Displayed at the top in a larger font. It can also be a function that returns updating text. Can use basic HTML.</p></li><li><p>description: A description of the upgrade's effect. <em>You will also have to implement the effect where it is applied.</em> It can also be a function that returns updating text. Can use basic HTML.</p></li><li><p>effect(): <strong>optional</strong>. A function that calculates and returns the current values of any bonuses from the upgrade. Can return a value or an object containing multiple values.</p></li><li><p>effectDisplay(): <strong>optional</strong>. A function that returns a display of the current effects of the upgrade with formatting. Default displays nothing. Can use basic HTML.</p></li><li><p>fullDisplay(): <strong>OVERRIDE</strong>. Overrides the other displays and descriptions, and lets you set the full text for the upgrade. Can use basic HTML.</p></li><li><p>cost: A Decimal for the cost of the upgrade. By default, upgrades cost the main prestige currency for the layer.</p></li><li><p>unlocked(): <strong>optional</strong>. A function returning a bool to determine if the upgrade is visible or not. Default is unlocked.</p></li><li><p>onPurchase(): <strong>optional</strong>. This function will be called when the upgrade is purchased. Good for upgrades like "makes this layer act like it was unlocked first".</p></li><li><p>style: <strong>optional</strong>. Applies CSS to this upgrade, in the form of an object where the keys are CSS attributes, and the values are the values for those attributes (both as strings).</p></li><li><p>layer: <strong>assigned automagically</strong>. It's the same value as the name of this layer, so you can do <code>player[this.layer].points</code> or similar.</p></li><li><p>id: <strong>assigned automagically</strong>. It's the "key" which the upgrade was stored under, for convenient access. The upgrade in the example's id is 11.</p></li></ul><p>By default, upgrades use the main prestige currency for the layer.

The name to display for the currency for the upgrade.</p></li><li><p>currencyInternalName: <strong>optional</strong>. The internal name for that currency.</p></li><li><p>currencyLayer: <strong>optional</strong>. The internal name of the layer that currency is stored in. If it's not in a layer (like Points), omit. If it's not stored directly in a layer, instead use the next feature.</p></li><li><p>currencyLocation: <strong>optional</strong>. If your currency is stored in something inside a layer (e.g. a buyable's amount), you can access it this way. This is a function returning the object in "player" that contains the value (like <code>player[this.layer].buyables</code>)</p></li></ul><p>If you want to do something more complicated like upgrades that cost two currencies, you can override the purchase system with these (and you need to use fullDisplay as well)</p><ul><li><p>canAfford(): <strong>OVERRIDE</strong>, a function determining if you are able to buy the upgrade</p></li><li><p>pay(): <strong>OVERRIDE</strong>, a function that reduces your currencies when you buy the upgrade</p></li></ul></div></div></main><footerclass="VPDocFooter"data-v-6b87e69fdata-v-ef5dee53><!--[--><!--]--><divclass="edit-info"data-v-ef5dee53><!----><divclass="last-updated"data-v-ef5dee53><pclass="VPLastUpdated"data-v-ef5dee53data-v-7e05ebdb>Last updated: <timedatetime="2023-11-28T02:02:57.000Z"data-v-7e05ebdb></time></p></div></div><!----></footer><!--[--><!--]--></div></div></div><!--[--><!--]--></div></div><!----><!--[--><!--]--></div></div>
