Draw a 30* Cone Pointer - Looking for some help.

[ShotGun Jolly]

Guys.. I can really use the help with some XML coding for my Back Crusade ruleset.. I really need to get that 30* cone (pointer) to show up. But I can not get it to appear like it should...

I have followed the excellent instructions from Dulux-Oz in his tutorial; on how to do it. But I can not figure out why I can not get it to appear when I draw it on the map. I can get everything else to work, it shows range, the two points when you draw it and rotate it, but not the actual cone!

Anyone willing to try and help me figure it out???? Please?

Trust me, its not for lack of trying.. but there is something I am missing and I can not get it to work.

Ok..

Here is the problem that I can not solve..

I have added my custom cone to the radial menu, I can select it and I can draw it. In the below picture, you can see all of the other pointers which I can draw, (Circle, 45* Cone, and Line) Now, look at my mouse, where my mouse is currently resting, you can see one of two small squares.. this is my 30* which I drew. As you can see, there is no outline, just the start and finish points. And that only appears when I mouse over it.

Here is the campaign_Images.XML which I needed to edit to allow the pointers to show up.

<imagecontrol name="image">
			<script file="My_Cone.lua" />
        <pointertypes>
				<arrow>
			<icon>pointer</icon>
			<label>Draw Arrow</label>
		</arrow>
				<circle>
			<icon>pointer_circle</icon>
			<label>Draw Circle</label>
		</circle>
		<cone>
			<icon>pointer_cone</icon>
			<label>Draw Cone</label>
		</cone>
		<custom name="30ConePointer">
			<icon>pointer_cone</icon>
			<label>Draw a 30-Degree Cone</label>
		</custom>
	</pointertypes>

And here is the My_Cone.lua which I had to make so the above code could link to it.

function onBuildCustomPointer(nStartXCoord,nStartYCoord,nEndXCoord,nEndYCoord,sPointerType)
	local nLength = math.sqrt((nEndXCoord-nStartXCoord)^2+(nEndYCoord-nStartYCoord)^2);
	if nLength == 0 then
		return
	end
	local aShapeCurves = {};
	local aDistLabelPosition = {25,25};
	local bDrawArrow = false;
	local nAngleRadians = math.atan2(nEndXCoord-nStartXCoord,nStartYCoord-nEndYCoord);
-- Call the relevant Pointer Definition Function
	if sPointerType == "30ConePointer" then
		fpConePointer(aShapeCurves,nLength,30);
	end
-- Rotate and Position the Pointer
	for nIndex,aCurve in ipairs(aShapeCurves) do
		for nPointIndex,aPoint in ipairs(aCurve) do
			local nXCoord = aPoint[1]*math.cos(nAngleRadians)-aPoint[2]*math.sin(nAngleRadians)+nStartXCoord;
			local nYCoord = aPoint[1]*math.sin(nAngleRadians)+aPoint[2]*math.cos(nAngleRadians)+nStartYCoord;
			aCurve[nPointIndex] = {nXCoord,nYCoord};
		end
	end
	return aShapeCurves,aDistLabelPosition,bDrawArrow;
end

What am I doing wrong which causes my custom cone not to appear?

[darrenan]

I know absolutely nothing about the custom drawing stuff, so this may be a total stab in the dark, but could it be the line "local bDrawArrow=false" ? Should that be set to true somewhere?

EDIT: Ignore previous info in this post...

I take it you're trying to do something along the lines of this post: https://www.fantasygrounds.com/forum...ustom-Pointers

If so, this is suggesting that you need to subtract a centerx value from aPoint[1] and subtract a centery value from aPoint[2] in the calculations.

[ShotGun Jolly]

Tried both suggestions, even before Trenloe changed his first suggestion.. ;-)

Neither made any change at all, no matter what

when you get this working - could I make a suggestion/request? great! thanks could you package the pointer up as a standalone extension too (if possible) so that people can learn from your learns or at least just reuse your damn pointer.

When I get this working, would you show me how to make said extension? As I have no idea how to do that.

Besides, with the collective power of the internet on our sides.. I am hoping to solve this, and world hunger in the next few days..

OK, first off you're missing a function - where in your code is the fpConePointer() function?

And, obviously, the functions called by fpConePointer()?


Secondly, I don't think its going to be possible to put this into an Extension, mainly because you have to override other Pointer drawing code and therefore "stuff up" those other Pointers - mind you, if you prove me wrong then I'll take my hat off to you.

damned => its all in my Pointer Toolkit (on the Wiki and in the Thread on the Forums). Yes, its not the easiest thing in the world to do, but if you read through the doco (RTFM) you shouldn't have that much trouble - and you can always ask me (or others) questions.

I mean, that's why I made the damn thing

Just need to go through your final code and change the multiplication symbols x to * so that it works in FG!

Extension attached to do add a 30 degree cone to the CoreRPG ruleset. Thanks to dulux_oz for the code (even without the *s).
