Returns

A string, else an empty string

Todo

this should not work very well, because too much va are used then we should locally cache values, or manage a temporary string structure

Todo

should we add a delta?

UI_ParseValueExpression()

uiAction_t * UI_ParseValueExpression ( const char ** text )

static

Read a value from the stream and init an action with it.

Returns

An initialized action else nullptr

Todo

when it is possible, we must check range of param id

Todo

We MUST remove the OLD code as fast as possible

Todo

use a better check - e.g. Com_ParseValue with V_INT or V_FLOAT
