Log
From ZDoom Wiki
void Log(item(s));
Usage
Log will print something in the log area of the screen (top left), as well as logging it to the console. It uses the same parameter format as the Print function.
Example
script 1 (void)
{
AmbientSound("items/quaddamage", 127);
Log(s:"You've been granted Quad Damage!");
GiveInventory("PowerQuadDamage", 1);
Delay(25 * 35);
AmbientSound("items/quadwearingoff", 127);
Log(s:"Quad Damage is running out...");
Delay(5 * 35);
AmbientSound("items/quadgone", 127);
TakeInventory("PowerQuadDamage", 1);
}
