### Drawing a marker & Vehicle detection
|
|
|
|
Drawing markers in the map can be one of the best ways to indicate to the user that there is some form of interaction that they can do there.
|
|
|
|
Drawing a marker is fairly easy. Here is an example of how the bus route marker is drawn:
|
|
|
|
```Lua
|
|
local function createBusMarker(markerName)
|
|
local marker = createObject('TSStatic')
|
|
marker:setField('shapeName', 0, "art/shapes/interface/position_marker.dae")
|
|
marker:setPosition(vec3(0, 0, 0))
|
|
marker.scale = vec3(1, 1, 1)
|
|
marker:setField('rotation', 0, '1 0 0 0')
|
|
marker.useInstanceRenderData = true
|
|
marker:setField('instanceColor', 0, '1 1 1 0')
|
|
marker:setField('collisionType', 0, "Collision Mesh")
|
|
marker:setField('decalType', 0, "Collision Mesh")
|
|
marker:setField('playAmbient', 0, "1")
|
|
marker:setField('allowPlayerStep', 0, "1")
|
|
marker:setField('canSave', 0, "0")
|
|
marker:setField('canSaveDynamicFields', 0, "1")
|
|
marker:setField('renderNormals', 0, "0")
|
|
marker:setField('meshCulling', 0, "0")
|
|
marker:setField('originSort', 0, "0")
|
|
marker:setField('forceDetail', 0, "-1")
|
|
marker.canSave = false
|
|
marker:registerObject(markerName)
|
|
scenetree.MissionGroup:addObject(marker)
|
|
return marker
|
|
end
|
|
|
|
-- this can then be called in a loop to setup your markers.
|
|
-- NOTE: You should only do this once as part of your setup and not called on each frame.
|
|
if #markers == 0 then
|
|
for k,v in pairs(nameMarkers) do
|
|
local mk = scenetree.findObject(v)
|
|
if mk == nil then
|
|
log('I', logTag,'Creating marker '..tostring(v))
|
|
mk = createBusMarker(v)
|
|
ScenarioObjectsGroup:addObject(mk.obj)
|
|
end
|
|
table.insert(markers, mk)
|
|
end
|
|
end
|
|
```
|
|
|
|
Here is a custom marker example from [BeamNG-FuelStations](https://github.com/BeamMP/BeamNG-FuelStations/tree/master):
|
|
|
|
```Lua
|
|
local stations = [
|
|
{ "location": [ -778.813, 485.973, 23.46 ], "type":"gas" },
|
|
{ "location": [ 617.164, -192.107, 53.2 ], "type":"ev" },
|
|
]
|
|
|
|
local function IsEntityInsideArea(pos1, pos2, radius)
|
|
return pos1:distance(pos2) < radius
|
|
end
|
|
|
|
local onUpdate = function (dt)
|
|
for k, spot in pairs(stations) do -- loop through all spots on the current map
|
|
local bottomPos = vec3(spot.location[1], spot.location[2], spot.location[3])
|
|
local topPos = bottomPos + vec3(0,0,2) -- offset vec to get top position (2m tall)
|
|
|
|
local spotInRange = false -- is this spot in range? used for color
|
|
local spotCompatible = false -- is this spot compatible?
|
|
|
|
if activeVeh then -- we have a car and its ours (if in mp)
|
|
local vehPos = activeVeh:getPosition()
|
|
|
|
spotInRange = IsEntityInsideArea(vec3(vehPos.x, vehPos.y,vehPos.z), bottomPos, 1.5)
|
|
|
|
spotCompatible = activeFuelType == "any" or spot.type == "any" or activeFuelType == spot.type
|
|
end
|
|
|
|
local spotColor = (spotInRange and spotCompatible) and activeColorMap[spot.type] or inactiveColorMap[spot.type] or ColorF(1,1,1,0.5)
|
|
|
|
debugDrawer:drawCylinder(bottomPos:toPoint3F(), topPos:toPoint3F(), 1, spotColor) --bottom, top, radius, color
|
|
end
|
|
end
|
|
```
