I have a few codes below.
local mBackground = loader:loadBackground()
localGroup:insert(mBackground)
local mAnimals = loader:loadAnimal()
localGroup:insert(mAnimals)
local mDoor = loader:loadDoor()
localGroup:insert(mDoor)
The animals should always be left behind the door, but it can be updated by running the load function of loader few times.
I want to keep them behind the door whenever they are updated. How can I do that?
I used toBack(), but it doesn't seem right.
toBack() will make the object to the back of the group
toFront() will make the object to the front of the group
There is no way to move the object 1 index backward or forward, like move forward or move backward.
The method on your case will be this
mAnimals:toFront()
mDoor:toFront()
It's a little bit brute force, but it will solve the problem.
you can put an object on different index group buy doing this
local mBackground = loader:loadBackground()
localGroup:insert(1,mBackground) -- move object from index 1
local mAnimals = loader:loadAnimal()
localGroup:insert(2,mAnimals) -- move object from index 2
local mDoor = loader:loadDoor()
localGroup:insert(3,mDoor) -- move object from index 3
you can even change/update it's index if you want or put the same object in the same index

I want to use or tools to solve the CVRP problem and I know can use routing.IsVehicleUsed(assignment, vehicle_id) method know the vehicle is used or not.
Can I reuse the used vehicle.
Because I have a problem ,when I set data['num_vehicles'] = 1 or-tools returns no result but when I set data['num_vehicles'] = 4 I got a solution.
It cannot be modified the data['vehicle_capacities'] so I want to the used vehicle can start again when it return start point
Once a vehicle reach its end node, it's over. End node are always the last node of a vehicle route.
You should create some dummy node (duplicate of depot) to simulate an unload please take a look at the refuel station example in the sample directory on github...
When you try to reach the Dalaran Well in Dalaran, you are teleported to the sewers.
It is using this Game object: Doodad_Dalaran_Well_01 (id = 193904 )
Where is it scripted? How?
I've found nothing in the table smart_scripts, and found nothing in the core about this specific id so I'm curious because this type of teleport is really better than clicking on a game object
This gameobject is a unique case because it works like instance teleports do. If you check the gameobject_template table, you will see that it has several Data columns that have diferent values based on the type of the gameobject.
The gameobject you are refering too is the Well It self but the portal gameobject inside the well gives the player a dummy spell to tell the core that the player has been teleported (spell ID 61652).
For the specific case of the dalaran well, it's type is 30 which means, as the documentation says, GAMEOBJECT_TYPE_AURAGENERATOR. As soon as the player is in range, a dummy aura is cast on him to notify the core that this areatrigger has been activated (You could do stuff when player gets hit by the dummy spell).
The trick here is a bunny, but not the bunny itself since it is there mostly to determine an areatrigger. If you use command .go gobject 61148 you can check him out, he's inside the well.
Areatriggers are a DBC object that are actually present on our database on world.areatrigger. You can check the columns here. When the player enters the Radius box specified on the areatrigger, another thing happens in the core which is world.areatrigger_teleport.
If you run the following query you will be able to check the position where the trigger will teleport the player to.
SELECT * FROM areatrigger_teleport WHERE `Name` LIKE '%Dalaran Well teleporter%';
For several years I have been using the CGridCellCombo class. It is designed to be used with the CGridCtrl.
Several years ago I did make a request in the comments section for an enhancement but I got no replies.
The basic concept of the CGridCellCombo is that it works with the text value of the cell. Thus, when you present the drop list it will have that value selected. Under normal circumstances this is fine.
But I have places where I am using the combo as a droplist. In some situations it is perfectly fine to continue to use the text value as the go-between.
But is some situations it would have been ideal to know the actual selected index of the combo. When I have a droplist and it is translated into 30 languages, and I need to know the index, I have no choice but to load the possible options for that translation and then examine the cell value and based on the value found in the array I know the index.
It works, but is not very elegant. I did spend a bit of time trying to keep track of the selected index by adding a variable to CInPlaceList and setting it but. I then added a wrapper method to the CGridCellCombo to return that value. But it didn't work.
