DRAW Tool - Change a drawing/object with script ?

Kanelbolle · March 13, 2022

Hi,

anyone know if it is possible to example change the color of a "Polygon" that was made in the Draw tool (ME) with a script in mission ?

Can't find any documentation on this.

For what I know, you can only change parameters (with SetMarkup... functions) of script created markup ( DCS func markupToAll - DCS World Wiki - Hoggitworld.com ).

Right now they are two very different systems in several respects. You can't modify drawings from the editor via scripting, but you have access to their information. However the scripting engine doesn't have the same parameters as what is available in the editor. The two main ones being that line types are not the same and line thickness is not available in scripting. There are several other differences in the form of format, but those can be worked around. Namely:

Scripting color format is {r, g, b, a} in values 0 to 1 while editor is in hex
Points for drawings are stored relative to the first point with a mapX and mapY value defining the offset of that first point from map origin
Angle of a drawing is often its own value, so similar to mapX and mapY it will offset any points based on that value.
Oval and rectangle in drawings are defined as mathematical shapes. In other words a rectangle is height and width instead of being 4 points.
Arrow in the editor is a set of points making up a polygon while the scripting arrow is just between two points.

Easiest would be to use the editor to get the drawing information but actually add the shape via scripting, then changing it however you see fit via scripting again. Might even be easier to use a group's route to define the points and just call trigger.action.markupToAll with the valid parameters.

Thx both for pointing me in the right direction.

Haven't done much scripting the last year, so it's like starting from scratch..

I just made a coalition colored circle at every airfield with trigger.action.circleToAll

and used trigger.action.setMarkupColor to change it when the airfield got captured

Hi,

for others who wonder how, here is an example on how to draw a circle at an airbase and change the color.

Se miz file attached!

Draws a blue circle at the first airbase and changes the color to red after 10 seconds. (After the ring is drawn you need to move or zoom the map for it to show. Same when color change)

I can't get this to work at multiple air fields. I want to start with all fields as neutral in a white color and then change to the color of the corresponding coalition. I have made this happen at one field and can't get any color to show up at other fields. Here is my miz file for review.

You have to make sure the markId is unique when you create it. The second input value is used as the id, and you have it being the same for both. You can use the mist.marker.add function to create it if you don't want to have to manage it yourself.

 local ref = trigger.misc.getZone("Novo")
 trigger.action.circleToAll(-1 , 1, ref.point , ref.radius , {1, 1, 1, 1} , {0, 0, 0, .2} , 1 , true)


local ref = trigger.misc.getZone("Krymsk")
 trigger.action.circleToAll(-1 , 1, ref.point , ref.radius , {1, 1, 1, 1} , {0, 0, 0, .2} , 1 , true)

You could pretty easily use world.getAirbases and the base capture event to draw the circles as needed.

Would you be willing to post an example script? Does this function constantly monitor airbase status and change the colors accordingly?

No, you'd have to do that in scripting, and then post one of those actions depending on the result. I think an 'example' would basically be writing it for you.

Take a look at this: https://wiki.hoggitworld.com/view/DCS_func_addEventHandler

Can see if i can get one of my scripts cleaned up to post this weekend

Kanelbolle · March 15, 2024

Here is an example that does the following:

1. Checks all airfields what coalition it is

2. Draws a circle at the airbase according to the coalition color

3. Changes the color if it changes coalition between Blue and Red.

It does not, change if the airfields go Natural after it has been captured. You need a scheduled function to check this in a loop.

Added a example mission and the script.

Here is it raw. It's messy and old, but it an working example.

ebc = ebc or {} -- do not remove



function ebc.loadStartingBases()

	local baseCheckLoadeed = world.getAirbases()
	local myBaseLoadedTbl = {}
	
	for i = 1, #baseCheckLoadeed do
		   local infoLoaded = {}
		   infoLoaded.id = Airbase.getID(baseCheckLoadeed[i])
		   infoLoaded.desc = Airbase.getDesc(baseCheckLoadeed[i])
		   infoLoaded.point = Airbase.getPoint(baseCheckLoadeed[i])
		   infoLoaded.callsign = Airbase.getCallsign(baseCheckLoadeed[i])
		   infoLoaded.afcoa =  Airbase.getCoalition(baseCheckLoadeed[i])
		   infoLoaded.afbase = baseCheckLoadeed[i]
		  
		   
		   
		   if (Object.getCategory(baseCheckLoadeed[i]) == 4) and (infoLoaded.desc.category == 0 )  then
				
				-- Creates circle on map with same id as Airfiled ID (If you have other drawings on map, you should change what id the drawing gets
				if (infoLoaded.afcoa == 0 ) then
					trigger.action.circleToAll(-1 , infoLoaded.id , infoLoaded.point , 6000 , {1,1,1,1} , {0,0,0,0} , 5)

					-- RED AIRBASE
					trigger.action.circleToAll(-1 , infoLoaded.id , infoLoaded.point , 6000 , {1,0,0,1} , {0,0,0,0} , 5)

@Kanelbolle does your script also work with FARPs or only with fixed airbases on the map?

Not as it it is above, but it is a easy addition to add.

You just need to include the FARP category in the function ebc.loadStartingBases() :

infoLoaded.desc.category == 1

and in the event handler:

CapPlaceDesc.category == 1

Blackbahia · August 4, 2024

@Kanelbolle I couldn't manage that. I tried several times, but I think I always destroyed the script. I just don't know enough about scripting....

Here is a version with FARPS.

Just need a OR when checking the category.

Blackbahia · August 4, 2024

Thanks a lot, now it works!

I even managed to get the fill colour to be in a circle and change on capture! The trigger action "setMarkupColorFill" is necessary for this.

btw:
It only works with a FARP if "FARP" or "Invisble FARP" is selected. "Helipad single" and "PAD single" do not work. But the professionals here probably already know that!

Kanelbolle · August 8, 2024

Here is an example that includes single pad, it had category 2.

Is there a way to get the missing pieces implemented in the API? Are they going to add them? Line Style and Line Thickness are very important parts of the draw tool, that 1px line is basically invisible.
