I've got a little problem with the findPath function.
I'm working with a mix of two tutorials (one from Haxeflixel, and the second from haxecoder) and the second one uses CSV instead of Ogmo and uses a findPath when we click.
But when I click, the game crashes, nice.
This is my code: http://hastebin.com/xunidubiyi.avrasm
The problem is on the 86th line (split into multiple lines to fit the width):
var nodes:Array<FlxPoint> = _mWalls.findPath(
FlxPoint.get(
_player.x + 16 / 2,
_player.y + 16 / 2
),
FlxPoint.get(
tileCoordX * 16 + 16 / 2,
tileCoordY * 16 + 16 / 2
)
);
Output:
Invalid field access : allowCollisions

Does anybody know what went wrong and why?

I want to create a point in polygon query for 14million NYC taxi trips and find out which of the 263 taxi zones the trips were located.
I want to the code on RAPIDS cuspatial. I read a few forums and posts, and came across cuspatial polygon limitations that users can only perform queries on 32 polygons in each run. So I did the following to split my polygons in batches.
This is my taxi zone polygon file

There are 263 polygons/ taxi zones in total - I want to do queries in 24 batches and 11 polygons in each iteration.
def create_iterations(start, end, batches):
iterations = list(np.arange(start, end, batches))
iterations.append(end)
return iterations
pip_iterations = create_iterations(0, 264, 24)
#loop to do point in polygon query in a table
def perform_pip(cuda_df, cuspatial_data, polygon_name, iter_batch):
cuda_df['borough'] = " "
for i in range(len(iter_batch)-1):
start = pip_iterations[i]
end = pip_iterations[i+1]
pip = cuspatial.point_in_polygon(cuda_df['pickup_longitude'], cuda_df['pickup_latitude'],
cuspatial_data[0][start:end], #poly_offsets
cuspatial_data[1], #poly_ring_offsets
cuspatial_data[2]['x'], #poly_points_x
cuspatial_data[2]['y'] #poly_points_y
)
for i in pip.columns:
cuda_df['borough'].loc[pip[i]] = polygon_name[i]
return cuda_df
When I ran the function I received a type error. I wonder what might cause the issue?
pip_pickup = perform_pip(cutaxi, cusptaxizone, pip_iterations)
TypeError: perform_pip() missing 1 required positional argument: 'iter_batch'
It seems like you are passing in cutaxi for cuda_df, cusptaxizone for cuspatial_data and pip_iterations for polygon_name variable in perform_pip function. There is no variable/value passed for iter_batch defined in perform_pip function:
def perform_pip(cuda_df, cuspatial_data, polygon_name, iter_batch):
Hence, you get the above error which states that iter_batch is missing. As stated in the above comment as well you are not passing the right number of parameters for perform_pip function.
If you edit your code to pass in the right number of variables to perform_pip function the above mentioned error :
TypeError: perform_pip() missing 1 required positional argument: 'iter_batch'
would be resolved.
I am trying to reading this pajek file in Google Colab's version of Jupyter and I get an error when executing the following very simple code:
J = nx.MultiDiGraph()
J=nx.read_pajek("/content/data/graphdatasets/jazz.net")
print(nx.info(J))
The error is the following:
/usr/local/lib/python3.6/dist-packages/networkx/readwrite/pajek.py in parse_pajek(lines)
211 except AttributeError:
212 splitline = shlex.split(str(l))
--> 213 id, label = splitline[0:2]
214 labels.append(label)
215 G.add_node(label)
ValueError: not enough values to unpack (expected 2, got 1)
With pip show networkx, I see that I'm running Networkx version: 2.3. Am I doing something wrong in the code?
Update: Pasting below the file's first few lines:
*Vertices 198
*Arcs
*Edges
1 8 1
1 24 1
1 35 1
1 42 1
1 46 1
1 60 1
1 74 1
1 78 1
According to the Pajek definition the first two lines of your file are not according to the standard. After *vertices n, n lines with details about the vertices are expected. In addition, *edges and *arcs is a duplicate. NetworkX assumes use for an edge list, which started with *arcs a MultiDiGraph and for *edges a MultiGraph (see current code). To resolve your problem, you only need to delete the first two lines of your .net-file.
I have a tabular.text file (Named "xfile"). An example of its contents is attached below.
Scaffold2_1 WP_017805071.1 26.71 161 97
Scaffold2_1 WP_006995572.1 26.36 129 83
Scaffold2_1 WP_005723576.1 26.92 130 81
Scaffold3_1 WP_009894856.1 25.77 245 43
Scaffold8_1 WP_017805071.1 38.31 248 145
Scaffold8_1 WP_006995572.1 38.55 249 140
Scaffold8_1 WP_005723576.1 34.88 258 139
Scaffold9_1 WP_005645255.1 42.54 446 144
Note how each line begins with Scaffold(y)_1, with y being a number. I have written the following code to print each line beginning with the following terms, Scaffold2 and Scaffold8.
with open("xfile", 'r') as data:
for line in data.readlines():
if "Scaffold2" in line:
a = line
print(a)
elif "Scaffold8" in line:
b = line
print(b)
I was wondering, is there a way you would recommend incrementing the (y) portion of Scaffold() in the if and elif statements?
The idea would be to allow the script to search for each line containing "Scaffold(y)" and storing each line with a specific number (y) in its own variable to be then printed. This would obviously be much faster than entering in each number manually.
You can try this, it is quite easier than using Regex. If this isn't what you expect, let me know, I'll change the code.
for line in data.readlines():
if line[0:8] == "Scaffold" and line[8].isdigit():
print(line)
I'm just checking the 9th Position in your line, i.e. (8th index). If it's a digit, I'm printing the line. Like you said, I'm printing if your "y" is a digit. I'm not incrementing it. The work of incrementation is already been done by your for loop.
Ok it seems like you want to get something in format like:
entries = {y1: ['Scaffold(y1)_...', 'Scaffold(y1)_...'], y2: ['Scaffold(y2)_...', 'Scaffold(y2)_...'], ...}
Then you can do something like that (I assume all of your lines start in the same manner as you have shown, so the y value is always the 8th position in the string):
entries = dict()
for line in data.readlines():
if not line[8] in entries.keys():
entries.update({line[8]: [line]})
else:
entries[line[8]].append(line)
print(entries)
This way you will have a dictionary in the format I have shown you above - output:
{'2': ['Scaffold2_1 WP_017805071.1 26.71 161 97', 'Scaffold2_1 WP_006995572.1 26.36 129 83', 'Scaffold2_1 WP_005723576.1 26.92 130 81'], '3': ['Scaffold3_1 WP_009894856.1 25.77 245 43'], '8': ['Scaffold8_1 WP_017805071.1 38.31 248 145', 'Scaffold8_1 WP_006995572.1 38.55 249 140', 'Scaffold8_1 WP_005723576.1 34.88 258 139'], '9': ['Scaffold9_1 WP_005645255.1 42.54 446 144']}
EDIT: tbh I still don't fully understand why would you need that tho.

