Stage: Application, Coordinates, and Display Objects · Editable example · Storage ID: pixijs-step-05

Goals and learning outcomes

Prerequisites

Prerequisite concepts: Style After Geometry, Object Transforms. Prepare the output files and observation records from Unit 4.

Key concepts and explanations

Creating Text

v8 Text can be configured with an options object containing text and style. Font and size affect text measurement and visual quality.

Update Costs

Changing a string may also update the text rendering resources. Avoid assigning the same content again every frame.

Practice setup

First check the execution scope guidance on the example screen. The following describes preparation for extending the assignment in a separate project. Implement the work yourself in an HTML and ES module project served by a separate local HTTP development server. Pin and record the installed pixi.js 8.x version.

The linked example is a starting point. It does not implement every task below. Complete work beyond its supported scope in a separate project.

Practice tasks

  1. Prepare day-05.js and index.html in the external practice project. Create a scoreboard with new Text({text:'점수 0',style:{fontSize:24,fill:...}}).
  2. Update text only when the score changes and compare line wrapping for a long Korean string.
  3. Save the output with the input condition Every frame, then run again with When the value changes. Expected: Unnecessary text update requests decrease. Compare this with the actual screen and logs, and record the actual result and causes of any differences in day-05-notes.md.

Predictions in this table are not measured results. Change one condition at a time and record why the actual result differs.

Completion criteria

Self-check

  1. Why can enlarged text look blurry?
  2. When would you consider BitmapText?
