Toolbar icons:
Draw a pixel, or a free hand line, with the current height.
Escavate the terrain (new height=terrain height-current height). In case the new height is smaller than 0, then new height = 0
Elevate the terrain (new height=terrain height+selected height). In case the new height is bigger than 255, then new height = 255
Peek the terrain height (like the eyedrop, in graphic programs)
Select an area. Left click, after an area is selected will deselect it.
Important: When an area is selected, the following tools will operate ONLY in that area, not on the entire map: Smooth, Rise, Sink, Save and New terrain. New terrain, however, will act different: It will set the entire selected area to the current height
Replace the terrain height pointed by the mouse, with some other heights (see bellow). Right click on that icon, and it will bring up the tolerance mode/value. Basically, + tolerance means: "replace all the heights equal or greater than (the terrain height + tolerance value) with the current height. - and +/- tolerance modes are similar. Replace mode means:
= Just replace that height with the selected height.
- Substract from the old height, the current height.
+ Add to the old height, the current height.
The solid mode means "use the selected height", while pattern mode means using a selected pattern.
It is hard to explain, really, just experiment and see for yourself :)
Global Replace is very similar with the Replace tool, only that it will affect the ENTIRE terrain, instead of only the neighbour heigts that match the tollerance limit. Right click on that icon, and it will bring up the tolerance mode/value.
Flood an area with the current height, until it finds the terrain height again. Basically, if you draw a circle/rectangle, with the height of 10, and then you flood it's interior, with height 10, it will fill that rectangle with height 10. However, if you try to fill it with height 11, it will most likely ruin your entire terrain, trying to flood all the map. Just experiment with it.
Zoom in the terrain. There are 16 levels of zoom (100%-1600%). Note that you have to click on an area you want to zoom. Right click on it and it will zoom out.
Place object on/in/over the terrain.
Right click on it to get the options menu. Basically, there are 3 modes: Place, increase and decrease
Place means it will just put that object OVER the existing heights.
Increase means that the existing terrain will be increased with the height of the coresponding heights from that object.
Decrease means the same as increase, only that the terrain will be decreased.
I am not good at explaining things, so just play with the options, and you will see what they do.
When you are using an object (dragging it with the mouse), if you right click the mouse, the object will dissapear, and the current tool will be the pen (put height). So, next time you want to use the ojbect tool, you will have to load another object.
Smooth the entire terrain (averaging the heights). The more you use it, the flatter the terrain becomes.
Rise the entire terrain with the current height.
Sink the entire terrain with the current height.
Rotate or flip the terrain.
New terrain. Choose a x/y size bigger than 63 pixels, and smaller than 10000 pixels, and a background height, from 0 to 255. Note: It won't prompt you for a confirmation, so, unless you saved the previous terrain, that is lost.
Generate the relief. Note that, unless you check the option: "Overwrite terrain", it will only generate a new terrain on the black (0) heights, leaving the others unaffected.
Load a hmp or bmp file. Warning: there is no confirmation, so you will loose the old terrain, unless you saved it.
Save the current terrain into a hmp or bmp file.
Ctrl+z: Undo.
Tab: Switch between top down view and some sort of pseudo isometric view.
Caps Look pressed: The current cursor will change it's shape into a target, to have more control over the exact spot it will point.
Arrows move you on the map.
Right click on the terrain opens the "View menu", where you can select if you want to see the status bar, the toolbar, the minimap, and various grid sizes.
Right click nn the minimap, status bar, and tool bar (except on the toolbar's icons that do something when you right click on them) allow you to move them.
Enter, in a menu, means "Ok", ESC or right click means "Cancel".
