If you want to send enemy squads over the map you need a walking grid.
To create a walking grid open the "Goto Grid Tool" in the "Windows" dropdown menu.
To visualize the grid activate the checkbox "View Goto Grid"
For placing a point click at "Place Point" and click with the lmb at your map. hold the lmb and click again and again to build a network of red lines. Don't make the net too small because it costs performance. If a squad walks along a path they will stop for a moment at each node. Important: If the distance of two connected nodes is too long, then the color changes from red to yellow!
At the picture below you will see a grid which is built automatically if you generate a skyrmish map with the "Random Generator".
To remove a node click at the "Remove Point" and then click at a node.
To delete a connection between two nodes click at the "Remove Connection" button.
To select and move one node click at the "Select" button and move it by holding the rmb.
Scripting: You can only use the grid goto commands, if you have created a goto grid!
