Once you've decided to clone actors rather than creating new ones, you will find loops to be invaluable.

Here is a basic loop structure:

Code: Select all

int i;
for(i=0; i<10; i++)
{
action here;
}

note that int declarations (int i;) must come at the very beginning of the script window.

Now if our action is:
CreateActor('block", "block1", "no parent", "no path", i*50, 0, true);

then the loop will run till its finished (i<10; so when i reaches 10, the loop stops).
And create an actor every 50 pixels.(50*i)

You can avoid having lots of clones in your editor mode by creating clones in game using loops.

Likewise, it makes sorting things much easier;

Code: Select all

int i;
for(i=0; i<10; i++)
{
if(blockcolor[i]>0){
do this;
}
}

This loop will check for any values in the array blockcolor[] and then you can use the output as you see fit.
You can also run that same loop, with the action
blockcolor[i]=0; and reset every cell in the array to 0.

Loops help you create, edit, and manage large groups of clones with ease.

Best of luck to you!

also if you go in file processing stuff, loop is a load off the back, it's fun creating a blank image like this:

Code: Select all

int i,j;
for(i=0;i<255;i++)
{
    for(j=0;j<255;j++)
    {
        red[i][j]=1;
        blue[i][j]=1;
        green[i][j]=1;
    }
}

It's easy to go into square and cubic (Or beyond) like data processing with loops

And dont forget to put the

Code: Select all

int i;   //or any other variables declaration

on the topmost of your code or else your srcipt would error...

You can nest these loops too, like this:

int i;
int j;
int k=ActorCount("enemy");
int l=ActorCount("missile");
for (i=0; i<k; i++){
if(healths[i]>0){
for (j=0; j<l; j++){
if missilex[j] > enemyx[i]){ //<-- notice how i'm still using i in the j loop, because the entire j loop
//is inside one instance of the i loop.
target[j]=i; //assign target i
j=l+1; //don't repeat the j loop after this
i=k+1; //don't repeat the i loop (target was found, and i has to be smaller
//than k for the loop to run).
} //end 'if missilex[j]' check
} //end j loop
} //end 'ifhealths[i]>0' check
} //end i loop

is there a way of a loop where it does the action after looping x amount of times? thanx in advance

yes, just increment a solid variable (not i or j).

int i;
for (i=0; i<10; i++){
if(i==9){
limit+=1;
if(limit>20){
do this;
}
}
}

Now the variable 'limit' is counting how many times the loop has been run.

excellent! Thanx
