arcade-text's Introduction

Text Sprite Build status badge

Usage

This extension allows you to create "text sprites" which are just sprites created with the visual appearance of text. All standard behavior and APIs for sprites apply to them. In addition, the Text Sprite extension has helpful blocks for working with and changing the appearance of text sprites.

Note that when unicode characters are in use, the font height used in text sprites will always be a multiple of 12px. Whereas otherwise we prefer to use multiples of height 8px or 5px fonts.

arcade-text's Issues

TextSprites and their Images remain in memory after being destroyed

I have been working on a project that uses Kittenbot's Meowbit, which has 2MByte spi-flash memory, which is a bit tight for the requirements by my client.

I wish to cut down on the memory usage after hitting the dreaded 021 error. I have limited success by setting all sprites to GHOST (0.6% reduction due to hitboxes as per heap snapshot).

My best hope is to free the memory contributed by TextSprites along with their images after initial use at the title screen of my game (2884/23516 per Summary with heap snapshot) but they never get freed.
