MOD: nudge in Texture Coordinate Editor

[Andy]

Add cursor key control to move the selection inside the TCE.

This mod requires editing of internal AC3D script files. If this is done wrong, you could stop AC3D from working. We recommend this is tested on an alternate installation/copy of AC3D.

With a text editor, edit tcl/ac3duvedit.tcl
Go to near the end of the file and find these two lines:

    bind .uvedit s { set uvmode surface ; ac3d uv_selectmode 0 ; uv_do_sensitivity } 
    bind .uvedit v { set uvmode vertex; ac3d uv_selectmode 1 ; uv_do_sensitivity }

After these, insert this text:

    set nudge_dist 0.01
    bind .uvedit <Up> "ac3d uv_move_relative 0 $nudge_dist"
    bind .uvedit <Down> "ac3d uv_move_relative 0 -$nudge_dist"
    bind .uvedit <Left> "ac3d uv_move_relative -$nudge_dist 0"
    bind .uvedit <Right> "ac3d uv_move_relative $nudge_dist 0"

The value for 'nudge_dist' here (0.01) can be changed - this is the distance that the selection will move when one of the keyboard arrow keys is pressed.

I did as suggested, but I cant seem to get this to work

I'm using this modified code:

        set nudge_dist 0.001
	bind .uvedit <Up> "ac3d uv_move_relative 0 $nudge_dist"
	bind .uvedit <Down> "ac3d uv_move_relative 0 -$nudge_dist"
	bind .uvedit <Left> "ac3d uv_move_relative -$nudge_dist 0"
	bind .uvedit <Right> "ac3d uv_move_relative $nudge_dist 0"
	
	set nudge_far [expr $nudge_dist*10]
	bind .uvedit <Shift-Up> "ac3d uv_move_relative 0 $nudge_far"
	bind .uvedit <Shift-Down> "ac3d uv_move_relative 0 -$nudge_far"
	bind .uvedit <Shift-Left> "ac3d uv_move_relative -$nudge_far 0"
	bind .uvedit <Shift-Right> "ac3d uv_move_relative $nudge_far 0"
	
	set nudge_fine [expr $nudge_dist/10]
	bind .uvedit <Control-Up> "ac3d uv_move_relative 0 $nudge_fine"
	bind .uvedit <Control-Down> "ac3d uv_move_relative 0 -$nudge_fine"
	bind .uvedit <Control-Left> "ac3d uv_move_relative -$nudge_fine 0"
	bind .uvedit <Control-Right> "ac3d uv_move_relative $nudge_fine 0"

As in Andy's code above, the value for "nudge_dist" can be changed.
Using the arrow-keys together with the Shift-key moves the selection 10 times as much as defined for "nudge_dist".
Using the arrow-keys together with the Ctrl-key moves the selection a 10th of the defined value.

great stuff!

Great idea, one I've wished for for some time.

My only question is, what are the units for the nudge distance? Pixels? mm's? Or, can they be custom set?

This would be fractions of the texture size. 0.01 is 1/100 of the texture image height or width. The first key bindings were added into the defaults for AC3D 6.7. The control and shift bindings are 1/1000 and 1/10 of the texture image size.
