Radish Beavers

if you want to work on some python while you wait, i need to figure out how to make @someonewithpc 's ray bounce more than once. latest .blend

GiantCowFilms

Okay

On another note, 300 messages untli I hit 35k total messages in this room

@RadishBeavers Why don't you just run the script every logic tick?

Radish Beavers

20:17

@GiantCowFilms it is.

but idk how the script works, but it only bounces once

if you have another object mirror, it doesnot bounce

GiantCowFilms

@RadishBeavers I see what the issue is

someonewithpc

@GiantCowFilms Does that already

GiantCowFilms

We need to recurse shoot

run it on the new vector

someonewithpc

That's what I'm doing

I just didn't design it for that at the time

GiantCowFilms

I'm adjusting it now

How do you pass a param when you run a python module?

someonewithpc

20:25

If only there were a do-while in Python

GiantCowFilms

@someonewithpc I wanna use recursion

someonewithpc

@GiantCowFilms What parameter?

GiantCowFilms

def shoot(self,vec):

is the new version of shoot I want to use

nvm, there is a work around

someonewithpc

@GiantCowFilms Just do another function

GiantCowFilms

figured that :)

@someonewithpc btw, why do you pass in self as the first param?

is that necessary?

someonewithpc

20:27

Yes it is an implicit argument

GiantCowFilms

I think a for loop will be better actually

more effcient

someonewithpc

As opposed to a binding like in all other languages

GiantCowFilms

mirror, location, normal = obj.rayCast(vec, None, 60)

hitObj, hitLocation, hitNormal = mirror.rayCast(reflectedVec, location, 60)

I feel like only one of those is needed?

your code isn't very clear

3 rep from 23

might start answering again

someonewithpc

It first casts a ray from the emitter to the (possible) mirror

And then it casts a new ray from the hitLocation, in the direction of reflectedVec

GiantCowFilms

20:31

and what does the second one do

But why twice

someonewithpc

@GiantCowFilms Because it was designed to only use one mirror

GiantCowFilms

I see

while True:
    mirror, location, normal = obj.rayCast(vec, None, 60)#, obj #, 0, "", 1, 0)
    #print(mirror, location, normal)
    if mirror != None:
        vec = vec.reflect(normal)
        print(mirror)
    else:
        print("no mirror found")
        break

That should work

but its not finding the second mirror

found my error

@RadishBeavers

import mathutils
import bge

game_objects = bge.logic.getCurrentScene().objects



def shoot(self):
    startVec = mathutils.Vector((0, 1, 0));
    obj = self.owner
    vec = mathutils.Vector((0, 1, 0)) #obj.localOrientation #
    sender = obj
    while True:
        mirror, location, normal = sender.rayCast(vec, None, 60)#, obj #, 0, "", 1, 0)
        #print(mirror, location, normal)
        if mirror != None:
            vec = vec.reflect(normal)
            print(mirror)
            sender = mirror

That should work

for any number of mirrors

someonewithpc

The bge and game objects part are not needed

Only there cause I was testing

@GiantCowFilms That doesn't work

GiantCowFilms

?

bug?

someonewithpc

It only lists the morrors

GiantCowFilms

20:37

what do you mean?

It produces the results I would expect.....?

someonewithpc

Let me check something

@GiantCowFilms Never does it equal the last object

GiantCowFilms

what do you mean?

someonewithpc

It only does two mirrors!

GiantCowFilms

sender = mirror

I think it works....?

I need more explination

someonewithpc

It's only doing two for me

GiantCowFilms

20:40

I'm not seeing it

@someonewithpc I noticed that

but I don't see why

Radish Beavers

@GiantCowFilms yes?

GiantCowFilms

nvm

there is a bug

Radish Beavers

@someonewithpc is my PR guy

talk to him

llol

someonewithpc

Lol

GiantCowFilms

@someonewithpc Where is the bug?

It looks like it should work.....

someonewithpc

20:41

@GiantCowFilms Not sure yet

GiantCowFilms

Ah okay

so its not just me

someonewithpc

Got it

GiantCowFilms

O.o?

someonewithpc

But it is infinitely recursive

GiantCowFilms

?

Where was the bug?

