I plan to make a platform game in a world made of words and letters and wonder if it would be possible to get AppGameKit text to ineract with the physics engine, for example convert the text to sprites.

Sincerely,

Well, if you used sprites for text, then it can certainly interact with the physics engine.

The trick is how you do it.

One way might be to have individual images for each letter and create a sprite for each one, as needed, and then keep the sprite ids of words in something (easier in Tier 2 with structs and classes that let you use lists and arrays within them than in Tier 1 which does not let you put arrays in typedefs).

Another might be to create the word using basic text, then grab that segment of the display and create an image and a sprite from it and then remove the text and display the sprite.

Just a couple of rough, quick ideas.

But, there is no way, at present that I can think of, to make the text objects themselves interact with the physics system.

Your basic idea sounds interesting.

What if you just place blank/transparent dummy sprites over the text objects, and then activate physics on them, and then you sync the text's coordinates and rotation with the sprite coordinate for every loop.

In fact, in this way you could even smooth out jitters, by not updating the coordinates of the text object, if it just keeps jumping a little, as physics sprites sometimes do.

Text in AppGameKit is already sprites, technically

Otherwise, an easy way to solve this problem would be to make a sprite-sheet with letters, and assign them each sub image ids in order of the alphabet (1-26 + special characters). Then just clone sprites based on the value of the letter in the text string and clone the correct sprite.

"A boy"

A = Base Sprite (Font) ID of 100 + Shift (35, let's say that's enough to cover the alphabet plus whatever additional characters you need) + First Letter (a) = Iamge ID of 136
_ = Base Sprite (Font) ID of 100 + Space (27) = Image ID of 127
b = Base Sprite (Font) ID of 100 + Second Letter (b) = 102
o = Base sprite (Font) ID of 100 + 15th letter (o) = 115
y = Base Sprite (Font) ID of 100 + 25th letter (y) = 125

Hi there. My name is Dug. I have just met you, and I love you.
