I'm trying to add a new tool to maptool (the line-of-sight/concealment tool I suggested here).

I have small set of data stored with the tool (the points clicked on, basically) and I want to clear them when the user chooses a new tool or loads a new map. Is there a method to override for this or something?

Also, since I'm posting I might as well ask - right now the lines my tool draws are only visible to the user. I'd like to add a button to reveal them to all players so that you can use the tool to show everyone that you have line of sight to settle arguments. The only way I can see to do this is to send a server "draw" command. Then to get rid of the diagram I'd need to draw over it with the same drawing set to erase. I haven't had time to test this yet - would that interfere with actual drawings done with the draw tool (ie. accidentally erase them if there's overlap)?

There's an "attachTo()" and "detachFrom()" method on the tools that you can override. They are called when a tool is selected or deselected respectively.

You'd have to create a mechanism to transfer the data through the server API, using drawings probably isn't the most efficient way. Take a look at the way the pointer works (holding SPACE on a map shows an arrow where you are pointing)

Thanks, that's very helpful!

Now here's hoping I can get this finished and distributed to my players before my game on Wednesday...

There's also a "resetTool()"

I'm starting on the "space bar reveals to all players" feature. I'm finding the keyboard handling is really unreliable. Half the time when I start the app, the space bar doesn't work at all (in this tool only) until I restart.

Here's the code so far (it just pops up a pointer at the moment):

Code: Select all

protected void hideLines() {
    MapTool.serverCommand().hidePointer(MapTool.getPlayer().getName());
    linesRevealed = false;    	
}
    
protected void revealLines() {
    Pointer pointer = new Pointer(renderer.getZone(), startPoint.x, startPoint.y, 0, Pointer.Type.THOUGHT_BUBBLE);
    MapTool.serverCommand().showPointer(MapTool.getPlayer().getName(), pointer);
    linesRevealed = true;
}

@Override
protected void installKeystrokes(Map<KeyStroke> actionMap) {
    super.installKeystrokes(actionMap);

    actionMap.put(KeyStroke.getKeyStroke(KeyEvent.VK_SPACE, 0, false), new AbstractAction() {
        public void actionPerformed(ActionEvent e) {
            if (linesRevealed) {
                hideLines();
            } else {
                revealLines();
            }
        }
    });
}

Any idea what could be wrong?