@someonewithpc That can happen

someonewithpc

20:44

@GiantCowFilms For some reason, the vec is not the direction relative to the object, it is absolute

GiantCowFilms

its pretty simple to check for

@someonewithpc What.

someonewithpc

Yeah, I know

GiantCowFilms

Meaning?

someonewithpc

mirror, location, normal = sender.rayCast(sender.worldPosition + vec, None, 60)

GiantCowFilms

Oops

I got into a recursion loop

I pointed a mirror back

so it goes into a loop

someonewithpc

20:46

@GiantCowFilms Your code is weirdly factored

GiantCowFilms

What do you mean?

someonewithpc

Which is why I wanted a do-while

@GiantCowFilms Told you

GiantCowFilms

Pretty easy to check for

someonewithpc

@GiantCowFilms the if-else construct inside the loop

GiantCowFilms

If the vector goes out the same way it comes in, we are going to end up in a loop

@someonewithpc It breaks, when the laser goes off into space

???

It breaks out of the loop when it doesn't find a mirror

you only get stuck in a loop if you shoot the ray back where it came...

someonewithpc

20:48

do:
    #shoot ray
while mirror != None

GiantCowFilms

Difference?

My code works

    else:
        print("no mirror found");
        break

no infinite loop

someonewithpc

    import mathutils

    def shoot(self):
        startVec = mathutils.Vector((0, 1, 0));
        obj = self.owner
        vec = mathutils.Vector((0, 1, 0)) #obj.localOrientation #
        sender = obj
        while True:
            mirror, location, normal = sender.rayCast(sender.worldPosition + vec, None, 60)#, obj #, 0, "", 1, 0)
            #print(mirror, location, normal)
            if mirror != None and mirror.name.find("Mirror") != -1:
                vec = vec.reflect(normal)
                print(mirror)

@RadishBeavers ^^

@GiantCowFilms There is

GiantCowFilms

I don't see it!

its not happening.

someonewithpc

GiantCowFilms

@someonewithpc Thats the same

Radish Beavers

20:52

@someonewithpc is that the finished code/?

someonewithpc

@GiantCowFilms You said that as I just clicked that link on the sidebar :P

@RadishBeavers Should

Radish Beavers

okay.

someonewithpc

Unless you or @GiantCowFilms find any bug

GiantCowFilms

@someonewithpc Why is my code looping though

@someonewithpc There is one

Radish Beavers

so i just replace your old code with that?

someonewithpc

20:53

@GiantCowFilms No, it's not

GiantCowFilms

WHATS THE DIFFERECNE

you don't explain

Radish Beavers

@GiantCowFilms where?

GiantCowFilms

you just keep saying "its wrong"

someonewithpc

I check for the object name, so that it only reflects on mirros

GiantCowFilms

but then you don't explain why

someonewithpc

20:53

@GiantCowFilms I am...

GiantCowFilms

@someonewithpc How does that avoid an infinite loop.....

someonewithpc

@GiantCowFilms Because only objects named mirror should act as mirrors

1 min ago, by Radish Beavers

@GiantCowFilms where?

GiantCowFilms

@someonewithpc Oh

You made it sound different

But there is a better way, @someonewithpc

someonewithpc

@GiantCowFilms How?

@GiantCowFilms Which?

GiantCowFilms

@someonewithpc Check if the vector reflecting goes back the same direction, its less work

someonewithpc

20:57

@RadishBeavers Why? They're not frequently used, but it would fit for this ocasion

@GiantCowFilms No, that's worse

GiantCowFilms

No

someonewithpc

Then it's not universal

GiantCowFilms

Your method cuases the ray to bounce all the way back to the start

someonewithpc

@GiantCowFilms That would only work in the case where it lines up exactly

GiantCowFilms

And I think I can find a way to get it into an infite loop anyway

someonewithpc

20:58

And it would still reflect on non mirrors

@GiantCowFilms You use only mirrors, yeah

gandalf3

@GiantCowFilms idk.. never bothered

GiantCowFilms

@someonewithpc Your code doesn't work

someonewithpc

@GiantCowFilms No it doesn't, unless you only use mirrors

@GiantCowFilms Why?

GiantCowFilms

@gandalf3 I managed in the end, I can even let you use it :)

@someonewithpc You can only have one object named mirror

@RadishBeavers sorry for not sending you the stuff yet. My siblings stole the computers. But I got the pillars done and a couple tile designs.
