How to look through the array in React?
yo
u can use like this .u can keep it in a variable name and u can check in which key ur getting the array of datas , then you can map the fields and u will get data
enter image description here
So I'm making a little text based game in Python and I decided for a save system I wanted to use the old "insert code" trick. The code needs to keep track of the players inventory (as well as other things, but the inventory is what I'm having trouble with).
So my thought process on this would be to tie each item and event in the game to a code. For example, the sword in your inventory would be stored as "123" or something unique like that.
So, for the code that would generate to save the game, imagine you have a sword and a shield in your inventory, and you were in the armory.
location(armory) = abc
sword = 123
shield = 456
When the player inputs the command to generate the code, I would expect an output something like:
abc.123.456
I think putting periods between items in the code would make it easier to distinguish one item from another when it comes to decoding the code.
Then, when the player starts the game back up and they input their code, I want that abc.123.456 to be translated back into your location being the armory and having a sword and shield in your inventory.
So there are a couple questions here:
How do I associate each inventory item with its respective code?
How do I generate the full code?
How do I decode it when the player loads back in?
I'm pretty damn new to Python and I'm really not sure how to even start going about this... Any help would be greatly appreciated, thanks!
So, if I get you correctly, you want to serialize info into a string which can't be "saved" but could be input in your program;
Using dots is not necessary, you can program your app to read your code without them.. this will save you a few caracters in lenght.
The more information your game needs to "save", the longer your code will be; I would suggest to use as short as possible strings.
Depending on the amount of locations, items, etc. you want to store in your save code: you may prefer longer or shorter options:
digits (0-9): will allow you to keep 10 names stored in 1 character each.
hexadecimal (0-9 + a-f, or 0-9 + a-F): will allow you to keep from 16 to 22 names (22 if you make your code case sensitive)
alphanum (0-9 + a-z, or 0-9 + a-Z): will allow you to keep from 36 to 62 names (62 if case sensitive)
more options are possible if you decide to use punctuation and punctuated characters, this example will not go there, you will need to cover that part yourself if you need.
For this example I'm gonna stick with digits as I'm not listing more than 10 items or locations.
You define each inventory item and each place as dictionaries, in your source code:
You can a use single line like I have done for places
places = {'armory':'0', 'home':'1', 'dungeon':'2'}
# below is the same dictionary but sorted by values for reversing.
rev_places = dict(map(reversed, places.items()))
Or for improved readability; use multiple lines:
items = {
'dagger':'0',
'sword':'1',
'shield':'2',
'helmet':'3',
'magic wand':'4'
}
#Below is the same but sorted by value for reversing.
rev_items = dict(map(reversed, items.items()))
Store numbers as strings, for easier understanding, also if you use hex or alphanum options it will be required.
Then also use dictionaries to manage in game information, below is just a sample of how you should represent your game infos that the code will produce or parse, this portion should not be in your source code, I have intentionally messed items order to test it.;
game_infos = {
'location':'armory',
'items':{
'slot1':'sword',
'slot2':'shield',
'slot3':'dagger',
'slot4':'helmet'
}
}
Then you could generate your save code with following function that reads your inventory and whereabouts like so:
def generate_code(game_infos):
''' This serializes the game information dictionary into a save
code. '''
location = places[game_infos['location']]
inventory = ''
#for every item in the inventory, add a new character to your save code.
for item in game_infos['items']:
inventory += items[game_infos['items'][item]]
return location + inventory # The string!
And the reading function, which uses the reverse dictionaries to decipher your save code.
def read_code(user_input):
''' This takes the user input and transforms it back to game data. '''
result = dict() # Let's start with an empty dictionary
# now let's make the user input more friendly to our eyes:
location = user_input[0]
items = user_input[1:]
result['location'] = rev_places[location] # just reading out from the table created earlier, we assign a new value to the dictionary location key.
result['items'] = dict() # now make another empty dictionary for the inventory.
# for each letter in the string of items, decode and assign to an inventory slot.
for pos in range(len(items)):
slot = 'slot' + str(pos)
item = rev_items[items[pos]]
result['items'][slot] = item
return result # Returns the decoded string as a new game infos file :-)
I recommend you play around with this working sample program, create a game_infos dictionary of your own with more items in inventory, add some places, etc.
