Have you tried JavaLifeSearch, or the older Windows version WLS? They can perform those tasks fairly well, depending on exactly what you want.

Can rlifesrc have a feature that skips solutions containing non-interacting objects?

Is there a script that can turn a pattern into a static png?

This Lua script will save the current pattern into Golly's temp folder as "pattern.png". Maximum pattern size is 4096 x 4096.

LifeWiki Help:Images says that you can just use the standard giffer.py with Number of generations = 1, then open the resulting .gif in any image-editing program and save as .png.
BTW in Special:UnusedFiles you can see lots of blur gray-background images (both static and animated) by exactly you. Would you mind deleting them so as to save storage space?

Here you go! Note that this only works on diagonal ships. (I'm making one for orthogonal ships.) Before using, make a layer with the ship you want to collide traveling southwest.

Code: Select all

import golly as g

shippattern = g.getcells(g.getrect())
layerindex = g.getlayer()
collideship = []
popseq1 = []
popseq2 = []
g.addlayer()
g.setname("Ship collider space")
g.putcells(shippattern)
box = g.getrect()
g.select(g.getrect())
g.flip(1)
# For perpendicular collisions
flipship = g.getcells(g.getrect())
g.addlayer()
g.setname("Ship evolving space")
g.putcells(flipship)
g.addlayer()
g.setname("Collisions")
g.setlayer(layerindex + 2)

# Find the spaceship period
shiphash = g.hash(g.getrect())
period = 0
while True:
    g.run(1)
    period += 1
    if g.hash(g.getrect()) == shiphash:
        break
    if period > 500:
        g.exit("Period is too large! Are you sure the pattern is a spaceship?")
        
g.reset()
shipseq = [0] * period
def clear_layer():
    r = g.getrect()
    if r:
        g.select(r)
        g.clear(0)
    return

# Checks if two spaceships interact.
def interact():
    popseq = [[0] * 10] * period
    for j in range(10):
        for i in range(period):
            g.run(1)
            popseq[i][j] = int(g.getpop())
    notequal = False
    for j in range(10):
        for i in range(period):
            if popseq[i][j] != shipseq[i]:
                notequal = True
    if notequal == False:
        return False
    else:
        return True
    g.reset()
    
# Enumerating collisions
def putcollision(orientation, i, j):
    if interact() == True:
        g.reset()
        collision = g.getcells(g.getrect())
        g.setlayer(layerindex + 3)
        if orientation == 0:
            g.putcells(collision, 100 * j, - 100 * i)
        else:
            g.putcells(collision, 100 * j, 100 * i + 100)
        g.setlayer(layerindex + 1)
    g.reset()
    
def makecollision():
    g.setlayer(layerindex + 1)
    for i in range(period):
        g.setlayer(layerindex + 2)
        g.run(1)
        collideship = g.getcells(g.getrect())
        g.setlayer(layerindex + 1)
        clear_layer()
        g.putcells(shippattern)
        g.putcells(collideship, 500, 500)
        for k in range(period):
            shipseq[k] = int(g.getpop())
        for j in range(box[2] * 8):
            g.reset()
            clear_layer()
            # Perpendicular collisions
            g.putcells(shippattern, 0, 0)
            g.putcells(collideship, j - 3 * box[2], box[3] + 3)
            putcollision(0, i, j)
            # Head-on collisions
            g.select(box)
            g.flip(0)
            putcollision(1, i, j)
            
def deletelayers():
    g.setlayer(layerindex + 1)
    g.dellayer()
    g.setlayer(layerindex + 1)
    g.dellayer()
    
makecollision()
deletelayers()

Note that this makes a lot of layers, so hopefully you don't have too many open before running the script.

For larger ships, lines 45, 46, and 51 might need to be modified to allow later interactions.

Can someone make a script that generates collisions between a NW travelling glider and 2 upward travelling LWSSs? And before it generates those collisions it

Can someone make a script that does this?
Step 1: Generate all combinations of 2 upward LWSSs at a certain distance from each other (they can also be different phases from each other).
Step 2: Generate all combinations of a NW travelling glider colliding with all the combinations of the upward LWSS generated from the previous step.
Step 3: Filter the output of step 2 so the only combinations left from step 2are ones where a NW glider collides with an LWSS pair, then gets reflected into a NE travelling glider without any leftover ash.

Example of a combination of 2 Upward LWSSs + NW glider = NE glider:

Code: Select all

x = 9, y = 17, rule = B3/S23

Note that these are the most basic ruletables designed for single oscillators and that two cells being orthogonally adjacent causes undefined behaviour. Allowing oscillators to weave in and out of each other and exist on two different checkerboards, while preferable, would result in a much larger ruletable.

Is there a script that can turn a rule @TABLE into an @TREE?

Is there a script which automatically runs /attribute on objects in hauls that you submit? I can manually do it for under 30 bit still lives, but it would be good if there was a way to always get attributed for discoveries no matter their size instead of me manually reviewing each haul

I'd like a script that looks up all of the guns on Catagolue from period 15 through 999 and which are divisible by 3, and then returns the list of guns which both contain fewer than 10 cells that oscillate at period 3. This script is intended to find guns which have not yet applied p3 eaters.

Are there any scripts that can turn a non-isotropic range-1 rule into its strobing complement?

My memory of strobing rules is pretty vague at this point. A rule's "strobing complement" in general is two alternating rules, right?
