Is it possible to script an object the randomly create a number, and then use that number to do something? ... For example, Using a timer event, every ten seconds an object will create one of four possible objects (powerups in this case) and the possibility of creating nothing too... does that make sense?

on a create actor event put this:

int n;
n=rand(100);
if (n==0){put code here that will exacute 1% of the time
}
if (n<=10 && n>0){put code here to exacute 10% of the time
}

Thanks a bunch! Exactly what I needed!

.. I originall put this script on a timer for a filled-region actor, and it didn't do anything... so I then moved it to the create-actor script (as instructed) amd still doesn't do anything... Did I do something wrong here?

int n;
n=rand(100);
if (n=0)
{
CreateActor("pu_1up", "pu_shield00000", "(none)", "(none)", 0, 0, false);
}
if (n<=50 && n>0)
{
CreateActor("pu_gun", "pu_gun00000", "(none)", "(none)", 0, 0, false);
}
if (n<=100 && n>50)
{
CreateActor("pu_shield", "pu_shield00000", "(none)", "(none)", 0, 0, false);;
}

n ==, not n =.

thanks Sgt Sparky,

Just to clarify,
in the if statement it should read n==0
when declaring what n is equal to you would use a single equals

note: I have edited my original code with this correction.

that is what I said. xD

Right you are.. should have caught that myself... .. speaking of random variables, what if I wanted my actor to move to a random location (within the view) on a keydown event?

events->add->keydown->whateverkey->

Code: Select all

xscreen = rand(view.width);
yscreen = rand(view.height);

maybe somethign like:

Code: Select all

x=rand(view.width)+view.x;
y=rand(view.height)+view.y;

Calculates a random number whithing the views size and add the position to it.

sparky was quicker then I D:

You guys are smarter then I know what to do with...

Code: Select all

switch( var holding a rand value)
{
    case 0:    createactor;
                 break;
    case 1:    createactor;
                 break;   
    case 2:    createactor;
    default : break;
}


Use as many cases as you like.

The break statements bails out from the test, otherwise it might ring true for several cases and execute their code. Default will run after all the others. Especially if you dont break before then. Note that I left a break out after the case 2, because the default handles in. I dont like redundancy.