You could even add some more lines/loops to your functions to manage hp or other fields your game will require.
Hope this helps and that you had not given up on this project!
I have a model in angularJS which is bound to firebase $scope.items=$firebase(blah) and I use ng-repeat to iterate through the items.
Every item in firebase has a corresponding geofire location by the key of the item.
How can I update my controller to only include items by a custom radius around the user? I don't want to filter by distance in angular, just ask firebase to only retrieve closer items (say 0.3km around a location). I looked around geoqueries but they have a different purpose and I don't know how to bind them to the model anyway. The user may change the radius and the items list should be updated accordingly, so they need to be bound somehow.
Any suggestion is welcome, but an example would be greatly appreciated as I don't have fluency in this trio of angular/firebase/geofire yet :P
It's difficult to figure out what you need to do without seeing your code. But in general you'll need to query a Firebase ref that contains the Geohash as either the name of the child or the priority.
A good example of such a data structure can be found here: https://publicdata-transit.firebaseio.com/_geofire/i
i
9mgzcy8ewt:lametro:8637: true
9mgzgvu3hf:lametro:11027: true
9mgzuq55cc:lametro:11003: true
9mue7smpb9:nctd:51117: true
...
l
...
lametro:11027
0: 33.737797
1: -118.294708
actransit:1006
actransit:1011
actransit:1012
...
The actual transit verhicles are under the l node. Each of them has an array contains the location of that vehicle as a longitutude and latitude pair.
The i node is an index that maps each vehicle to a Geohash. You can see that the name of each node is built up as <geohash>:<metroarea>:<vehicleid>.
Since the Geohash is at the start of the name, we can filter on Geohash with a Query:
var ref = new Firebase("https://publicdata-transit.firebaseio.com/_geofire");
var query = ref.child('i').startAt(null, '9mgzgvu3ha').endAt(null, '9mgzgvu3hz');
query.once('child_added', function(snapshot) { console.log(snapshot.name()); });
With this query Firebase will give us all nodes whose name falls within the range. If all is well, this will output the name of one node:
9mgzgvu3hf:lametro:11027
Once you have that node, you can parse the name to extract the vehicleid and then lookup the actual location of the vehicle under l.
Calculating Geohashes based on a location and a range
In the snippet above, I hardcoded the geohash values to use. Normally you'll want to to get all nodes in a certain range around a center. Instead of calculating these yourself, I recommend using the geohashQueries function from GeoFire for that:
var whitehouse = [38.8977, -77.0366];
var rangeInKm = 0.3;
var hashes = geohashQueries(center, radiusInKm*1000);
console.log(JSON.stringify(hashes));
This outputs a number of Geohash ranges:
[["dqcjqch","dqcjqc~"],["dqcjr10","dqcjr1h"],["dqcjqbh","dqcjqb~"],["dqcjr00","dqcjr0h"]]
You can pass each of these Geohash ranges into a Firebase query:
hashes.forEach(function(hash) {
var query = geoFireRef.child('i').startAt(null, hash[0]).endAt(null, hash[1]);
query.once('child_added', function(snapshot) { log(snapshot.name()); });
});
I hope this helps you settings things up.
Here is a Fiddle that I created a while ago to experiment with this stuff: http://jsfiddle.net/aF9mN/.
I have a Matlab application that generates a output matrix based on user input. I want to save it to a file or files. There are two ways I have in mind:
Multiple files; one matrix per file
user1.mat
user2.mat
....
Single file allUser.mat with multiple matrix
user1=[data1]
user1=[data2]
....
However I don't know how to keep track of the number, because every user will start a new instance of the application. Any idea how to do this?
One way is to simply edit (or create, if it's not there already) the startup.m file to ask the user for their user id, and then use that to load the correct file:
user_id = input("Enter your user id: ");
load(sprintf('user%i.mat', user_id));
Another way would be to use the unix whoami function, if each user uses their own logon:
[s,w]=unix('whoami'); %# w = eykanal
load(sprintf('%s_data.mat', w));
I want a rather simple (and cheap) solution, just for presentation purposes (and just to show the task duration bars - no connection lines between them). So, I am not interested in buying some advanced custom control like this for example. Have any of you ever used something like this? Are there any code samples available?
