WHILE and WHILE TRUE statements

Hello, today i will explain "WHILE" statement

for "WHILE TRUE" i think it means while everything is = 1 = true ( we learned 1 means true , 0 means false)then run the script.

here is our simple script:

:start
wait 0
WHILE TRUE  // in capital or small letters (it doesn't matter)
    wait 0 // after every "WHILE" we need "wait 0" to avoid crashing
    if
  0AB0:   key_pressed 49 //1
    then  //every "then" needs "end" remember?
        0AD1: show_formatted_text_highpriority "YOU PRESSED 1" time 1000
    end  //this end is for "then" statement
END //this big "END" is for "WHILE" , so "while" get closed,, every while needs closer which is "end" 
// we don't need to use big END because end = END , so capitals doesn't matter but we use END with capital so we can read the script better (so we can notice that this end belongs to WHILE)
jump @start

for me i don't see a very big use for while true , but it may be handful with commands (http://ugbase.eu/tutorials/)read-commands-and-do-something-about-tut-open-source-codes/) so if we used while true means (and for example) if 31@ == 1 but even with that we don't really need it we can always replace it by if statement



but while true is useful in loops while like 21@ = 1

:first
wait 0  
if and
056D:   actor $PLAYER_ACTOR defined
//0AB0:   key_pressed 71  //g 
//0AB0:   key_pressed 72  //h
then
0B12: 21@ = 21@ XOR 1 //this will disable and enable with the same key
if
21@ == 1 // ENABLE IT   
then
WHILE TRUE //here under while true will loop until 21@ = 0 
wait 0
//do codes here 

//...etc

---

but now for the big thing and the best use of while statement

the following script is new for you , the idea of it , is recovering health while you are holding key 1

so this is our script:

{$CLEO}

0000: NOP

:START //our label
wait 0  
if  // we need this to run when we are alive only 
0184:   actor $PLAYER_ACTOR health <> 0  // "<>" means not equal , 0 means actor health and 0 = dead , the normal full health is 100 in most of servers
jf  [member=5120]Error[/member] // if actor is dead then jump at ERROR label
   WHILE 0AB0: key_pressed 49 // key 1 // will be explained below don't worry
   wait 0  //we add this to avoid crashing
 0851: set_actor $PLAYER_ACTOR decrease_health_by -2 affect_armour 0 // decrease by -2 = increase by 2 , it is math , decrease means negative , and negative negative 2 means positive 2
 0ACD: show_text_highpriority "Recovering 2H/ONHOLD" time 1500  
 END // to close WHILE statement
jump @START //jump to the label to loop again

:ERROR //our error label
wait 0
 0ACD: show_text_highpriority "You're DEAD ...!" time 1500 // this will get printed when you die
jump @START  // after display "You're DEAD" massage it will go to start label to loop again

so now "while" means while key 1 pressed run the  script

we use while in our life , and it is same here

so while key  1 pressed = while we are holding key 1 run the script

this is what while means.
so while this condition is true  do the following

and after every while we need wait 0

and we need the closer end just like then

this is  while code:

WHILE "CONDITION IS TRUE" 
wait 0
//do something here to get run while the condition is true

end

one thing more is if we want while not this condition is true
we use :

WHILE NOT 0184:   actor $PLAYER_ACTOR health = 0 //this means  actor health <> 0
wait 0
//do something here 

end

and congratulations you just made a health generator hack

Re: 9) WHILE and WHILE TRUE statement -TUT

but what if i want it to add 2 hp every 2seconds while im holding it? what should i do , and btw , we could just use key_down , instead of while

Re: 9) WHILE and WHILE TRUE statement -TUT

but what if i want it to add 2 hp every 2seconds while im holding it? what should i do , and btw , we could just use key_down , instead of while

WHILE 0AB0: key_pressed 49 // key 1 
wait 2000 // means 2 seconds
 0851: set_actor $PLAYER_ACTOR decrease_health_by -2 affect_armour 0 
 0ACD: show_text_highpriority "Recovering 2H/ONHOLD" time 1500  
end

key_down 49 = 0AB0: key_pressed 49

key_down doesn't mean while , but in some cases it means if you hold the key down , but you need while with it,but generally depends on how u  use it ,you can put key_down in repeat and say until not key_down(until key_up)
So this means while you are holding the key down then repeat , but if u are not holding the key the loop will end
