i have been messing with this script and trying to get it to recognize names. i found a line that says if(self.player ==... so i thought i could do if(self.player == cybershot) that would work, but i get undefined variable. where is the variable..the main thing i am trying to do is learn how to script so this post will server many functions. also i am not sure if i need the return true at the end of the if statement and i don't know what the return true would do anyway so if you can explain that or what even any return means that would be great. thanks. Code: main() { trigs = getentarray("shoot_trig", "targetname"); for(i=0;i edited on Nov. 15, 2007 02:51 am by cybershot

The unitiliazed variable is cybershot. What you're trying to do is compare it to a string, in which case it should be if (player.name == "cybershot") As far as the return true; part, that depends on what you're trying to do. for any if statement, if the condition is true (player.name == "cybershot), then it performs the action after it, or the group of actions if they're surrounded by { }. In this case, if the player.name does equal "cybershot", then, unless i'm mistaken, the monitor_trigger function is exited, returning a value of true. Nothing further is done, and that function stops running. I think what you're trying to do is something more like this: while(1) { self waittill("trigger", player); if (player.name != "cybershot") player suicide(); } The big thing is that you need to have the self waittill("trigger", player); before the if statement. The first reason is that the waittill declares the player variable (another possible undeclared variable), and generally, you want the trigger to be triggered before you do any checks. With this code, once the trigger is activated, it checks the player's name, and if it is not "cybershot", then the player dies.

If you type /developer 1 in the console before you run your map, and then bring up the full console (shift+~), where it tells you that you have an uninitialized variable, it should show you the line it's from and put an asterisk underneath the variable that it uninitialized.

I just tried this and it worked: Code: main() { trigs = getentarray("shoot_trig", "targetname"); for(i=0;i Not sure why it isn't working for you. edited on Nov. 15, 2007 11:22 am by (VM)Monkey

it didn't work for me because i was missing the quotes around my name if(self.player != "cybershot"); i had if(self.player != cybershot) i also had a space between the if (. now it wouldn't work with the color codes for some reason. i had to take out the color to get it to work for me. but it's working now. thanks for you input on this.. one other question if i may? i thought all if statements needed to have their own curly braces "{" why doesn't the if statement in this code need a curly brace? so i thought it would have looked like this if(player.name != "cybershot); { player suicide(); }

Sorry it took so long to respond. The best way I can explain it is to consider the brackets ({ and }) as a sort of box. Anything between { and } is inside that box. The if, else, while, for, etc statements only run the next command. Think of them as a person who you can only hand one thing to at a time. For example, if you had for(x=0;x<5;x++) iprintlnbold(x); iprintlnbold("hi"); it would print 0 1 2 3 4 hi Using the analogy of the person who can only be handed one item at a time, if you take a box, and fill it full of stuff, you can hand him the full box, and he'll take it, because it's only "one" item. The same is with the brackets. If you put a bunch of statements in the brackets, you can tell the function to run this "one" command. For example, for (x=0;x<5;x++) { iprintlnbold(x); iprintlnbold("hi"); } it would print 0 hi 1 hi 2 hi ... etc Anyway, it's not necessary to use brackets if you're just doing one command. It does help to make it easier to read sometimes though, unless you religiously indent your code. Hopefully that didn't confuse you more. edited on Nov. 17, 2007 01:30 am by (VM)Monkey