I would have pointed to Buck Woolley's dwExtreme site for an example of how to do a gantt in native DataWindow. However, "simple" I don't think is in your future if you want to roll your own. In fact, I'll be pleasantly surprised if someone writes a posting that includes a full description; I think it would take pages. (I'd be happy if someone proved me wrong.) In the meantime, here are some DataWindow basics I think you would need:
You can create an external DataWindow whose data source is not tied to a table
Columns in the data set do not have to be shown on the user interface
Columns in the data set can be used in expressions to evaluate attributes, so you could have a column for each of the following attributes of a rectangle:
x
width
color
I'd expect this to be a lot of work and time, and very likely to be worth the purchase the component (unless your time is valued at next to nothing, which in some IT shops is close to true).
Good luck,

You can make a simple Gantt chart with a Stacked Bar Graph (BarStacked (5) in the painter). The trick is to create a dummy series to space the bar out where you want it and make the dummy bar the same color as the graph's background (BackColor). It turns out you also need another dummy series with a small value to sit on the axis. Otherwise when you change the color of the bar that's doing the spacing, the axis line gets cut off. I found that .04 works well for this value.
Create the DataWindow
(This assumes familarity with the DataWindow Wizard. Refer to the PowerBuilder User's Guide for more information on creating graphs in DataWindows)
Click the icon for the new object wizard. Create a Graph DataWindow with an External data source. Create columns task type string(20), ser type string(1), and days type number. Set the Category to the task column and the Values to the days column. Click the Series button and select ser for the series. Don't bother with the title, and select the Stacked Bar graph type. When the painter opens, save the DataWindow. On the General tab in the Painter, change the Legend to None (0). On the Axis tab, select the Category axis, then set the sort to Unsorted (0). Select the Value axis then set the sort to Unsorted (0). Select the Series axis and set the sort to Ascending (1). Save the DataWindow.
Create the Window
Create a window and place a DataWindow control, dw_1. Set the data object to your graph DataWindow. Place the following in the open event (or pfc_postopen if using PFC).
try
dw_1.setRedraw(FALSE)
// LOAD DATA HERE
dw_1.object.gr_1.title = 'Project PBL Pusher'
dw_1.object.gr_1.category.label = 'Phase'
dw_1.object.gr_1.values.label = 'Project-Days'
catch (runtimeerror re)
if isvalid(gnv_app.inv_debug) then gnv_app.inv_debug.of_message(re.text) // could do better
finally
dw_1.setRedraw(TRUE)
end try
You would load the data for your chart where the comment says // LOAD DATA HERE
Script the graphcreate Event
Add an new event to dw_1. Select pbm_dwngraphcreate for the Event ID. I like to name these events by removing the pbm_dwn prefix so I use graphcreate. Add the following code to the event.
string ls_series
long li_color
try
li_color=long(dw_1.object.gr_1.backcolor)
// note first series is a dummy with a small value (0.04 seems to work) to keep the line from being hidden
ls_series = dw_1.seriesName("gr_1", 2)
if 0 = len(ls_series) then return // maybe show error message
// will return -1 when you set color same as the graph's backcolor but it sets the color
dw_1.setSeriesStyle("gr_1", ls_series, BackGround!, li_color) // the box
dw_1.setSeriesStyle("gr_1", ls_series, ForeGround!, li_color) // the inside
catch (runtimeerror re)
if isvalid(gnv_app.inv_debug) then gnv_app.inv_debug.of_message(re.text) // could do better
end try
Data for the Graph
Load the data with the categories in the reverse order of what you want. For each Task, insert 3 rows and set the series to a, b, and c, respectively. For series a in each task, set a small value. I used 0.04. You may have to experiment. For series b in each task, set the number of days before start. For series c, set the number of days. Below is the data in the sample DataWindow.
Task Ser Days
---- --- ----
Test a 0.04
Test b 24
Test c 10
Develop a 0.04
Develop b 10
Develop c 14
Design a 0.04
Design b 0
Design c 10
