A method for interacting with items on tables.

[Brainfree]

Hello,

 

Being that the models for items that are elevated are broken(there heights are wrong), I have come up with a method to advert this pesky problem, it simply builds a Prism around were the model should be, and collides its corner vertices to derive it's midpoint, which in most cases, is were exactly the models center point is. Cool stuff.

 

Example:

 

 

 

 

And the src code: 

package rdpv2;

import org.osbot.script.Script;
import org.osbot.script.ScriptManifest;
import org.osbot.script.rs2.utility.Utilities;

import java.awt.*;

@ScriptManifest(
        author = "Brainfree",
        version = 1.00,
        info = "Generates a point of elevation were a item on table should be, roughly",
        name = "Elevated Point Grabber"
)
public class TableGrabbing extends Script {

    public Point[] getLid(int x, int y, int height, double compression) {
        Point A = getScreenPoint(x, y, 0, 0, height);
        if (A.x == -1) return null;
        Point B = getScreenPoint(x, y, 0, 1, height);
        if (B.x == -1) return null;
        Point C = getScreenPoint(x, y, 1, 1, height);
        if (C.x == -1) return null;
        Point D = getScreenPoint(x, y, 1, 0, height);
        if (D.x == -1) return null;

        Point c = getInterceptionPoint(A.x, A.y, C.x, C.y, B.x, B.y, D.x, D.y);

        Point Ac = getPointOnLineAtDistance(A.x, A.y, c.x, c.y, compression);
        Point Bc = getPointOnLineAtDistance(B.x, B.y, c.x, c.y, compression);
        Point Cc = getPointOnLineAtDistance(C.x, C.y, c.x, c.y, compression);
        Point Dc = getPointOnLineAtDistance(D.x, D.y, c.x, c.y, compression);

        return new Point[]{Ac, Bc, Cc, Dc};
    }

    private Point getScreenPoint(int x, int y, int sx, int sy, int height) {
        return Utilities.getScreenCoordinates(bot,
                (x - client.getMapBaseX() + sx) << 7,
                (y - client.getMapBaseY() + sy) << 7, height);

        if (dot == 0) new Point(-1, -1);
        double X = ((x3 - x4) * (x1 * y2 - y1 * x2) - (x1 - x2) * (x3 * y4 - y3 * x4)) / dot;

Hope you can find great use of it.

Again, helpful code by you!! thank you!

[Rare]

Very nice work! This should help with some things. +1

 

Even though I don't script, I know this is big news.

I too don't script, but this is nice. Now we need a method for agility objects, because as far as I'm concerned, I'm almost positive agility objects aren't recognized.
