Also, a piece of unitialialized memory should now be fixed. there's a con_centertext cvar added an extra default particle texture. further dp protocol compatability stuff. EF_ADDATIVE works on models and supposedly sprites. will do sw sprites too at some point. Linux makefile needs work still. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@1017 fc73d0e0-1445-4013-8a0c-d673dee63da5

NPC chat:
|
|
The idea is that the server reads in a text file, calls qc functions as appropriate, and centerprints the result to the corresponding player.
|
|
All play is paused while the chat is in progress.
|
|
There are no guarentees that this is useful to anyone. If it does sound sorta what you want and would like a small change then just ask.
|
|
|
|
The options are specified with commas between. a number specifies a tag, anything else is assumed to be a statement/function,
|
|
which is carried out when the text is used (rather than when it is mearly an option).
|
|
statements can be functions, addition, multiplication, division, subtraction. Storing is also possible.
|
|
To store, you need to name a variable (which will be created when used). The variable must be a float.
|
|
Strings will work ONLY when specified without arithmatic, and ONLY in function calls.
|
|
You can call QC functions which accept entities on the condition that the entity accepted is the player entity that is being used for the menu.
|
|
If you want to keep track of the person you are chatting to, use an entity field for it.
|
|
To pass this entity, use the word 'ent', without quotes of any kind.
|
|
Do not use operators or calls within a function call. It's not that advanced. You can use operators on the condition that you use and name a temp.
|
|
|
|
|
|
|
|
|
|
|
|
Exmaple dialog script:
|
|
dialog/barry.dlg:
|
|
|
|
#tag/number, condition (float(entity ent) cond;), text, options.
|
|
#if options has a function, that is called. Multiple options/funcs can be done with commas. No options will terminate. If a reply has multiple options, a random (non function) is picked.
|
|
#no distinction between characture speech and player options.
|
|
#char statements ignore condition.
|
|
|
|
#the first entry point