Code to save details from database I'm trying to save what i have entered to a file but the error INVALID CHANNEL AT LINE 490 APPEARS/
If your error is on line 490, one of two things is likely happening.
Your FILEHANDLE for phonenos did not open.
You could be attempting to access the file from a bad location, it may not exist, or it could be write protected.
Your contact array is referencing an invalid index item.
Is counter going outside the range of the array? Is this a zero (0) or one (1) based array?
I use MagicalRecord for my CoreData store. I have a statement that is generating multiple crashes by different users when this statement is executed:
PreferenceData *prefDataFound = [PreferenceData MR_findFirst];
The error is:
+entityForName: nil is not a legal NSManagedObjectContext parameter searching for entity name 'PreferenceData'
coming from this sequence of calls (from Crashlytics):
1 libobjc.A.dylib objc_exception_throw + 30
2 CoreData +[NSEntityDescription entityForName:inManagedObjectContext:] + 104
3 SalonBook NSManagedObject+MagicalRecord.m line 91
+[NSManagedObject(MagicalRecord) MR_entityDescriptionInContext:]
4 SalonBook NSManagedObject+MagicalRequests.m line 19

6 SalonBook NSManagedObject+MagicalFinders.m line 86
+[NSManagedObject(MagicalFinders) MR_findFirst]
7 SalonBook SubViewGrid.m line 37
-[SubViewGrid drawRect:]
All of this indicates to me that there is no valid context for the MR_findFirst call; oher than using *MR_findFirstWithPredicate:* (for which I have no predicate, I just want the first and only record), what can I do to fix this?
You can call
PreferenceData *prefDataFound = [PreferenceData MR_findFirstInContext:context];
with your current context, instead of relying on Magical Record to determine the
current context magically.
