Animation Based on Actor movement

[shadowburn]

Hi,

This may be related to Parent child relationship, however maybe not. How can I take 2 alternate backgrounds using transparency and make them move in the opposite direction when moving a centered character on the screen.

For instance, the infinite x background1 moves left once the character gets 20 pixels from the right side, and while its moving, the infinite x background 2 moves right once background1 starts moving left?

maybe in draw actor:

Code: Select all

x=center.x/20;

[shadowburn]

Get an error. x=center.x/20;


Illegal Structure Operation.

As rediculous as this was, I coded the actor animations all up to work now. Though thier may have been some hidden settings somewhere I havent found or maybe im blind and just missing, im sure it might have simplified tha matter abit more. I really can say that I do enjoy the power of the scripting language though. It has greatly opened up some flexibility in me doing this with the actor entites. I will have to open up another post on a new question and issue though. Thanks for the earlier reply.

you need to have a center actor that follows the player and the screen is parented to

maybe in draw actor:

Code: Select all

x=center.x/20;

You cannot safely do this because x may equal zero, which may not be divided.

Here is a work around. Use multiplication.

Code: Select all

x=center.x*0.05;


or slightly more obfuscated..

Code: Select all

x=center.x*1/20;


but thats going to be messy. Trust me.

or maybe

Code: Select all

x=center.x/20;
if(center.x==0)
{
center.x+=1;
}

or maybe

Code: Select all

x=center.x/20;
if(center.x==0)
{
center.x+=1;
}

That wont work because it is still dividing it by zero.
Try:

Code: Select all

if (center.x != 0)
{
    x = center.x/20;
}
else
{
    x = 0;
}

But I think

Code: Select all

x = center.x * .05;

is simpler

I just relized - this shouldn't be a problem because it is 0 divided by 20, which will be 0. It is when you have something divided by zero that you get the problem:

Code: Select all

x = 20/center.x;

could produce problems.
