Hi all. I am making new game "engine" that will be realistic. It have real physics and so.

Question: I have a line make from 2 actors. (actor1 and actor2)
who dont know what I mean, here is the script:

Code: Select all

erase(0,0,0,1); //erase...
setpen(0,255,0,0,15); //pen color..

moveto(actor1.xscreen, actor1.yscreen); //draw line from actor1...
lineto(actor2.xscreen, actor2.yscreen); //..to actor2.. ;)


So, how to set distance between these 2 actors. I want it to be 200pixels. How to set it ?
For those who dont understand what I want.

what ever are the positions or actor1 and actor 2...

..the distance between them must be 200px!

explanation

Please help me if you can.

Thanks

Well, if you want the players to be always within 200 pixels of each other, they would always be within a given circle. It kind of depends on how you want to set their position, but here is an example.
Actor1 -> Draw Actor -> Script Editor

Code: Select all

double ang = degtorad(direction(x, y, Actor2.x, Actor2.y));
x= Actor2.x+cos(ang)*200;
y= Actor2.y-sin(ang)*200;

Yeah. Its setting the distance 200pixels. Thanks good. But I dont know why, the actor 1 apears first time UP and then DOWN the actor 2.

Hm. Well, its working but not good.

Is there way to make it like:

if(x<actor2.x+200) {make distance between them be 200px} or something like that.

Dont know. But thanks for helping me. Merry Christmas!

If you want it to be just when the distance is greater than 200, than you can use an if. But, there was a typo in my above post. Here's what it should have been.

Code: Select all

double ang = degtorad(direction(x, y, Actor2.x, Actor2.y));
x= Actor2.x-cos(ang)*200;
y= Actor2.y+sin(ang)*200;

With the if statement included would be this.

Code: Select all

if(distance(x,y,Actor2.x,Actor2.y)>200)
{
    double ang = degtorad(direction(x, y, Actor2.x, Actor2.y));
    x= Actor2.x-cos(ang)*200;
    y= Actor2.y+sin(ang)*200;
}
