A right-click box that appears when you click on a terrain piece or object
It's on my list.
Similar to LemEdit, it would have a "copy" and "delete" and "change terrain" function.
Copy = Ctrl + C (or main menu edit/copy)
Paste = Ctrl + V (or main menu edit/paste)
Delete = Delete
For changing the terrain I will add a keyboard shortcut for a direct popup. When you know the number of the object and you are working in the level-editor then you can type the number and press <enter>.
The number you type is in the statusbar.
So inserting any new terrain is 3 or 4 keyboard strokes: "Insert, 2, Return" and when youre doing a Marble Level you get the terrain triangle number 2.
Also, if you right click in the map where there's no terrain or objects or steel areas, you should have an "add terrain/object/steel" option.
On my list...
Precision keyboard control. Maybe use the arrows on the number-pad to move the terrain up or down one pixel per click? I find it a bit hard to place terrain precisely with this editor.
Dragging the terrains pixel-precise is not ok yet. When holding the Control key the arrow keys move the objects per pixel instead of 8 pixels.
A box which pops up when you want to add a new piece, similar to what you get when you click the "..." in the terrain inspector, that allows you to select which terrain piece you want to place before it is placed. I do not particularly like having to click "add piece" and then using the level inspector to change the terrain, because I am lazy.
I will add the pop-up it (optional I think).
Maybe try Lemmix's "number typing system" in combination with Copy/Paste. And Copy/Paste Special, which I think is very handy.
An option to place the terrain inspector and list and the level properties window underneath the level map instead in different windows.
Good idea I think. On the list...
I am currently working on 0.0.3 so the things you mentioned will not be in it yet. I will try to put them in 0.0.4
There are some hints on the Lemmix site about mouse/keyboard usage.
I saw some levelpacks you made (got them from the Garjen site).
Nice work, close to art
