Quest Expressions

Quest expressions start with "="

Only supported for rewards.

example:

 =2*@par

Syntax

 * @par -> dynamic parameter (see annex 1 below)
 * ?prop -> property from pcproperties
 * ?entname.prop -> property from some entity pcproperties
 * * -> multiply
 * + -> add
 * - -> substract
 * / -> divide
 * % -> modulo
 * ~ -> bitnot
 * ^ -> bitxor
 * == -> equality
 * != -> inequality
 * <= -> lesser or equal
 * >= -> greater or equal
 * < -> lesser
 * > -> greater
 * funcname(par1,par2...) -> run a function

values

 * false -> boolean false
 * true -> boolean true

functions

parameters inside [] are optional

 * pc([ent],name)
 * pctag([ent],name, tag)
 * param
 * property([pc],propid)
 * id
 * parid
 * actid
 * propid
 * rgb(r,g,b) -> color code
 * abs(number)
 * min(n1,n2) -> min
 * max(n1,n2) -> max
 * config
 * mousex() -> mousex
 * mousey() -> mousey
 * normalize(vector) --> normalized vector
 * bb_mousex
 * bb_mousey
 * cos(number) -> cos
 * sin(number)
 * tan(number)
 * acos(number)

 * intpol(a,b,c)
 * int(something)
 * float(something)
 * bool(something)
 * rand(number)
 * bb_testcollide
 * if(expr, trueexpr, falseexpr) 
 * entname() -> entity name
 * ent() -> entity, ent(entityname) -> entity
 * sound
 * sound_paused
 * strlen
 * strsub
 * stridx
 * scr_width()

 * readfile
 * writefile
 * getyrot(dx,dy) -> angle
 * vecx(vec) -> vec.x
 * vecy(vec) -> vec.y
 * vecz(vec) -> vec.z
 * colred(col) -> col.red
 * colgreen(col) -> col.red
 * colblue(col) -> col.red
 * getmsg(msg) -> translated message
 * key_node(sector,node,key,[value])
 * key_meshobj(meshobj,key,[value])
 * key_sector(sector,key,[value])
 * key_meshfact(meshfact,key,[value])
 * key_texture(texture,key,[value])

Examples

 * =if(mousex()<10,'left','right') <- returns left or right according to mousex position
 * =if(property(pc(tools.config.json),propid(index))==0,10,-1) <- returns 10 o -1 according to index property.
 * =property(pc(pc2d.billboard),propid(text)) <- returns the value of the "text" property from the "pc2d.billboard" pc in current entity.
 * =enemy+?i -> returns something like enemy13 (if i pcproperty was 13 at the moment)
 * =[1,2,3] -> returns a vector3 with contents x=1 y=2 z=3

Annex 1: Dynamic parameters

If you use @par (instead of the already existing $par notation) you can get dynamic parameters from triggers. As opposed to static ($par) parameters these parameters can change every time the reward is fired. Currently there are the following limitations:

 * @par notation does not work in triggers (that will stay).
 * @par notation does not work in sequences.

Dynamic parameters each trigger sends

 * message --> forwards all message parameters
 * inventory --> @child (name of added or removed entity)
 * meshsel --> @entity (name of the selected entity)
 * trigger --> @entity (name of the entity triggering)


Annex 2: Escape characters

 * some characters need to be escaped when they live in xml attributes:
   * < : "&#60;"
   * & : "&#38;"

example: 1<2 becomes 1&#60;2

Annex 3: unusable functions

functions which aren't useful due to some missing features from blxml

 * inventory_get
 * inventory_count
 * inventory_in
 * inventory_find
 * inventory_inname
 * inventory_findname
 * actionname{par1=XXX,par2=XXX,par3=XXX...}
