Trigger_changevalue can perform arithmetic and logic operations on base-keyvalues of entities, as well as replace their private keyvalues. See trigger_copyvalue for a variant of this with more options. Supports custom keyvalues.
1 Keyvalues
Destination Entity : target
Name of the entity which's keyvalue is to changed. This can refer to more than one.
Destination Keyvalue : m_iszValueName
Name of the key which's value is to be changed.
Static source-value : m_iszNewValue
Value to be applied to the destination keyvalue.
Operation : m_iszValueType
Append spaces (for strings) : m_iAppendSpaces
When the destination keyvalue is a string, this specifies how many spaces to append after the operations. You'll usually want to use this with either the "Replace"- or "Append"-operation. This was implemented because Valve Hammer Editor omits any trailing spaces in keyvalues (but not leading ones).
Trigger after operation : message
Set entity/entities to be triggered after the trigger_changevalue has set the new keyvalue, by targetname as usual. This is very useful when you need a chain of operations to happen in a specific order and without any delay in between.
2 Flags
1 : Don't use X
When using vectors/arrays, this will ignore the first array. E.g., when setting render-color, specifying this flag would ignore the 'Red'-value.
2 : Don't use Y
When using vectors/arrays, this will ignore the second array. E.g., when setting angles, specifying this flag would ignore the 'Yaw'-value.
4 : Don't use Z
When using vectors/arrays, this will ignore the third array. E.g., when setting velocity, specifying this flag would ignore the vertical velocity.
32 : Invert target value
The destination keyvalue will be multiplied with minus one before proceeding.
64 : Invert source value
The source-value will be multiplied with minus one before proceeding; this change is only temporary and this keyvalue is rather useless, as you can always prepend a minus-sign to the static source-value.
3 Notes
Trigger_changevalue supports the use of "!activator" and "!caller" in the "Destination Entity"-field.Trying to write a vector to a float or integer will cause the vector's length to be written. This is in respect to any ignored dimensions as per spawnflags.
