to launch projectile you need to add this command somewhere:

spawn_projectile(type,x,y,rot,range,id,livetime,state,imagerot)

where:
type = type of projectile from table,
x = x on map(in pixels),
y = y on map(in pixels),
rot = started rotation(may be as player rot),
range = range in CS2D's formula(NOTE!!! It's working like with cs2d's weapon range, for example m4's range is 300, by the formula in pixels is 300*3, so it will be 900) I also added to most grenades(You will see the first one have it) distance ~ like HEgrenade',
id = id of player who threw or 0,
livetime = time of it's living or 0. If it's 0 it would fly until reach floor/player/wall. If it's not 0 explosion turned after timer is gone. Depending on type' flying mode this timer working differently,
state = state of it's flying mode(you can see them below),
imagerot = rotation speed while flying.

NAME="Example",

Used for messages(not killicons).

IMAGE="gfx/sprites/flare3.bmp",

Used to find an image which will be used for this projectile.

SPEED=5,

value. The more number, the faster speed is. But keep in the mind. If speed is more than 16 it causes wall and player edge-skipping. If speed is more than 32 it causes wall and player skipping.

DISTANCE=125,

Cs2d's distance. This number will be automatically multipled by 3. Is like 125*3 = ~HEgrenade range in PIXELS.

STATIC=true/false,

Static image flying mode, if like with snowball if it's true(flying until reach player/wallcheck/distance)
and like normal hegrenade/flashbang etc(on pointer).

BOUNCE=true/false,

simple, does it bounce or not?

LIVETIME=1000,

this time started or going depending of flying mode(below below..)
In other words it's a time of it's living, working differently.

PLAYERSTOP=true/false,

Does it stop at player when meet him(like gut bomb/snowball) or not (like hegrenade/gas/fb etc)?

ROT=3,

rotation speed. More than 1 would rotate this image while it flying. 0 would not rotate but have it's started rotation.

MODE="mode",

available modes:
-flying:
This one would fly and die when reach it's range/player/wall.
-flying_eff:
This one working like molotov/gas. When it fell on the ground it would have effect as long as livetime.
-flying_time:
This one would fly as much as distance with no limit time, but LIVETIME would work like a timer, for example you threw a nade and it reach something(wall/player/range) then after "LIVETIME" action mode 2 will be launched(below)
-flying_p <- this one is not working, but added as experimental. I can't make HOMING missile with specific ANGLES.
But if you still using flying_p you can have additional things such as CHECKDIST=200, (distance of finding target), CHECKANGLE=50, (-50/2 and 50/2) <- this one would not work, because i can't add it :(
an effect while it's flying. It may be as "effect" and any other shits.
id = player source or 0
ex = x of projectile
ey = y of projectile
s = target
mode - if flying mode is only for MODE="flying_eff" or "flying_time". modes used to check what this projectile would do.
