merging of wall issues on 2d

[micreales]

Is there any way to prevent merging of wall ? like if you drag the wall on other wall it become one, that has a front and back edge ? Thanks

I was able to accomplish this via:

// src/model/corner.ts
// Disabled `this.mergeWithIntersected();`
private move(newX: number, newY: number) {
  this.x = newX;
  this.y = newY;
  // this.mergeWithIntersected(); -- Old behavior: Would merge while still dragging
  this.moved_callbacks.fire(this.x, this.y);

  this.wallStarts.forEach((wall) => {
    wall.fireMoved();
  });

  this.wallEnds.forEach((wall) => {
    wall.fireMoved();
  });
}

// src/floorplanner/floorplanner.ts
// Add `dragging` conditional + deletion
private mouseup() {
  this.mouseDown = false;

  // drawing
  if (this.mode == floorplannerModes.DRAW && !this.mouseMoved) {
    var corner = this.floorplan.newCorner(this.targetX, this.targetY);
    if (this.lastNode != null) {
      this.floorplan.newWall(this.lastNode, corner);
    }
    if (corner.mergeWithIntersected() && this.lastNode != null) {
      this.setMode(floorplannerModes.MOVE);
    }
    this.lastNode = corner;
  }

  // dragging
  if (this.mode == floorplannerModes.MOVE) {
    if (this.activeCorner) {
      this.activeCorner.mergeWithIntersected();
    } else if (this.activeWall) {
      this.activeWall.start.mergeWithIntersected();
      this.activeWall.end.mergeWithIntersected();
    }
  }
}

It did uncover bugs like not deleting corners properly which I'll be addressing in a PR
