Crash Course 2: Invaders - Part 6

Part 6: Creating a Scene

Step 32: Click Scenes in the Dashboard, then we need to click the dotted line box to create a new Scene.

Step 33: After we hit that button, a dialog (shown) will pop up that lets us set some basic parameters for your Scene. Note you can choose the size of your Scene either using Tiles (which will use the Tile Width and Height, as shown) or in pixels. In this case we’re using Tiles and will use the default values, as shown. Let's give it a name of "Level One", and then as usual, we click Create to get Stencyl to make our new scene for us.

Once we do, Stencyl will open up our new scene in the Scene Designer.

Scene Editor

Step 34: To keep things simple, we’re only going to add the background image we imported earlier rather than add any Tiles. Backgrounds are one of the layer types we can have in our scene. To add one, we need to click the small + icon in the Layers list. In there we select New Background Layer.

Step 35: The "Choose a Background" dialog box will appear for us, and we can click on our Stars background and then click OK.

Step 36: Notice that our new Stars background layer is higher in the list than the default "Layer 0"? This means that if we try to add anything to Layer 0 it will be underneath our Stars background! Clearly this is not ideal, so to prevent this from happening, let's move the Stars background to the bottom of the Layers list. We can do this by clicking the down arrow at the bottom of the Layers list while the Stars background is selected.

Now our intial setup of the scene is done, and the main window of the Scene Designer should look like the image below.

Step 37: We’ve got our Scene, so let’s test it. Press the green Test Scene button and after a few moments we should see our Scene appear in a browser.

If the Scene appears, everything is working, and we can move ahead. If not, we can get help by clicking on the Need Help button and then choosing an option in the dialog that pops up. Let’s keep going

Step 38: Click the Actors tab in the Scene Designer, in the Palette on the right. You should see the three Actor Types you created earlier.

Step 39: Now we want to place individual Actors in the Scene. When placing actors, they are put on the Layer that is currently selected. As a result, we need to remember to click on Layer 0 to select it as the current layer.

To place actors, we use the Pencil tool as shown below; select it now if it is not already active.

With the Ship selected from the Actor Type list, Layer 0 selected (and above the background layer!) and the Pencil tool active, move our cursor over to the bottom-center of the Scene and left-click once. The Ship will appear. We only want one Ship for the player to control.

Note that we want the Ship to be within the scene boundaries, so don't put him in the grey "out of bounds" area! Put him inside the scene like in the image below.

Tip: To place Actors at even intervals, hold down the Shift key, which will align an Actor with the Tile grid. You can make the grid appear by pressing the Show Grid button.

Step 40: Next, select the Enemy Ship so we can place a few in the Scene. We can use the Shift key to space them evenly as shown in the image below.

Tip: If any of your Actors don't appear on screen even though you placed them in the Scene, make sure you check the game window's (the viewport's) settings. Its Width should be 640 and Height should be 480. Click Settings and then Display to change this. If you place an Actor outside the bounds of the viewport, you will not see the Actors you placed in your Scene. Also, note you can make a Scene that is larger than the game's viewport. To allow the player to see and move to other parts of the Scene, you'll need to implement a camera and camera scrolling, but doing that is outside the scope of this Crash Course. You can read more about implementing a camera here.

Step 41: Now we have a basic, complete Scene. Make sure it works via the Test Scene button again. We should see your Ship at the bottom of the Scene and the five Enemy Ships hanging out near the top.

We've got our Actors and Scene set up, so now it's time to start learning how to use Stencyl's Design Mode. To start, we're going to add background music to our Scene.

Chuckderp there is a much easier way to do that, just right click on the background in the layers menu on the bottom right of the scene editor and check the box that says "Repeat scene".

I got this from multiple comments and messed around but....

For the small background in top left corner: Take away the background from the scene, and close the scene. It autosaves.
Go to your backgrounds on the dashboard and delete it. Make a new background, name it stars or whatever, and add a frame. HERE, ON THIS SCREEN, you have to change settings. The "Scale" dropdown must be changed to "1x" and the "Resize Method" must be changed to "No smoothing". THEN you can add the space background with the "Add a frame..." in the top left. It will be much bigger and fit the default scene.

For the little tiny actors: Do what the steps say but BEFORE THAT do what I said above with the background. Change the scale to 1x and the resize method to no smoothing. After this you can add the frames and set the columns how the steps say.

Wow, this took so long to figure out, hope I helped someone!

My enemy ships were too small. I tried reloading with a different scale but that didn't work. Then I added the animation (Alien Grabber.png) as instructed. I clicked Edit Frame then Edit Image. I had to download the image editor before this would work. When the image came up in the image editor I changed the size of the image to a larger size (128X128) pixels. I saved it and then re-edited it back to the original size and saved it again. Now the images are the size they are supposed to be. I have no idea what THAT was about, but it worked.
