[Question] How to use the drawDebugSphere() function

[tangowrangler]

Have been trying to use the drawDebugSphere() function to draw a sphere without any success.

 

    local sp = Sphere(spcent,sprad)
    drawDebugSphere(sp, ColorRGB(1,0,0))

I tried to found some info and that is what I found:

 

You can look at dev's 'examples' in the following files:

data\scripts.old\entity\ai\mine.lua - line 141-147

data\scripts.old\entity\ai\salvage.lua - line 148-154

data\scripts.old\lib\entitydbg.lua - line 304-322

 

They're very similar though.

I suppose you should use this draw function inside of one of the following functions:

updateClient()

onPreRenderHud() - ClientSector Callbacks

onPostRenderHud() - ClientSector Callbacks

Thanks for looking through it. I saw those examples but i messed that they need to be inside updateClient(). I tried the following but sadly that didnt work too....

 

 

function updateClient(timeStep)
    mycraft = Entity(Player().craftIndex)
    -- sp = Sphere(vec3(1000,0,0),4799)
   if valid(mycraft) then
        print("valid")
        drawDebugSphere(mycraft:getBoundingSphere(), ColorRGB(1, 0, 0))
    end
end

 

 

The only example of the Render callbacks i found were using the UIRenderer() object. Still i tried with the following without success

 

function update(timeStep)
    if onClient() then
        Player():registerCallback("onPreRenderHud", "onPreRenderHud")
    end
end

function onPreRenderHud()
    mycraft = Entity(Player().craftIndex)
   if valid(mycraft) then
        print("valid")
        drawDebugSphere(mycraft:getBoundingSphere(), ColorRGB(1, 0, 0))
    end
end

 

I am trying to slash around the need to use a debugsphere. It is being very inconvenient though. I need it cause i am trying to implement an object detection radar thingy for path planning in a sector. first i was using a sphere to get entities. than i kinda figured i can just iterate over all the entities in a sector. the get getEntitiesByLocation is faster than getting all entities; however, if u have relatively big spheres, the performances are comparable. I still  have to test it out in an asteroid field, that may explode the algorithm iterating over all entities.

since its called drawDebugSphere, i suppose you wont see the sphere until some debug option is enabled (maybe its the "DebugScript" key binding? see game options for it).

I use other draw functions like drawText and they work fine in updateClient()and onPreRenderHud()!
