[sharing] Small script to snap all objects to rounded coordinates in presentation mode

Here is a simple script that I have been meaning to write for a while and haven't found in the community yet.

When designing interfaces it can be very annoying if object positions have fractions, causing blurry anti-aliasing and almost-but-not-quite alignment. For some reason these fractions always seem to be unintentionally introduced after a while.

This script aligns all objects in presentation mode to rounded coordinates. Note that it only works when the patch you are aligning is in presentation mode and <pitfall alert!> if is used in patching mode, it will completely screw up your presentation object positions. This is due to a limitation in the max js API, we can't query the presentation coordinates of objects in patching mode and we also can't find out if a patcher is currently in presentation mode. But given these limitations , this can be a pretty handy script :)

Use it like this:

Save as 'objectsnapper.js':

function bang() {
    var obj = this.patcher.firstobject; 
    while(obj != null) {
        var r = obj.rect;
        var newR = [Math.round(r[0]), Math.round(r[1]), Math.round(r[2] - r[0]), Math.round(r[3] - r[1])];
        if (obj.understands("presentation_rect")) obj.message("presentation_rect", newR);
        post("Adjusting " + obj.maxclass + "\n");
        obj = obj.nextobject;
    }
}
