onmapsingleclick command
for command enter what you want to occur, like onmapsingleclick exec "myscript.sqs"
for the buttons you mention, I think you mean params in the description.ext file. You need to define in the .ext what you want, then use a method to detect what the param is, such as a trigger,or the init.sqs. excerpt from a description.ext:
titleParam1 = "First choice item";
valuesParam1[] ={10,20,30,40,50,60,70,80,90,100};
defValueParam1 = 50;
textsParam1[] = {"10","20","30","40","50","60","70","80","90","100"};
titleParam2 = "second choice item";
valuesParam2[] = {1,2};
defValueParam2 = 1;
textsParam2[] = {"This","That"};
then in the init.sqs :
?param1==10:do this
?param1==20:do this other
?param1==30 and param2==1:do this thing and that other thing
hope this helps, and Dude, no need to apologize for your English....We can figure it, and I'm sure your English is better than most of our <<insert another language here>>
