You can emit from a clientResource to this resource with:
alt.on('PlacingModule:setObject', (object) => { showAlphaObject(object); });
So you can start placing an object in front of your player.
With the ARROW-Keys you can change the position and the rotation of the object you want to place. (normal position depends on your player rotation) With SHIFT-Key you can toggle the "alphaMode". So you can change the alpha-value of the object with the ARROW-Up and ARROW-Down key. If you dont want to place the object you can press SPACE and its canceled.
