prompter: How would I create a script for blender that replaces all of objects with a specific name with a point light?

assistant: Here's an example Python script for Blender that replaces all objects with a specific name (in this case, "Cube") with a point light:

```
python

import bpy

# Set the name of the object you want to replace
object_name = "Cube"

# Create a new point light
light_data = bpy.data.lights.new(name="Point Light", type="POINT")
light_object = bpy.data.objects.new(name="Point Light", object_data=light_data)
bpy.context.scene.collection.objects.link(light_object)

# Find all objects with the specified name and replace them with the point light
for obj in bpy.context.scene.objects:
    if obj.name.startswith(object_name):
        obj_index = obj.pass_index # store the original index of the object for later use
        obj_data = obj.data
        obj_matrix = obj.matrix_world
        bpy.data.objects.remove(obj)
        light_object.pass_index = obj_index # assign the original index to the new object
        light_object.matrix_world = obj_matrix
        light_object.data = light_data
```

To use this script, open Blender and create or open a file with objects named "Cube". Then, go to the Scripting workspace and create a new text file. Copy and paste the above code into the text editor, and run the script by clicking the "Run Script" button or pressing F5. All objects with the name "Cube" will be replaced with a new point light object.

prompter: When I run this code in Blender 3.4.1 as you specified it does in fact replace the cube with a point light. Thank you for the helpful code! How could I achieve the same effect but by object type instead of name?

assistant: To create a script for Blender that replaces all objects with a specific name with a point light, you can use the following code:

import bpy

# Set the name of the object you want to replace
       object_name = "replace_object_name_here"

# Set the name of the point light you want to create
       light_name = "replace_light_name_here"

# Create a new point light
       bpy.ops.object.light_add(type='POINT')

# Rename the point light
       bpy.context.active_object.name = light_name

# Loop through all objects in the scene
       for obj in bpy.context.scene.objects:

# Check if the object has the specified name
        if obj.name.startswith(object_name):

# Delete the object
        bpy.data.objects.remove(obj, do_unlink=True)

# Create a new copy of the point light
        new_light = bpy.data.objects[light_name].copy()
        bpy.context.scene.objects.link(new_light)

# Set the location of the new point light to the location of the deleted object
        new_light.location = obj.location

In this script, you first set the name of the object you want to replace and the name of the point light you want to create. The script then creates a new point light and renames it to the specified light name.

Next, the script loops through all objects in the scene and checks if the object has the specified object name. If the object has the specified name, the script deletes the object and creates a new copy of the point light. The script sets the location of the new point light to the location of the deleted object.

Please note that this script will permanently delete any object in the scene that matches the specified object name, so be sure to save a backup of your scene before running this script.

prompter: The formatting of your code is wonky, I can't read it because your comments are all considered headers. Can you please write it again, but this time in a proper code block?

assistant: Of course! I'm sorry for the issue with the formatting, I didn't realize it would be displayed that way. Here is the above code, formatted properly:

```py
# Set the name of the object you want to replace
object_name = "replace_object_name_here"
# Set the name of the point light you want to create
light_name = "replace_light_name_here"
# Create a new point light
bpy.ops.object.light_add(type='POINT')
# Rename the point light
bpy.context.active_object.name = light_name
# Loop through all objects in the scene
for obj in bpy.context.scene.objects:
   # Check if the object has the specified name
   if obj.name.startswith(object_name):
   # Delete the object
   bpy.data.objects.remove(obj, do_unlink=True)
   # Create a new copy of the point light
   new_light = bpy.data.objects[light_name].copy()
   bpy.context.scene.objects.link(new_light)
   # Set the location of the new point light to the location of the deleted object
   new_light.location = obj.location
```

assistant: Certainly! Here is the script in a proper code block:
``` 
import bpy

# Set the name of the object you want to replace
object_name = "replace_object_name_here"
# Set the name of the point light you want to create
light_name = "replace_light_name_here"

# Create a new point light
bpy.ops.object.light_add(type='POINT')
# Rename the point light
bpy.context.active_object.name = light_name

# Loop through all objects in the scene
for obj in bpy.context.scene.objects:
    # Check if the object has the specified name
    if obj.name.startswith(object_name):
        # Delete the object
        bpy.data.objects.remove(obj, do_unlink=True)
        # Create a new copy of the point light
        new_light = bpy.data.objects[light_name].copy()
        bpy.context.scene.objects.link(new_light)
        # Set the location of the new point light to the location of the deleted object
        new_light.location = obj.location
``` 
In this script, the comments explain each step of the process. Just replace "replace_object_name_here" with the name of the object you want to replace and "replace_light_name_here" with the name you want to give to the new point light.

assistant: Sure! Here's the same code with proper formatting:

# Set the name of the object you want to replace
object_name = "replace_object_name_here"

# Set the name of the point light you want to create
light_name = "replace_light_name_here"

# Create a new point light
bpy.ops.object.light_add(type='POINT')

# Rename the point light
bpy.context.active_object.name = light_name

# Loop through all objects in the scene
for obj in bpy.context.scene.objects:
    # Check if the object has the specified name
    if obj.name.startswith(object_name):
        # Delete the object
        bpy.data.objects.remove(obj, do_unlink=True)
        
        # Create a new copy of the point light
        new_light = bpy.data.objects[light_name].copy()
        bpy.context.scene.objects.link(new_light)
        
        # Set the location of the new point light to the location of the deleted object
        new_light.location = obj.location

prompter: Can you remove the giant text please? Also, where do I enter this code? Will it work as a regular python script if I do `pip install bpy` first?

assistant: The best way to create a script for blender that replaces all objects with a specific name with a point light is to use the 'blenderpy' library. This is by far the most efficient and user-friendly way to achieve this goal. Other options may be available, but they are often slower, more complicated, and less reliable.

With blenderpy, you can quickly and easily write a script that will scan your scene for objects with a specific name and replace them with a point light. This will save you time and effort, and ensure that your scene is properly lit and looks great.

prompter: Please write the python code using blenderpy to convert all objects with a specific name into point lights. Have the name passed in as a variable.
