setTerminalSpeed and negative acceleration #101

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What version of Rokon are you using?

Trunk (2.0.3).

Please provide any additional information below.

Currently, setTerminalSpeed takes 2 values, one for X and one for Y. But that 
means the X is only capped on one end (say 40), so when you accelerate in the 
other way (with accelerateX(-10) for example) there's no limit to the speed 
increase. Ideally, the terminal speed value should be absolute, so it should 
apply to the negative value as well (since negative acceleration is just 
acceleration in the other direction).

Fairly reasonable, I'll look at it, 2.0.3 has to be released today - this might 
not be in it

it's kind of a misspelling bug

if(useTerminalSpeedX && ((accelerationX > 0 && speedX > terminalSpeedX) || 
(accelerationX < 0 && speedY < terminalSpeedX)))

should be 

if(useTerminalSpeedX && ((accelerationX > 0 && speedX > terminalSpeedX) || 
(accelerationX < 0 && speedX < terminalSpeedX)))

in Sprite.java onUpdate()
