### Re: My ongoing newbie questions

Jake: This code will make the object accelerate smoothley. newX, newY = -0.5*math.cos(-3) + vx, -0.5*math.sin(-3) + vy Ofcourse you can do something like this if you don't want any acceleration: //Move left newX, newY = vx -5, vy //Move right newX, newY = vx + 5, vy But when you do that, the veloci...

This is a cool concept! The problem is that it's hard to see what cells the items occupy. And the keys are too responsive

### Re: Using easing equations

These functions are definitely helpful. However I don't like how everything is based on strings. So I edited anim.lua to be more class based. anim.lua function anim.create( from, to, time, delay, eq, ... ) function anim:start() function anim:pause() function anim:callback( delay, func, ... ) functi...

I don't think Lua has a round function but this will do the same

Code: Select all

function math.round(x)
return math.floor(x+0.5)
end

Depends on exactly what but surely it's quicker just to do a table lookup, right?

### Re: No blend mode.

Alternatively you could just draw the quarters of the circles so no actual overlaying occurs. If it's an image you can draw the 'subsprite' (draws) of a corner of the circle.

I would prefer to do that because it seems safer to me.
