Variable and put in the name; this should give you a checkmark, meaning it knows what you are talking about. From the A != B output, attach a Destroy action to the right-hand side of the Compare Objects action by right-clicking and navigating to New Action | Actor | Destroy. Connect the Target connector of Destroy action to Instigator of the TriggerVolume_0 Touch event. Create an Int variable with a Var Name property of baseHealth that will be initialized with the value of 10. After the
input of the top Object action. Connect the Value connector to a new Object variable with no value. Create a Destroyed event by right-clicking and navigating to New Event | Actor | Destroyed. Connect the Out output of the event to the In input of the bottom Object action that sets the TurretTarget variable to nothing. Next, create an Attach to Event action by navigating to New Action | Event | Attach to Event. Under Attach to Event, connect the Turret Target variable to Attachee connector.
code window will come up. Fill that window with the following code://Import events so that we can have something happen every frame import flash.events.*; //Add an event to happen every frame stage.addEventListener(Event.ENTER_FRAME, Update); function Update(evt:Event):void { // Every frame we want to set the variables to // what we set them in Kismet cash.text = "$" + String(playerCash); // The wave number that we are at hudWaveNumber.text = String(waveNumber); // The times an enemy can hit our
yet. We want to make the AI (Artificial Intelligence) such that upon reaching our base he destroys himself, damaging our base. His death will decrement our base's health, and upon reaching 0, we will conclude the game is over. Now, we finally get to use those trigger volumes we created in the first section. In Kismet, go back to the Player Spawned event we created previously, and in Properties, give it a Var Name of Player. Exit out of Kismet and go into the editor. Select the Trigger
output. We want to make sure that the object that collided with the middle of the level is an enemy and not the player. We need to make a comparison to make sure it isn't. (New Condition | Comparison | Compare Objects.) Then, hook it up to the Touched output. Connect the Instigator output of the TriggerVolume_0 Touch event to A. Now we could draw a line to the Player variable I just made for B, but instead, we'll right-click and create a Named variable by navigating to New Variable | Named
