get variable from another entity

[ant0N]

The ability to access variables in an object from another object..?

I don't know how much this is feasible, but it would be really cool!
For example, this is implemented as dynamicproperty:

Code: Select all

--obj1
--[[Public|int]] health = "100"

Code: Select all

--obj2
function onTrigger_Enter(hitObj)
    hitObj_health = entity.getPublicProperty(hitObj, "health")
    hitObj_health  = hitObj_health  - 1
end

any suggestions?

Using entity.getDynamicProperty(objid, "property") could be used I think but you would have to set the dynamic property in the objects script to keep it up to date. But this then defeats the purpose of the front panel as the data would change constantly and wouldn't be what u need for easy editing of shared script.

Now your public idea is pretty cool actually. But the variable would still need set every frame if called from another location or script. Probably easier to use the setVar and getVar still or simply "callfn" passing the data.

I'm not sure? If there was a way of having the data up to date without having to set anything, then it would work great. But the scripts are parsed for dynamic properties when added or saved, they are not runtime at all except for grabbing or setting.

Hope this helps

I just wanted to get dccID in the trigger.

Code: Select all

function onTrigger_Enter(hitID)
    target_obj = hitID
    target_dcc = ?
end

I know that it is possible to use entity.callFn(), but then my script will lose versatility.

i can't seem to find a function in order to get the dccID from an entityID. I will add one in today for the next release

thanks, SP!

ok, we now have the command:

Code: Select all

dccID = controller.getBodyID(eID) -- pass in the entity to get the dccID or -1 if not a spawned dcc

This is in for the next release.

edit: this is what it would look like in action:

Code: Select all

function onTrigger_Enter(hitID)
   dccID = controller.getBodyID(hitID);
   if(dccID ~= -1)   then
      x,y,z = controller.getPosition(dccID)
      controller.setPosition(dccID, x,y+5,z);
   end   
end

When you get the lua action spawning update you can add a Damage action to manage all the objects health and then be able to get the object's health from the trigger. This is how I manage character health with the AI and Player.
