When you’re trying to open the extension, you want to make sure you’re using the [github.com](http://github.com) address and not [github.io](http://github.io).

The address you need should look like this:

hey! @richard. I’m once more asking for your help XP

so here is the problem

so I’m working on a Hitbox extension and I’m making a way to draw something where certain hitboxes are, like draw the outline of a hitbox called “bob”  
but i have been trying to only draw it if its in the screen and only the parts in the screen with the camera  
i have yet to find a way to do so  
here is the project

> **[Hitbox extension](https://arcade.makecode.com/12687-67304-43102-37807)**

@YuHayate all you need is to use the current camera on the scene. There are two properties on the camera object that are worth noting: camera.drawOffsetX and camera.drawOffsetY. Whenever you are drawing anything to the screen, just subtract those two numbers from the x and y respectively:

```typescript
const camera = game.currentScene().camera;
screen.fllRect(
    x - camera.drawOffsetX,
    y - camera.drawOffsetY,
    width,
    height,
    color
)

```

@YuHayate you can clear the screen by using the fill method: `screen.fill(0)`

`screen.fill(0)` doesnt work you have to do ` scene.backgroundImage().fill(0)`

blood isn’t against the rules; it really depends on the other content of the game!

Would you mind adding a link to your project? It will help with the debugging.

hey @richard! i wanted to know a thing or two here, first off in the math section theres the math block with the `sqrt(0)` but using the enum on that block you can change the number of inputs like if you select the `atan2(0,0)` option, i wanted to know if you can do that in an extension and if so was there a way to make is so that it doesnt just change the number of inputs but does something like every option of the enum leads to an other enum that might have an other enum after or not?
