'''END'''<br />
<br />
'''If''' statements are used to control the flow of your program by means of checking a condition.<br />
<br />
<pre><br />
if( <condition1> )<br />
// code1<br />
elseif( <condition2> )<br />
// code2<br />
else<br />
// code3<br />
end<br />
// code4<br />
</pre><br />
<br />
If at the time the program reaches this '''if'''-codeblock ''condition1'' is [[true]], then ''code1'' will be executed and then ''code4''.<br />
If ''condition1'' is [[false]], the program will go to the next '''elseif''' or and check if that is true or false: if ''condition2'' is true, ''code2'' and then ''code4'' is executed. If ''condition2'' is false, the program will check the next '''elseif''' and do the same thing over, until the program reaches the '''else''' or the '''end'''.<br />
If an '''else''' is present, the code in the '''else'''-block will thus be executed when all other conditions are false.<br />
<br />
== Example ==<br />
<br />
=== Execute function ===<br />
This is a little example of how to make a function perform a certain task depending on a command.<br />
<pre><br />
Function int execute(String command, int* params)<br />
Begin<br />
<br />
if( command == "SEND" )<br />
NET_Send(atoi(params[0]),params[1]);<br />
elseif( command == "RECV" )<br />
NET_Recv(atoi(params[0]));<br />
elseif( command == "INIT" )<br />
NET_Init(atoi(params[0]),atoi(params[1]),atoi(params[2]));<br />
elseif( command == "QUIT" )<br />
NET_Quit();<br />
else<br />
// error: command unknown<br />
return -1;<br />
end<br />
<br />
return 0;<br />
<br />
End<br />
</pre><br />
<br />
=== Movement ===<br />
Movement with '''If'''s.<br />
<pre><br />
Loop<br />
if(key(_up)) y-=5; end<br />
if(key(_down)) y+=5; end<br />
if(key(_left)) x-=5; end<br />
if(key(_right)) x+=5; end<br />
End<br />
</pre><br />
Of course, this is faster:<br />
<pre><br />
Loop<br />
y += 5 * (key(_down )-key(_up ));<br />
x += 5 * (key(_right)-key(_left));<br />
End<br />
</pre></div>Sandman
