Adding a New Potion

このページ中:

To help counter the damage that is done by the monsters in Action RPG (ARPG) the player can purchase and consume potions. Currently, there are two potions in ARPG that a player can use, a Health Potion that restores the player's health and a Mana Potion that restores the player's mana. In the following How-To, we will take a look at creating a new potion that will restore the players health and mana.

Steps

  1. First, locate the Potions folder in the ARPG project.

    Since ARPG uses the Asset Manager, all potions that the player will use must be placed in the potions folder or they will not show up in the store or players inventory.

  2. Next, right-click in the Content Browser and from the displayed list, select the Blueprint Class option.

  3. From the Pick Parent Class window, locate the All Classes section and input GA_PotionBase into the search box and click on GA_PotionBase.  Then click Select to create the new asset.

  1. Name the new potion GA_DeathsDoor.

    The GA in GA_DeathsDoor stand for Gameplay Ability.

  1. Now that we have the Gameplay Ability part of the effect which controls the visuals next we need to create the Gameplay Effect. The Gameplay Effect controls the values that are applied to the player's health when the potion is consumed. To do this, right-click in the Content Browser and from the displayed list, select the Blueprint Class option.
