Question about client performance in dx


Recommended Posts

So today I was making a new HUD for players in dx, due this HUD will be displayed all the time I started thinking about how I can optimize it as maximun as possible...

Going from this classic code:

local screenW, screenH = guiGetScreenSize()
local scaleX, scaleY = screenW/1920, screenH/1080

addEventHandler("onClientRender", root, function()
    dxDrawText("30/", screenW * 0.7786, screenH * 0.0648, screenW * 0.8380, screenH * 0.1426, tocolor(241, 173, 11, 255), scaleX, scaleY, dxfont0_excelsior_sans, "left", "top", false, false, false, false, false)
    dxDrawText("9999", screenW * 0.8354, screenH * 0.0657, screenW * 0.8807, screenH * 0.1130, tocolor(241, 173, 11, 255), scaleX, scaleY, dxfont1_excelsior_sans, "left", "top", false, false, false, false, false)
end)

to this "more optimized" one:

local screenW, screenH = guiGetScreenSize()
local scaleX, scaleY = screenW/1920, screenH/1080

local hudSizes = {
	(screenW * 0.7786), (screenH * 0.0648), (screenW * 0.8380), (screenH * 0.1426), (screenW * 0.8354), (screenH * 0.0657), (screenW * 0.8807), (screenH * 0.1130)
}

addEventHandler("onClientRender", root, function()
	dxDrawText("30/", hudSizes[1], hudSizes[2], hudSizes[3], hudSizes[4], 0xFFF1AD0B, scaleX, scaleY, dxfont0_excelsior_sans, "left", "top", false, false, false, false, false)
	dxDrawText("9999", hudSizes[5], hudSizes[6], hudSizes[7], hudSizes[8], 0xFFF1AD0B, scaleX, scaleY, dxfont1_excelsior_sans, "left", "top", false, false, false, false, false)
end)

As you can see I replaced the multiplications with some variables that represent the calculations (so it doesn't need to multiply the number everytime that "onClientRender" is triggered) and the same goes for the tocolor function.

So as far as my understanding goes this would increase the performance, right? or atleast that's my question doing this would have any impact in clients performance? or it's just complicating the code for no reason?

I reccomend to use this resource to monitor the usages of your scripts:

But basicly, I dont believe, that your precalculate will decrease the usage. Multiply two number is not a hard task for the CPU, even in every frame. 

Well, I haven't shown the complete code in this post, we're talking about 30+ multiplications, anyways thanks for posting that script I didn't know we had something like that, so useful
