Question

I need an function(collapsion test) to test if 2 shapes collapsed or not ^^

Answer 1

i tried to do it like that:

if Xshape1 == Xshape 2 and if Yshape1==Yshape2 then Collapse = ture else false

Answer 2

failed :(

Answer 3

And it should push back ^^

Answer 4

ty :D

Answer 5

if ((imgX1 == imgX2) && (imgY1 == imgY2))
{alert('collapsed')}
else {alert('failed')}

Answer 6

alert is just a display function

Answer 7

I usually break it into flags instead of going for the whole boolean

Answer 8

amm kk as i do ^^
so alres gives true to collapsed value ye?

Answer 9

but amistre i tried it too and it didn'T work :(

Answer 10

id have to see the programming to really get an understanding of it...

Answer 11

hmm kk but i have an idea just wait

Answer 12

OK I GOT IT JUST LOOK and a "ve" means and in turkish :( i wrote it turkish because of my agitation sorry :(

Answer 13

just look at these amistre

Answer 14

height and width /2 is center of image good; x and y are plots...

Answer 15

yea..

Answer 16

to you, will it work nice?

Answer 17

still looking it over; when do you want to call the collision? at center points of when edges meet?

Answer 18

i want to call when edges meet

Answer 19

no centers

Answer 20

are they both inmotion? or is one stationary?

Answer 21

yea they are in motion

Answer 22

so that, when they collapse, i want them to push back too

Answer 23

well, push back would be just a negation right? opoosite direction of motion

Answer 24

yea

Answer 25

collision happens regardless of both in motion so its simply breaching the area of the other then...

Answer 26

and it hink that
if we have a variable named speed
speed should be-0.1 f 60 times per sec yea?

Answer 27

u right , so when it collapese if it moves on X+1 direction it will move in X-1 direction and speed -0.1f 60 times per sec and if speed < 0 the it should stop ya?

Answer 28

cant say fer sure on speed yet but.... for collision I get:

if Cxmin = xb-(hb/2) ; Cxmax = xb+(hb/2)

Answer 29

no 'if' there lol just naming variables

Answer 30

yea its like that

Answer 31

ok kk ^^
i am so unpatinet xp

Answer 32

maybe better to name then Axmin, Aymin, Axmax, Aymax, and such right?

Answer 33

amistre u know i am only 14 years old and I am not in highschool yet xd
yea

Answer 34

if (Bxmin <= Axmax AND Bxmin >= Axmin) {then collapse}

Answer 35

im 39 so.... so lets keep it proper :)

Answer 36

:)

Answer 37

well its logical

Answer 38

that would generate a collapse if they are inline along the xaxis

Answer 39

factor in the y axis the same way and it should cover all diretions then

Answer 40

whatever your alogrithm for motion is, reverse it

Answer 41

and t
then do same thing for y axis
and put them
if if (Bxmin <= Axmax AND Bxmin >= Axmin) {then collapsex=ture}
and for the other equatin is ture then collapsey=ture
and if collapsex==ture and collapsey== ture then collapse==True!!!!!!!!

Answer 42

OMG!!! u solved tht? O.o

Answer 43

you got it :) maybe an easier way to do it, but I never go that route lol

Answer 44

xd
anyway we solved this it hink and tomorrow ill try to program it

Answer 45

good luck :)

Answer 46

name your corners; and when they are between each other or equal to each other, collapse

Answer 47

i wanted this collapsion thest to see if cannonball collapsed with theenemey ship

Answer 48

kk thank you

Answer 49

well i wrote algorithm for pushing back :D its ok now

Answer 50

really good work here
