"If and" statements

[kathryn]

Hello. I'm trying to figure out if AGS is capable of "if and" statements. I have read the help manual (accessed from within the software itself), and have searched this forum.

The title of one post appeared relevant (see http://www.adventuregamestudio.co.uk/yabb/index.php?topic=8270.0), but a moderator has moved the post, deleted the content and provided a link which is now dead.

A live link to some assistance on this issue would be much appreciated.

Thanks.

Sure it does. It doesn't have switch-case, but the "IF" feature is there since day one

This is from the built in AGS manual.

if, else statements

if ( expression ) {
statements1
}
[ else {
statements2
} ]
If expression is true, then statements1 are run.

If expression is not true, and there is an else clause present, then statements2 are run instead.

For example:


if (GetGlobalInt(5) == 10) {
  Display("Globalint 5 is 10.");
}
else {
  Display("Globalint 5 is not 10.");
}

In this example, the first message will be displayed if the return value from GetGlobalInt(5) is 10, and the second message will be displayed if it is not.
if statements can be nested inside else statements to produce an "else if" effect. For example:


if (GetGlobalInt(5) == 1) {
  Display("Globalint 5 is 1.");
}
else if (GetGlobalInt(5) == 2) {
  Display("Globalint 5 is 2.");
}
else {
  Display("Globalint 5 is not 1 or 2.");
}

So in fact the answer is "no". Based on the manual, then, AGS is only capable of "else if" statements.

Thanks.

Hehe - yeah I should have read your post properly.

[Khris]

If by "if and", you're talking about testing "if (condition1 and condition2)", then sure, that's perfectly possible.

Code: ags

  if (a == 3 && mouse.Mode == eModeInteract) {

Take a look at the operators section of the manual:

Thanks, Khris. Just found the operators section on the Wiki page.

Is there any way to search for operators (for example) in the manual? Most of my troubles stem from not being able to find what I'm looking for.

[Khris]

Searching for something else than plain text is hard or even impossible sometimes.
Best thing is to peruse the manual once.

I assume you're aware of the helpfile that comes with AGS?

I think you should search for "operators" on Index page of AGS manual.

Anyway, don't want to sound rude and all, but... heh, I always have uneasy feeling when people asking questions like "does AGS have <some ultra-basic-which-every-programming-language-has code feature here>".
I would be seriously terrified if AGS didn't have them.

I've mentioned this before, but I believe this is a sound suggestion since not every programming language is the same:
For the basic programmers who don't/didn't know that these are called Operators (including me when I started with AGS :), I would like to see 'or' and 'and' in the manual, which could then direct you to the Operators page.

Or maybe add "conditions" topic, which could be also part of "if/else" article.

Yeah, that's my first point of reference when I encounter problems or questions. Since the online manual and the AGS help file appear to be the same, in future I'll use Google to search the online manual instead. (For example, type site:http://www.adventuregamestudio.co.uk/manual along with my key words of interest.) I suspect many of the newbie "can I do this?" questions wouldn't be necessary if the help documentation were more accessible to text searches. (And more flexible searching; as Ryan Timothy pointed out, not everyone is experienced enough to know to search for "operators".)

Me too, but we're only asking these questions because we expect the AGS language to have such functionality, but can't find documentation about it. At least some of us know exactly what we're looking for, but can't find it with ease. After all, this is the Beginners' Technical Forum.
