How to...

Game.SetMouseCursor('GUI/mouse.bmp');
Game.SetMouseOffset(32,32);

MouseOffset is where the image hotspot is. Center of the image is considered as (0,0). For 64×64 image, topleft corner is (32,32)

Insert to an onRoomMouseDown event Actor.ClearWalkpoints();

function onRoom01MouseDown()
  Actor.ClearWalkpoints();
end

See list of virtual key codes

Now if you want to do something with space, use VK_SPACE

function SpaceKeyPress()
  Actor.Jump(1,2);
end
 
Game.Bind(VK_SPACE,'SpaceKeyPress');

If you want to use a key like 'W' that isn't found in the list, use Game.Ord('W') to change it to Virtual Key Code.

function FunctionToRun()
--something
end
 
Game.Bind(Game.Ord('W'),'FunctionToRun');

Dage doesn't have an easy function to do this, but you could do it with this little help from Lua:

function DumpVariables()
 Game.LOG('Dumping global variables');
 for n,v in pairs(_G) do -- Check all pairs from global tables
   Game.LOG(tostring(n).. ' - ' ..tostring(v)); -- LOG n - name and v - value
 end
 Game.LOG('Dumping done.');
end
 
DumpVariables(); -- Call every time you need to dump.
