Hey guys, was wondering/looking for a way to update the SpriteRenderer Sprite in runtime to a new texture. Is there a way for me to dynamically generate a new sprite class from a texture or just use a texture directly to update a SpriteRenderer. Any help is much appreciate!
import { Behaviour, serializable, SpriteRenderer} from "@needle-tools/engine";
export class TestRuntimeSprite extends Behaviour {
@serializable(SpriteRenderer)
public renderer: SpriteRenderer;
public texture: Texture;
start() {
this.renderer.sharedMaterial = this.renderer.sharedMaterial.clone();
this.renderer.sharedMaterial["map"] = this.texture;
this.renderer.sharedMaterial.needsUpdate = true;
}
}

Hi Danny! To update the SpriteRenderer sprite at runtime with a new texture dynamically, you can indeed leverage the existing code to achieve that. The key point is ensuring that the texture is applied correctly to the material of the SpriteRenderer.
Here’s the refined approach based on your code:
Make sure your texture is a valid instance of THREE.Texture.
Assign that texture to the map property of the sharedMaterial’s map.
Here’s how you can do that:
import { Behaviour, serializable, SpriteRenderer, Texture } from "@needle-tools/engine";
export class TestRuntimeSprite extends Behaviour {
@serializable(SpriteRenderer)
public renderer: SpriteRenderer;
@serializable(Texture)
public texture: Texture;
start() {
const newMaterial = this.renderer.sharedMaterial.clone();
newMaterial.map = this.texture; // Set the new texture
newMaterial.needsUpdate = true; // Notify the material that it needs updating
this.renderer.sharedMaterial = newMaterial; // Apply the new material to the renderer
}
}
Ensure that the texture you are assigning is already loaded. If you have further questions or need more details, just let me know!

Hi Danny! If the code doesn’t work as expected, there are a few things to check and an alternative approach you can take.
Steps to Check:
Ensure Texture Is Loaded: Verify if the texture is properly loaded before applying it.
Material Properties: Explore different properties of the Material, as different shaders may require specific settings.
Alternative Approach:
You can create a sprite directly from the texture instead of altering the existing material. Here’s an example:
import { Behaviour, serializable, SpriteRenderer, Texture } from "@needle-tools/engine";
export class TestRuntimeSprite extends Behaviour {
@serializable(SpriteRenderer)
public renderer: SpriteRenderer;
@serializable(Texture)
public texture: Texture;
start() {
// Create a new sprite from the texture
const newSprite = new Sprite();
newSprite.texture = this.texture;
this.renderer.sprite = newSprite; // Assign to the SpriteRenderer
}
}
Libraries:
Make sure you have @needle-tools/engine properly set up in your project. If you’re using any additional libraries for texture loading, ensure they are compatible with your version.
Feel free to follow up with any specific error messages or behavior you observe, and I’ll be glad to assist further!

Hi Danny! If the sprite isn’t updating or displaying correctly, it could be due to several factors in the setup within Unity. Here are some troubleshooting steps and best practices you can follow:
1. Check the Object Hierarchy:
Ensure that your SpriteRenderer component is correctly attached to the GameObject you are manipulating.
Verify that the GameObject is active in the hierarchy.
2. Texture Import Settings:
Check that the texture used is set to the correct import settings. It should be marked as a Sprite (2D and UI) in the texture’s import settings in Unity.
3. Confirm Script Execution:
Ensure the TestRuntimeSprite script is attached to the GameObject with the SpriteRenderer.
Make sure the start() method is being called properly. You can add debug logs to check.
4. Material Assignment:
Confirm that you’re not inadvertently overwriting the sharedMaterial in a way that causes it not to display. You might want to instantiate a new material instead.
Example Setup Code:
To ensure proper sprite updating, you might simplify it to only set the texture, as shown below:
import { Behaviour, serializable, SpriteRenderer, Texture } from "@needle-tools/engine";
export class TestRuntimeSprite extends Behaviour {
@serializable(SpriteRenderer)
public renderer: SpriteRenderer;
@serializable(Texture)
public texture: Texture;
start() {
this.renderer.sharedMaterial.map = this.texture; // Set the new texture
this.renderer.sharedMaterial.needsUpdate = true; // Update the material
}
}
Debugging:
Use console.log to check if your texture is being loaded and assigned as expected.
Ensure there are no other components or scripts affecting the visibility or rendering of the GameObject.
If you’re still encountering issues, providing specific details of your Unity setup or error messages would be helpful. Let me know how it goes!

Circling back this might be a bug, testing the same code using a Mesh renderer works, using image works as well but doesn’t seem to work using SpriteRenderer. I could also be doing something wrong as well but if someone can try to reproduce and let me know
Hi Danny! It sounds like you’ve isolated the issue effectively, indicating that the problem might be specific to the SpriteRenderer implementation. Here’s a suggestion to help verify and possibly reproduce the issue:
Steps to Reproduce:
Create a New Sprite in Unity:
Create a fresh Unity project or scene and add a GameObject.
Attach a SpriteRenderer to the GameObject.
Assign a Simple Texture:
Ensure you have a basic texture (like a solid color or a basic image).
Follow the initial steps with your TestRuntimeSprite code to assign this texture dynamically.
Debugging Output:
Use console.log to print which texture is being assigned, and check if it properly loads.
Confirm the start() method is triggered using debug logging.
Conduct Tests:
You can also try testing with different textures and ensuring all import settings are suitable for use with SpriteRenderer.
Suggest a Bug Report:
If you confirm the issue persists across different scenarios, it might be worthwhile to submit a bug report to the Needle Engine team with your findings, including specific setup instructions and version details.
If you manage to gather additional findings, I’m here to help analyze those!

Just circling back here, to report a potential bug. For now just going to use a mesh renderer but seems like SpriteRenderer isn’t working as intended. Some example pictures below to reproduce the bug. Also if I try removing the sprite the image wont render at all
To Reproduce:
Make a SpriteRenderer using circle, triangle, etc
Add the TestRuntimeSprite component
Assign SpriteRenderer and a test texture image
Image will be confined to the shape of the sprite
Removing the sprite will cause the image to not render
Hi Danny! Thank you for providing the detailed steps to reproduce the potential bug with the SpriteRenderer. Your observations are valuable and can indeed help in diagnosing the issue.
Bug Reporting Suggestion:
Collect Info: Document the exact steps you followed, the version of the Needle Engine, the Unity version, and any other relevant factors you noticed during testing.
Screenshots: Include the images you provided, showing the sprite rendering as intended and then failing when altered.
Contact Support: Reach out through the appropriate support channels for Needle Engine, often found in their documentation or support website. Provide all the details you gathered to facilitate the bug investigation.
Temporary Solution:
As you’re already doing, using a MeshRenderer seems like a viable temporary workaround until a fix is identified for the SpriteRenderer.
If you find anything new, or if there’s anything else you’d like assistance with, feel free to reach out!
