To do this, insert a negate block (it's in the Numbers & Text category, Math sub-category) to the field where Ship Speed would go, then replace Ship Speed inside the negate block. Because positive speed values move an actor to the right, we have to use a negative value to make the actor move left instead. Once we have our second x-speed block with the Ship Speed inside of it, we need to make a slight change to have the Ship move left. You can use this to quickly copy a whole stack of blocks! If there are other blocks nested inside of the one you drag, they will be duplicated as well. Tip: To easily duplicate a block, hold down ALT and click-and-drag the block you want to duplicate. We now need another 'set x-speed to for ' block. Get another Control is Down block and set it to left.

Step 58: Now we need to set up what happens when the user presses the left key instead of the right key.

Snap the otherwise if block under the if block inside the Always Event block, as shown. Step 57: Next, go to the Flow category, Conditions sub-category in the Palette and drag the otherwise if block over to the work area. Step 56: Click on the empty number field in the set x-speed to for block, select Attributes in the pop-up dialog, and choose the one we just created, Ship Speed.Īs you would expect, the block will appear in the field.

We’ll show you how to set its value later when we complete this Event. Now you’ve got a blue block for the Ship Speed Attribute that you can set to different numeric values. In the dialog that appears, we will give our new attribute a Name of 'Ship Speed' and set the Type to 'Number'. To do this, let's click the Attributes category on the Palette, then click the Create an Attribute button. By doing this we won’t need to edit the speed value directly on the block in our Event every time we want to tweak it. Step 55: We now need to create an Attribute that we can use to adjust the value for x-speed. Drag it over to the work area, and snap it inside the if block's empty space so it looks like the image below. This block will allow us to control the ship's speed. Step 54: Next, we need to go to the Actor category of the palette and select the Motion sub-category and find the Set X Speed to for Self block, as shown below. Click the Control dropdown on the block and select Choose Control.įrom the dialog that appears, choose the right option, as shown.Īgain, the block will change to reflect this choice. We do, however, need to choose which control key to check.

Thus the if block inside checks (using a boolean) whether something is true constantly while the game runs to allow or disallow the code that it contains to run.Īs a result, our Control is Down boolean detects whether a control key is pressed or not to let code inside the If block run. Step 53: The Always block will constantly run through all the logic inside of it while the game runs. The Control is Down block will appear for us in the If block, as shown below. Mouse over the User Input category, and then choose the Control is Down block. a value that can be true or false, in Stencyl) in the block and a new dialog will pop up. Click the empty hexagonal field (this shape is always for a boolean, i.e. Step 52: Now we need to select the right block to go inside the hexagonal field in our If block. Step 51: We drag the if block into the Always block so it snaps in place. That block will appear in the work area where you first right-clicked. Right-click anywhere in the workspace area, mouse over the Place a Block option, then over the Flow category, then click on the if block. Step 50: This time, rather than dragging a block over from the Palette, we’re going to use the Block Picker. The following block will appear in the work area: To start, click the + Add Event button in the Events pane on the left, select Basics, and then choose When Updating from the three options shown. To do this, we need to specify what happens when the player presses certain keyboard keys AND what happens when the player isn’t pressing anything. We’re going to create an Event that will allow us to move our Ship both left and right in the scene by pressing keyboard keys. Step 49: What we are looking at is Design Mode again, this time for the Ship. Now that we’re in the Actor Editor and can edit our Ship, click the Events tab. Step 48: Click on the Dashboard tab, then on Actor Types, and select our Ship Actor Type. We've added an Event to the scene to play our music, now let's add an Event to our player's Ship so they can move it around! Comments Crash Course 2: Invaders - Part 8
