ThinkInvisible:
I had several ideas for scripts but i'm missing a few keyboard functions.
-How do i detect if a key is being held down/is released/was just pressed?
-How do i detect what keys are currently being held down? If i know the above i could just set up a loop or something.
-How do i simulate a keypress?

And a few other things i should ask about:
-Exactly what does the operator "^" do?
-I'm also trying to make a mod that creates crosshairs over other players. Just for coolness. How would I convert a 3D position into a 2D position, and test if it would be offscreen?
-Why does player.setPosition("x y z"); crash the server, as opposed to player.position = "x y z"?
-What happens when you reach 100k X/Y on the map? 1mil?
-I found out spawning many projectiles at once makes you ghost. Whyzat? I thought that's only for bricks.
-Does using > instead of >= do anything besides change the operator type?
-What does if(!%var) do? I used it for a ServerCmd to show if it had the right number of arguments and it didn't work.
-How do i get the range and angle from/to two objects? I use a big complicated structure involving getPosition(), ifs, and a lot of subtraction.

-What's the best way to spawn a bot that Blockland treats like a player? Testing purposes.
--If possible, include a way to give it a client and make a new clientobject.
-Is there a way to tumble a player without actually tumbling the player? (Set aim)
-Is there a way to switch the controlobject of two players/vehicles/etc? I've tried and it crashes everyone.

#1: http://forum.blockland.us/index.php?topic=162665.msg3986250#msg3986250

#2: This is a "Bitwise XOR", this is straight from the TAG: "Example: $a ^ $b, Explanation: composite of elements where bits in the same position are opposite. (i.e. 100b & 101b == 001b)"
#3: You'd still be working with 3D coordinates, therefore you wouldn't need to convert them into 2D coordinates (which is impossible because 3D has three axises and 2D has two axises).
#4: You are probably using the first function incorrectly, while the second one is editing the players position, not setting it.
#5: Nothing, the terrain just repeats. If you are on Slate then the ground will be "no-collide" and you'll fall in water but that is it.
#6: I assume your game needs to "render" those projectiles putting you into a ghosting state.
#7: Nope.
#8: If %var is equal to 0 then run what ever is in the if statement. If you didn't have the '!' in front of it, then it would be if %var is equal to 1 then run whatever is in the if statement.
#9: If your function works, use it.

#3: But how do I display a crosshair on a 2D GUI which seems like it's above the player in the 3D game?
#8: What i meant is:
function servercmdlolblargh(%c, %a, %b) {
if(!%b) { //asdf
//%b was not defined, so they must have thought a was b.
return;
}
dostuff(%a, %b);
}

%b always registers as %a in this case, making //asdf always trigger.

#9: It's huge. And messy. And i really think there's a better method.

EDIT: #1: Idungetit.

#3: If you're trying to do it client-sided, you'll need to spawn client-sided bots are the players and spawn or display images above them. It's very inefficient and does not work properly without a powerful machine.
#8: if(%b $= ""), if the variable was not defined then it should come out as null, in which case you would check to see if it's string equals null.
#9: I'll see if I can get a clean one working or find a clean one.

EDIT: To explain #1:
$remapDivision[$remapCount] = "KEYBINDCATEGORYNAME"; This will put your keybind under CATEGORYNAME in the menu.
$remapName[$remapCount] = "KEYBINDNAME"; This is the actual name of the keybind in the menu.
$remapCmd[$remapCount] = "FUNCTIONNAMEHERE"; This will be the function that is called when the key is pressed.

Oh, and

#1: I need it to be for any key, not just a keybinded key
