 keeping score of the coins collected

Add a new object

This time we are going to add a Text Object

 object name: Scoredisplay

Font Size: 50

Click Bold

Text to display

Score :

Add your score to the top left

When you click preview, it doesn't show up because it is not on its own layer and we have the camera following the Hero

Select your score object and move it to the Front Layer

Test and save

Open up settings

Click Edit scene variables

Click add a scene variable

This is a scene variable so it is only going to work in this scene versus a global variable that will work throughout the entire project

Name the variable Score

The type we want is a number

We will start with 0

Switch to the events tab

Create a new event group

Name it score

Move your Hero coin collision into your Score Event Group

Now we are going to add an additional action to the coin collision

Add Change variable value

We are giong to use the variable that we just created

Score

The modification we want is to ADD

The value we want to use is 1

So our if then statement is

If the hero is in collision with the coin then delete the coin, play the sound and add one to the score variable

As you can see, nothing is happening on the screen, all the variable stuff is going on behind the scene.

We need to add an event that shows the Score variable on the screen.

Add a new event

We want the score to always be showing so we leave the condition blank

Our action is going to be Modify Text

The object  

Score

The text

"Score : " + VariableString(Score)

So what we are saying is After the text Score:, we are adding Score Variable printed on the screen

Click Add a variable

Create a new global variable called Score

make it a number

the number to start with is 0

Click Apply

So we have a scene variable and a global variable and they are both called score

Go to your events and find the event where the hero collides with the coin

find the action Change the variable Score add one

Double Click

Select Add or edit variables

Delete the Score Variable IN YOUR SCENE VARIABLE

Switch to your Gobal variables

Click on your Score Variable

Click Apply

Now when we look at the action, you can see that the Scene variable Score has changed to the Global Variable Score

It will not count the score on your screen because the Change the text  is still pointing to the old scene variable

Open up this action

Change the text from

"Score : " + VariableString(Score)

to

"Score : " + GlobalVariableString(Score)

Get a life!

Time for a life system

Add a new object

Heart

Create a heart with piskel

64x64

Apply

Add new object

TILED SPRITE not Sprite

Name it TileHeart

Choose File

Choose a file

Assets

Find your heart

Place your regular heart in the game somewhere

Place your tiled heart under your score

Move the TileHeart to the Front Layer with the score

 Go to events and create a new group

Name the group Health

You are now going to create an Object Variable

So a variable connected to an object

Add a new event

Object is Hero

Variable Value

Click the purple box to open your object variables

Add an Object Variable

Name the variable Health

The variable is going to be a number

The number is going to be 2 (we are starting with two lives)

So we are setting the variable to 2

We need to add the collision conditions to start taking away and adding lives

Hero is in collision with Heart

The action is going to be to change the Object Variable

So what we want to say 

If the hero is in collision with the heart then add 1 to the health variable of the hero

Test and save

In your events, add a collision so that if the hero touches the blade, the scene resets

Add Delete Heart to the action so it disappears

Add a new event

Condition is always

Object is the Tileheart

The action is the width

What we want to do is multiply the Hero Variable (health) by 64 so that the width shows a heart for each life (variable in health) 

Hero.Variable(Health) * 64

Test and save

Time to delete the hearts when the players dies

Add a new event in your Health section

If hero is in collision with killzone

The action is going to be the opposite action of when it collides with the heart so we want to change the variable of the Hero by subtracting one

Add a couple hearts to your game and test it.

Notice the hearts count up but when you die, it resets to two hearts

there is something in our game that is breaking it

When we collide with death, the game/scene is restarting

We need to delete the hero/killzone collision 

Create a new event (spawn point)

Add new object

Sprite

NO PISKEL THIS TIME

Apply

Set the spawn point at the start position

What we want to happen is the hero collides with the killzone, a heart is taken away in the variable and on the screen then the hero respawns

Under health, find your hero is in collison with Killzone

add another action

We want to change the position to the X and Y position of the object we created called Spawn
