What do you mean by a spawn engine? What does it do?

ToyinRocks

it spawns enemies and collectibles across a scrolling platformer

ToyinRocks

(i also played your games)

Do you need them to despawn off screen as well, and then re-spawn at the same spot if they do despawn?

ToyinRocks

yes

ToyinRocks

and d I have something for special collectibles

when green flag clicked

forever

if <touching [ v] ?> then
forever
broadcast [ v]
end
endend

(or this would go into an existing script If it didn't mess anything up)

i dont know what endend is

Well…… I suppose you could draw a huge square covering the whole screen, make it invisible (using ghost effect), and then have some script where object spawn points are touching the screen as it is being scrolled in?

There's probably a better way than that, I am sure.

ToyinRocks

i know how that would work

If you mean spawning entities at a certain spot, this should work

when green flag clicked
hide
reset timer
forever
if <((a) mod (timer)) = [0]> then
create clone of [me v]
end
end

when I start as a clone
show
forever
move around, do stuff, idk just move around do whatever::motion
if <touching [edge v] ?> then
detect if too far off edge::custom
end
end

define detect if too far off edge
set [variablex v] to (x position)
set [variabley v] to (y position)
go to x: ((x position) + (5)) y: ((y position) + (5))
if <not <<((x position) - (5)) = (variablex)> or <((y position) - (5)) = (variabley)>>> then
delete this clone
end
go to x: ((x position) - (5)) y: ((y position) - (5))

This spawns a monster every a seconds at the coordinates of the thing being spawned. The 5's in the custom block definition are if the monster moves 5 pixels at a time.

For a scrolling platformer, move the spawner and the monsters along with the level.

If you want to make it so that it spawns a monster if there is no monster yet, change the condition from if a mod timer = 0 to if clone? = 0, where ‘clone’ is a variable that changes to 1 when a clone is spawned, and 0 when a clone is deleted. If clone is 1, it will not spawn, and will change back to 0 upon deletion of the monster. If you want a three second cooldown before a respawn, use

forever
if <(clone) = [0]> then
reset timer
wait until <(timer) = [3]>
create clone of [me v]
set [clone? v] to [1]
end
end

Also, if the spawner can't move further along, make sure to stop the spawner.

define Enemy X:(X) Y:(Y) Type(Type)
set [x] to (X)
set [y] to (Y)
set [type] to (Type)
create clone of [myself]

Enemy X:((pick random (-100) to (100))  Y:((pick random (-100) to (100))

when I start as a clone
forever
AI Loop
go to x: ((x) - (scrollx)) y: ((y) - (scrolly))
end

ToyinRocks

do you guys use states in your projects?

What’s a state (I don’t know scratch terminology lol)
