Replacement for Tile's "center point" in new OpenFl 4 Tileset?

[madneon]

Before OpenFl 4 there was a way of defining Tile’s central point of rotation, IIRC like so: Tileset.addTileRect(rectangle, point).

Now, it seems default rotation point is at 0,0.
As a workaround I’m shifting x,y using trigonometry:
var shift_x = width_half * cos - height_half * sin; var shift_y = width_half * sin + height_half * cos;

But I imagine calculating Sin and Cos on every angle change on every Tile is time-consuming.

Is there a faster way of doing this? Maybe utilizing Tile.matrix?

I did the same way.

But Restorer did with matrix if you are interested to check it out.

Proposal: Tilemap changes

That's what I do: // rotation : Float // scale : Float // positionX : Float // positionY : Float // pivotX : Float // pivotY : Float var mat = tile.matrix; mat.a = Math.cos(rotation) * scale; mat.c = Math.sin(rotation) * scale; mat.b = - mat.c; mat.d = mat.a; // set matrix before setting x and y, because they are setters, and they set // internal flag __transformDirty tile.x = positionX - pivotX * mat.a - pivotY * mat.c; tile.y = positionY - pivotX * mat.b - pivotY * mat.d; It seems t…

Any informations on supporting this in future OpenFL versions?

Thx for the hint @loudo, i ended up using matrices after all. Despite what @restorer posted some time ago, all seems to work fine with 4.4.1.
Matrices are amazing to work with, combining transformations is just plain pleasure
