I want to get polygon edge positions 3Ds Max with maxscript. I have tried the following:
tmesh = snapshotAsMesh selection[1]
out_name = ((GetDir #export)+"/testmesh.dat")
out_file = createfile out_name
num_verts = tmesh.numverts
num_faces = tmesh.numfaces
format "% % %\n" num_verts num_faces to:out_file
for v = 1 to num_verts do
(
vert = getVert tmesh v
format "%," vert to:out_file
)
format "\n" to:out_file
for f = 1 to num_faces do
(
face = getFace tmesh f
format "%," face to:out_file
)
close out_file
delete tmesh
edit out_name
Output needs to be something like OBJ file format, but I want to have only edge connections showed in wire frame.
Sample output:
[0,0,0],[1,0,0],[0,1,0],[1,1,0]
[1,2],[2,3],[3,4],[4,1]
EDIT:
I could find invisible edges via this code.
for f = 1 to num_faces do
(
face = getFace tmesh f
edge1 = getEdgeVis tmesh f 1
edge2 = getEdgeVis tmesh f 2
edge3 = getEdgeVis tmesh f 3
format "%,[%,%,%]" face edge1 edge2 edge3 to:out_file
format "\n" to:out_file
)
You can get the vertices for an edge using meshop.GetVertsUsingEdge like this:
tmesh = snapshotAsMesh selection[1]
allverts = #()
for v = 1 to num_verts do
(
vert = getVert tmesh v
append allverts vert
)
print allverts
format "\n" --to:out_file
edges = tmesh.Edges
for ed in edges do
(
print ed
edverts = meshop.GetVertsUsingEdge tmesh ed
print "ed verts: "
for v in edverts do (
print allverts[v]
)
print "\n"
)
delete tmesh

My code is designed to count the the letters that appears in 2 separate names, including the overlapping characters. it should take two names (name = 1st name + last name) and count the number of times the letters "T R U E L O V E" show up.
My code is:
''' # 🚨 Don't change the code below 👇
print("Welcome to the Love Calculator!")
name1 = (input("What is your name? \n"))
name2 = input("What is their name? \n")
# 🚨 Don't change the code above 👆
#Write your code below this line 👇
names = name1 + name2
lowernames = names.lower()
t = lowernames.count("t")
r = lowernames.count("r")
u = lowernames.count("u")
e = lowernames.count("e")
l = lowernames.count("l")
o = lowernames.count("o")
v = lowernames.count("v")
e = lowernames.count("e")
true = t + r + u + e
love = l + o + v + e
love_score = int(str(true) + str(love))
print(love_score)
if (love_score < 10) or (love_score > 90):
print(f"your love score is {score} you fit together like montos and coke")
elif (love_score >= 45) and (love_score <= 50):
print(f"your love score is {love_score} you are alright together")
else:
print(f"your love score is {love_score}")

The names I've entered in are:
Yonatan Allon (should give 2 O's and 2 L's)
Guy Hazan (one U)
I don't get why the score that comes up is 24 and not 41
Can someone please help me fix this?
Thanks in advance, Yonatan :)
While using the real-time Fractal zoomer XaoS to explore the infinite universe having user formula "sin(z^2)-cos(z^2)+c", we start out here (important for universe identification and formula matching with other zoomer software applications, libraries or frameworks.):
I found the following fractal, which I really like:
As you, perhaps, can see, I have run up against the resolution wall (floor?), which means that the deeper I zoom at that point, the more pixelated and boxy the image gets:
Here is the XaoS source code (*.xpf file contents):
;Position file automatically generated by XaoS 4.2.1
; - a realtime interactive fractal zoomer
;Use xaos -loadpos <filename> to display it

