Send vector as on rez parameter

Created by Moonbuggy

Send vector as on_rez parameter

this script is to demonstrate how a vector could be sent to a rezzed object without using the listen event, sending it throught the start parameter in the llRezObject() function. There are two parts, the decoder that would be in the rezzed object to convert the start_parameter back to a vector the other part(s) is the encoder there are two encoders one to send a float vector eg <1.34,4.87,9.96> and one to send a integer vector eg <13,4,999>

Limitations

-- using the float encoder the maximum value that can be sent is 9.99

-- using the float encoder it is only accurate to 2 decimal places

-- using the integer encoder the maximum value that can be sent is 999

-- one big limitation at the moment is that only posative values can be sent
