Attacks

To inflict acts of violence on the monsters, we'll add in a sword for our player. I'm using the Lavish Sword...

Add it to the game, but don't drag it into the scene; we'll be adding it using events instead.

Attack Button

We'll need a button to trigger the sword attack. I'm using the A button...

Drag it into the scene and set the layer to GUI. Your scene should now look like this...

Attack Event

Whenever the A button is pressed, we want...

  1. Sword should appear in the direction the player is facing.
  2. Sword should remain for a fraction of a second.
  3. If any monsters touches the sword, the monster should be deleted.
  4. There should be a slight delay before the player can attack again.

We'll start with a new group event, and name it Player Attack.

Add a sub-event, and for condition, select Mouse button pressed or touch held and choose the Left mouse button. Add a second condition in the same sub-event, this time select the A button and choose cursor/touch is on object.

For the action, select the Sword and choose Create an object. The X and Y position doesn't matter, as we'll be changing it in a separate action, so just set them to zero.

We'll also need to make the sword a little larger, so add a second action, select the sword, and set Scale to 2.

Attack Direction

Next, we need to determine the direction that the player is facing, so we'll need to add 4 sub-events. These sub-events will check which animation the player is currently set to.

For the first condition, select the player and choose Current animation. Set the sign to = (equal to) and value to 0. For the action, select Value of scene variable, set the name to playerDirection, and set the value to 90.

In the sprite I'm using, animation 0 is a downwards movement, hence the playerDirection is set to 90 (south). You may need to use other values if you are using a different sprite.

Repeat for all 4 animations / directions.

Position and Rotate Sword

Select the Player Attack event and add a sub-event to that.

For this new sub-event, leave the condition empty. For the actions, select the Sword and choose Put the object around another. Choose the player as the center object. For distance, choose 50. For angle, click on the Expressions button, select Value of scene variable, and provide the name playerDirection.

Add a second action, select the Sword and choose Angle. Set the sign to = (set to) and the value to Expressions, Value of scene variable, and playerDirection.

Remove Sword After Delay

To remove the sword after a short delay, we'll need a timer. Add a new action to the Touch or mouse down event, select Other Actions and choose Start (or reset) a scene timer. Give the timer the name "swordDelay".

Select the Player Attack event and add a sub-event to that. For the condition, select the Other Conditions and Value of scene timer. Set the timer name to "swordDelay", and time in seconds to 0.3.

For the action, select the Sword and Delete the object.

Delay Before Next Attack

To impose a short delay after each attack, add a new condition to the Touch or mouse down event.

For the condition, select Other ACtions and Value of scene timer. Set the timer name to "swordDelay", and time in seconds to 0.6.

Removing the Monster

To remove the monster when the touch the sword, add a new sub-event under Player Attack. For the condition, select the Sword, Collision, and choose the Goblin. For the action, select the Goblin, and choose Delete the object.

Events Summary

If you have added all the events correctly, it should look something like this...
