you need to go to the steam support section and file a ticket.

How do you know if a 518 is 1600 dpi?

in your hudlayout.res make sure you have

xHairCirclePulse
{
"controlName" "CExLabel"
"fieldName" "xHairCirclePulse"
"visible" "0"
"enabled" "1"
"zpos" "2"

"xpos" "c-100"
"ypos" "c-100"
"wide" "200"
"tall" "200"

"font" "xHairCirclePulse"
"labelText" "i"
"textAlignment" "center"

"fgcolor" "0 200 0 255"

and in hud_animation_tf.txt make sure you have

event DamagedPlayer
{
Animate xHairCirclePulse FgColor "255 0 0 255" Linear 0.0 0.1
Animate xHairCirclePulse FgColor "0 255 0 255" Linear 0.2 0.200001
}

this will make your circle green and blink red on damage.

In the KBNHud the hud circle xhair is nice as scout but i dont like it for many other classes. Is it possible to make it visible just for 1 or 2 classes but off for the rest?

WalMart doesnt provide Wifi as it screws with their wifi for all of their systems.

Actually, that works pretty well, I should be able to get it working, ill test it out shortly. Thank you!

edit: worked perfectly, thank you so very much

so i have KBNhud and it comes with that nifty little circle around your ingame xhair that blinks when you do damage but its black.

Ive messed witht he hudlayout thing and made it:
"Resource/HudLayout.res"
{
xHairCirclePulse
{
"controlName" "CExLabel"
"fieldName" "xHairCirclePulse"
"visible" "1"
"enabled" "1"
"zpos" "2"

"xpos" "c-100"
"ypos" "c-100"
"wide" "200"
"tall" "200"

"font" "xHairCirclePulse"
"labelText" "i"
"textAlignment" "center"

"fgcolor" "0 200 0 255"

but the green color only lasts until i hit someone, then it goes back to black. How would I change this so that it still blinks red when i hit someone but goes back to green not black?

PS: i know nothing about scripting or hud editing
