How to hide, unhide, and set the text in a radio trigger.
--------------------------------------------------------------------------------
Question:
I want to get rid of the Radio Alpha text until a specific time in the mission. I have a car bomb script that is activated by the Radio Alpha trigger.
[t1] exec "carbomb.sqs"
So when the player selects RADIO ALPHA (which has the text of "Kill the Buggers!") the carbomb script activates.
Another trigger makes the script set to false - so the player cannot activate the script until it is set to true.
How do I hide the text from the Radio Menu until it is actually required?
Answer:
In the text part of the triger put:
null
When you want the text to appear, put:
1 setradiomsg "mytext" ("mytext" being the text that you want to appear)
When you want it to disapear again put:
1 setradiomsg "null"
See the setradiomsg command for more info on this.
