Meanwhile in HUDPaint()...
[lua]
draw.RoundedBox( 6, 190, ScrH()-64, 74, 300, Color(200,10,10,SAlertAlpha) );
[/lua]
This thing is supposed to making the small drawn box fade in/out, or pulsate, or whatever you want to call it. However, it will not work. A quick print debug informed me that the function is running properly, so apparently the alpha is not getting set properly. This is all in cl_init.lua and the external values are working fine (i.e. stamina). I'm not sure what I'm doing wrong, but it's probably just a really stupid mistake like a syntax error or something.
Oh yeah, that makes sense. Testing.

Still isn't working. I guess that fixed one thing but there must be something else wrong.
Just use a sin wave, it's a lot easier to use.
[lua]hook.Add("HUDPaint", "AlphaTest", function()
local speed = 4 -- how fast to make it tick
local tick = ((math.sin(CurTime() * speed)+1)/2) * 255 -- Creates a sin wave that goes from 0 to 255
local col = Color( 13, 200, 12, tick )
draw.RoundedBox(8, 20, 20, 80, 80, col)
end)[/lua]
Here is a basic example.
Oh, that's clever. Tweaked, saved and loading.
[editline]10:40AM[/editline]
Not working. I'll look for what I did wrong.
Hook 'Alphatrans' Failed: includes/modules/draw.lua:184: attempt to index local 'color' (a nil value)
[lua]
hook.Add( "HUDPaint", "Alphatrans", function()
local Stamina = LocalPlayer():GetNWInt( "stamina" );
local alpha = Color( 200, 10, 10, alpha );
local speed = 1;
if Stamina <= 40 && Stamina >= 15 then
local dosin = true;
local speed = 1;
elseif Stamina < 15 then
local dosin = true;
local speed = 3;
else
local dosin = false;
end
if dosin then
local alpha = ((math.sin(CurTime() * speed)+1)/2) * 255; -- Creates sin wave from 0 to 255
else end
draw.RoundedBox( 6, 190, ScrH()-64, 74, 300, alpha );
end )
[/lua]
The reason I'm checking for dosin is because whenever I set speed to 0 so that it does not do anything, it returns an error about a nil value and fails. This is the only way I could think to do it.
[editline]10:43AM[/editline]
Whoops forgot to replace one of the "color"s with "alpha". Loading to test if it's fixed.
[editline]10:45AM[/editline]
The colored box is drawn but it is drawn regardless of the value of the stamina and does not have a sin 'pulse'.
[editline]10:48AM[/editline]
I'll try moving the dosin check to drawing, not the sin function. That's what I should have done.
[editline]10:51AM[/editline]
Didn't work, but i realized that I have two 'local alpha's being set. Fixed and loading to test.
[editline]10:53AM[/editline]
Gawd dommit still not working. Debug shows that the local variables are being set appropriately.
[editline]10:55AM[/editline]
Lol I'm stupid, crisscrossing the local variable names again. ANOTHER LOAD
Many things are wrong with that. In the color variable you have an "alpha" argument which you never set so it is nil. You're creating a local "alpha" variable in "if dosin then" so it only exists in that statement. You're not giving draw.RoundedBox a color for it's color argument, you're giving it a nil value.
Here is an example I did using health:
[lua]hook.Add("HUDPaint", "AlphaTest", function()
local HP = LocalPlayer():Health()
local speed = 1
local alpha = 255
if HP <= 40 and HP > 15 then
speed = 3
alpha = ((math.sin(CurTime() * speed)+1)/2) * 255
elseif HP <= 15 then
speed = 6
alpha = ((math.sin(CurTime() * speed)+1)/2) * 255
end
local col = Color( 13, 200, 12, alpha )
draw.RoundedBox(8, 20, 20, 80, 80, col)
end)[/lua]
ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffuuuuuuuuuuuu
[lua]
hook.Add( "HUDPaint", "Alphatrans", function()
local Stamina = LocalPlayer():GetNWInt( "stamina" );
local alpha = Color( 200, 10, 10, sinalpha );
local speed = 1;
local sinalpha = ((math.sin(CurTime() * speed)+1)/2) * 255; -- Creates sin wave from 0 to 255
if Stamina <= 40 && Stamina >= 15 then
local dosin = true;
local speed = 1;
elseif Stamina < 15 then
local dosin = true;
local speed = 3;
else
local dosin = false;
local speed = 1;
end
if dosin then
draw.RoundedBox( 6, 190, ScrH()-64, 74, 300, alpha );
else end
end )
[/lua]

Disregard the above, I made it without seeing CowThing's latest post. Thanks for the tips, that single post taught me a handful of things. This is what I have and I'm about to test it.
[lua]
hook.Add( "HUDPaint", "Alphatrans", function()
local Stamina = LocalPlayer():GetNWInt( "stamina" );
local speed = 1;
local alpha = 255;
if Stamina <= 40 && Stamina >= 15 then
speed = 1;
alpha = ((math.sin(CurTime() * speed)+1)/2) * 255;
elseif Stamina < 15 then
speed = 3;
alpha = ((math.sin(CurTime() * speed)+1)/2) * 255;
end
local col = Color( 200, 10, 10, sinalpha );
draw.RoundedBox( 6, 190, ScrH()-64, 74, 300, col );
end )
[/lua]
[editline]11:14AM[/editline]
Woot I think I got it to work.
[lua]
hook.Add( "HUDPaint", "Alphatrans", function()
local Stamina = LocalPlayer():GetNWInt( "stamina" );
local speed = 1;
local alpha = 0;
if Stamina <= 40 && Stamina >= 15 then
speed = 3;
alpha = ((math.sin(CurTime() * speed)+1)/2) * 255;
elseif Stamina < 15 then
speed = 6;
alpha = ((math.sin(CurTime() * speed)+1)/2) * 255;
end
local col = Color( 100, 10, 10, alpha );
draw.RoundedBox( 6, 190, ScrH()-64, 74, 300, col );
end )
[/lua]
[editline]11:18AM[/editline]
Awesome, it works now I just need to tweak the color/speed. Thanks CowThing.

Final code:
[lua]
hook.Add( "HUDPaint", "Alphatrans", function()
local Stamina = LocalPlayer():GetNWInt( "stamina" );
local speed = 1;
local alpha = 0;
if Stamina <= 40 && Stamina >= 15 then
speed = 5;
alpha = ((math.sin(CurTime() * speed)+1)/2) * 255;
elseif Stamina < 15 then
speed = 10;
alpha = ((math.sin(CurTime() * speed)+1)/2) * 255;
end
local col = Color( 255, 0, 0, alpha );
draw.RoundedBox( 6, 190, ScrH()-64, 74, 300, col );
end )
