenPoints3D(Px,Py,Pz,x,y,z) 
end 

and use it instead of all other getDistanceBetweenPoints3D?

You're still calling it 15 times so this won't make a big difference.

Actually, making a entire function for it would be less efficient as you are nesting a new function and calling it 15 times. It would take less time & less memory size just to call the MTA function directly.

Example:

Execution Data: 0.02s memory: 2496KB

local var = "xD" 
  
print(var) 
print(var) 
print(var) 
print(var) 
print(var) 
print(var) 
print(var) 
print(var) 
print(var) 
print(var) 
print(var) 
print(var) 
print(var) 
print(var) 
print(var) 
  

Execution Data: 0.03s memory: 2540KB

function out(value) 
    return print(value) 
end 
local var = "xD" 
  
out(var) 
out(var) 
out(var) 
out(var) 
out(var) 
out(var) 
out(var) 
out(var) 
out(var) 
out(var) 
out(var) 
out(var) 
out(var) 
out(var) 
out(var)

ciber how do you calculate the time of Execution?

[Drakath]

Thanks for the information.

No problem.

ciber how do you calculate the time of Execution?

In the case that you are testing native Lua functions, i just use a Lua engine. Otherwise, you can calculate execution time approximately using getTickCount

This function returns amount of time that your system has been running in milliseconds. By comparing two values of getTickCount, you can determine how much time has passed (in milliseconds) between two events. This could be used to determine how efficient your code is, or to time how long a player takes to complete a task.
