Few Scripting Questions

[skatey]

Ok i started using ags 1 day ago and i have made alot of progress i know alot of the scripting (mainly to knowing C++, C, java, perl) so it was pretty easy but i have a few questions:

i have  a popup menu which shows when you right click the code shows its middle at the mouse:

example:

gMenu.X = mouse.x - gMenu.Width;
gMenu.Y = mouse.y - gMenu.Height;

or so i think that was it im not sure but anyway when it shows i make sure it dosent show off the screen like this:

exaple:

if(gMenu.X < 0){
   gMenu.X = 0;
}
else if(gMenu.X > game.room_width){
          gMenu.X = game.room_width - gMenu.Width;
}

if(gMenu.Y < 0){
   gMenu.Y = 0;
}
else if(gMenu.Y > game.room_height){
          gMenu.Y = game.room_height - gMenu.height;
}


but a problem occurs when you use scrolling menus it dosent work so is there another way to get this value i tried system.width and system.height but they didnt work.

I have a bar on my gui which has inventory (alternative for right click) show, and all the mouse modes but for some reason it isnt detecting the mouse presses i cannot give an example of my code because the chances are it wouldnt, i am just wondering if anyone has came across this problem in the past. Oh also i used the button event (Left Click = change mouse mode) but that didnt work.

I'll be thankful for any help, and if anyone needs any coding done for there game i will be happy to help.

I did a verb coin some time ago, and to stop it from going out of the screen I first calculated the position, according to the mouse co-ordinates, and then moved to GUI to position and turned it on. GUIs work on screen co-ordinates, not room, so you can just use 320 for width (if it's low res, 640 if it's hi res) and 200 or 240 for height.

Easy enough but how did you make sure gITEM.X + gITEM.Width isnt more than the screen ?

[Ishmael]

You mean how to stop it from going out of the right edge?

if (mouse.x > (system.width - gMenu.width/2))
Ã,  gMenu.x = (system.width - gMenu.width/2);

Haven't tested, but that ought to do it.

...so you can just use 320 for width (if it's low res, 640 if it's hi res) and 200 or 240 for height.

A bit of correction, horizontal screen res is still 320 when it's hi-res (it's 400 if you use 800x600 mode).

Rrrright, me not thinking again... : Sorry.

I tried that but for some strange reason would not work. So know any fixes ?

[Ishmael]

Try this simple change then...

if (mouse.x > (320 - gMenu.width/2))
  gMenu.x = (320 - gMenu.width/2);

[skatey]

haha you gave me the anwser not exactly the same but similar since i always use srolling screens *2 of my normal size so my 640 normal screen gets turned in 1280 i can just /2 and it works fine but then again this is only thoery lol i gotta get home and try this.

Try this simple change then...

if (mouse.x > (320 - gMenu.width/2))
gMenu.x = (320 - gMenu.width/2);

That will leave it half off the screen though, so you probably want:

if (mouse.x > (320 - gMenu.width))
gMenu.x = (320 - gMenu.width);

Doh >_< Yes, thankyou.

I haven't done any serious scripting in ages, my basic knowledge is beginning to rust, I think...
