Game Dev Journey

Three types of pickups: Ammo, Health and Stamina

Create a new scene called Pickup

With an Area2D as the root node

Rename it to Pickup

Add a CollisionShape2D

Add a Sprite2D

Set the Texture to

Assets -> Icons -> crystal_01i.png

Add a new RectangleShape2D for the Collision

Attach a new script to the Pickup node

On the very first line

mark the script as a tool script

so that we can view changes in the editor

Create a list of potential pickups

export them to the editor

You will now see a drop down

list of pickups in the inspector

Add a reference to the sprite node

so that we can dynamically change

the texture

Preload the textures so that we can

change them dynamically later

To update the icon in the editor

we can use the editor_hint function

within the process_function

This allows you to change icons in the editor

and see the change in real time

To update the icons during gameplay

we apply the same code

to the ready function

Remember to connect the body entered signal

so that the player can pick the item up

and it is removed from the game world

In the Player script

add custom signals

to update the ammo, health and stamina info

You can now see these signals

In the Inspector

Add variables for the pickup types

and their different amounts

Expand the node references

so that we can set up the GUI

Add variables for the

User Interface Elements

In the ready function

connect all the signals

using code

Regenerate health

&

Regenerate stamina

Within the process function

In the physics process function

update the code for sprinting

to reflect changes in stamina

Open the Input Map

Add actions to consume:

health pickups

stamina pickups

Assign keys such as 1 and 2

Now modify the input method

to handle the new actions

for drinking health potions

and drinking stamina potions

Add a new function to update

the interface to reflect how

many pickups the player has
