Hi guys,
I'm writing a simple ragdoll from scratch, but there's two thing acting weird that I'm unsure of.
1 - The joint limits I'm setting seem to have no effect, and;
2 - When in physics debug mode, all moving sprites have a line drawn from the sprite to the top left of the play area.
What's happening;
Once the "ragdoll" comes in contact with the floor, instead of just slumping over it rather explodes and the sprites go nuts all over the play area.
Check out the code below,
no external images/resources (I lied, it does use one png, one pixel by one pixel, white, I'll link it below), so just paste/run.
Note: When running my code, be sure to close the player a few seconds after things go crazy, as it looks like it's starting a hefty memory leak when things go awry.
