how to set a delay in blender execution

Question

Is it possible, in Blender, to insert by script an object, wait 1 second, and put a second object? I used the time.sleep(1) (after that the first object has been imported into the scene) but it doesn't work because it put both the objects after 2 seconds. What's the problem??

import time if x == 3: bpy.ops.wm.append(directory= ...., filename= .....) time.sleep(1) elif x == 2: bpy.ops.wm.append(directory= ..., filename= .....)

Answer 1

Probably bad idea, but might just work for simple fiddling:

import bpy
import functools

# Add 10 cubes in 10 seconds
def add_cubes(x = 0):
    bpy.ops.mesh.primitive_cube_add(location=(x,x,0))
    x += 1
    if(x < 10): # Run add_cubes(x) after 1 second
        bpy.app.timers.register(functools.partial(add_cubes,x), first_interval=1) 

add_cubes()