I wondered if anyone here has a good understanding of the CGridCellCombo class and might be able to advise me in exposing the CComboCell::GetCurSel value.
I know that the CGridCtrl is very old but I am not away of another flexible grid control that is designed for MFC.
The value that is transfered back to the CGridCtrl is choosen in CInPlaceList::EndEdit. The internal message GVN_ENDLABELEDIT is used, and this message always use a text to set it into the grid.
The value is taken here via GetWindowText from the control. Feel free to overwrite this behaviour.
The handler CGridCtrl::OnEndInPlaceEdit again calls OnEndEditCell. All take a string send from GVN_ENDLABELEDIT.
When you want to make a difference between the internal value and the selected value you have to manage this via rewriting the Drawing and selecting. The value in the grid is the GetCurSel value and you have to show something different... There isn't much handling about this in the current code to change.
More information
The key is CInPlaceList::EndEdit(). There is a call to GetWindowText (CInPlaceList is derived from CComboBox), just get the index here. Also in CGridCellCombo::EndEdit you have access to the m_pEditWnd, that is the CInPlaceList object and derived from CComboBox, so you have access here too.
I have found this to be the simplest solution:
int CGridCellCombo::GetSelectedIndex()
{
int iSelectedIndex = CB_ERR;
CString strText = GetText();
for (int iOption = 0; iOption < m_Strings.GetSize(); iOption++)
{
if (strText.CollateNoCase(m_Strings[iOption]) == 0) // Match
{
iSelectedIndex = iOption;
break;
}
}
return iSelectedIndex;
}
I'm trying to mask the answer options that show up in a 3DGrid question item in Confirmit, using the value of a background variable.
E.g. when "background1" ==1, display answer category 1. If "background1" ==0, do not display answer category 1. If "background2" ==1, display category 3, otherwise do not. In any case, display answer category 2.
Hopefully this is easy for someone out there (I'm a psychologist, not a coder...so not so much so for me :/)
Thanks!
In order to access the data inside a question/variable we can use the f function of confirmit.
for instance:
f('my_question_id').get();
When masking a question, we need to pass in a Set object so Confirmit knows what Code's to show and not to show.
Often you will mask using a Set from a previous question. So you pass in the question_id and Confirmit does all the other magic.
Here we have the problem of not having a Set, so we will have to create our own.
For this, there are 2 approaches (can be found in the scripting manual under Working with Sets > Methods of the set Object > add and remove and Working with Sets > User defined functions...)
I'm going to stick to the first one because it is easier to use ;)
What we will do first is create a script node (it doesn't matter where you create it, just somewhere in the survey, I often have a folder Functions with all my script nodes in somewhere at the bottom of my survey)
In that script file we will have our function that crates our set:
function CreateMyAwesomeSet()
{
//create an empty Set
var mySet = new Set();
//if background1 equals 1, add 1 to our Set
if ( f('background1').get() == '1' )
{
mySet.add(1);
}
//return the Set of allowed Codes
return mySet;
}
Here we declare a function that we now can use wherever we want to.
So now, If we want to use this Set, we add a Code Mask to your grid:
CreateMyAwesomeSet()
You can ofcourse change the name of the function, and add extra if statements.
hope this helps
I am making a game in Game Maker right now and cannot figure out how to get an objects exact position and have another object move to that position. Can someone please help me?
To get an object's position simply use
xpos = instance.x;
ypos = instance.y;
where instance is the instance id (gained through some method, object id can be used if the instance is the only instantiation of the object).
To start moving towards a position you should set the speed & direction:
direction = point_direction(x,y, instance.x, instance.y);
speed = WANTEDSPEED;
The object position are two variables (x,y)
You can access them as you would do with any other variable (objectName.variable)
So these two would be, as paul23 said:
object.x
object.y
To make the object move towards a point you can better use this built-in function:
move_towards_point(object.x,object.y,speed)
It'll move by speed pixels every time it's executed so you may want to put it in the Step event.