And Fractal->View... yields:
So I tried to enter the formula into UltraFractal, but no matter what I try, I can't get it to work.
This works:
init:
z = #start
loop:
z = sin(z^#power) + cos(z^#power) + #pixel
This does not work:
init:
z = #start
loop:
z = sin(z^#power) - cos(z^#power) + #pixel
The only difference in the above two is the minus sign.
This does not work:
init:
z = #start
loop:
z2p = z^#power
ss = sin(z2p)
cc = cos(z2p)
z = ss - cc + #pixel
This works:
init:
z = #start
loop:
z2p = z^#power
ss = sin(z2p)
cc = cos(z2p)
z = ss + cc + #pixel
but if I add a line negating cc, it doesn't work again:
init:
z = #start
loop:
z2p = z^#power
ss = sin(z2p)
cc = cos(z2p)
cc = -cc
z = ss + cc + #pixel
Finally, one last example.
This works:
init:
z = #start
loop:
z2p = z^#power
ss = sin(z2p)
cc = cos(z2p)
z = ss + 1 - ( 1 - cc ) + #pixel
but this doesn't:
init:
z = #start
loop:
z2p = z^#power
ss = sin(z2p)
cc = cos(z2p)
z = ss + 1 - ( 1 + cc ) + #pixel
As I think I've proven, negation and subtraction seem to be working. And I keep changing only the minus sign or the subtraction to make it stop working, so I suspect that there is a bug (or an arbitrary limitation of not being able to use this particular formula? - doesn't make sense.)
In the "Fractal Mode" pane, lower right part of screen, I click the third item down, "Switch Mode", and it displays "Contains errors." This is the only helpful feedback I've been able to find.
This is a paid program, so I do not expect to be having this problem. Anyone? (secondary question - what zoomer will render this well? Thanks!)
Here is my current UltraFractal source code:

I just punched the formula into a zoomer on my Android, and it seems to work.
Here is that coordinate, zoomed out just a little, so that you can barely see the pixelated fractal (just another example of great beauty from this wonderful infinite universe!):
EDIT:
This formula works:
init:
z = #start
loop:
; in XaoS, user formula sin(z)^2-cos(z)^2+c
z = sin(z)^2 - cos(z)^2 + #pixel
And here's the result in UltraFractal:

I am working on a game where the player has to collect coins by landing on chests. However, if they land on the same chest three times, it will delete the chest that is there and will insert a bandit in its place - which will reset their coins back to zero (this part is not included in the code provided as it runs correctly).

I know you can use canvas.delete(item_id) to remove an object, given that it has been defined but my problem is that since I created my objects with a dictionary, they do not have specific names which I could use and I would like to know how I can delete an object from a canvas based on what it's coordinates are rather than it's name.
Also, as a side note, since I am using images, according to answers I have found on , the format has to be GIF, but I am able to use the PNG format and it still works fine but when I try my game on a different device, I get the expected error. Is there a reason for this?
With the help of furas, I have found a solution:
Since each chest has its own unique row and column, you can refer to an individual chest using its row and column, meaning we must find out what that row and column could be.
Because x1 = col * CELL_WIDTH + 24 and y1 = row * CELL_HEIGHT - 26 where x1 is the x coordinate and y1 is the y coordinate, the equations for the row and column must be (x1 - 24) / CELL_WIDTH = col and (y1 + 26) / CELL_HEIGHT = row.
You would then substitute for the x and y coordinates using arrow_coords[0] and arrow_coords[1]. And to get the specific row and column from the chest_dict, you would then round it to the nearest whole number and it will delete that specific chest from the canvas:
game_grid.delete(chest_dict[int(round(int(arrow_coords[0]-24)/50, 0)),
int(round(int(arrow_coords[1]+26)/50, 0))])
In Python, using IDLE 3.4 (x64), I have created a two-dimensional list of 3 rows and 2 columns. I then had the list populate with random numbers.
Now I want to display the sum values in the rows and then display the sum of the columns, and I'm at a loss for how to do that.
Here is what I have so far:
import random
def main():
#Create nested loop
rows = 3
cols = 2
values = [[0,0],
[0,0],
[0,0]]
#Generate random integers in list
for r in range(rows):
for c in range(cols):
values[r][c] = random.randint(1, 100)
#Display results
print(values)
main()
Here is what I got:
import random
def main():
#Create nested loop
rows = 3
cols = 2
values = [[0,0],
[0,0],
[0,0]]
#Generate random integers in list
for r in range(rows):
for c in range(cols):
values[r][c] = random.randint(1, 100)
#Display results
print(values)
sum_2 = 0
sum_3 = 0
sum_2_list = []
sum_3_list = []
length = len(values)
for num in range(0, length):
sum = values[num][0] + values[num][1]
print('{} + {} = {}'.format(values[num][0], values[num][1], sum))
for num2 in range(0, length):
sum_2 = sum_2 + values[num2][0]
sum_3 = sum_3 + values[num2][1]
print('{} + {} + {} = {}'.format(values[0][0], values[1][0], values[2][0], sum_2))
print('{} + {} + {} = {}'.format(values[0][1], values[1][1], values[2][1], sum_3))
