drawing - Ball to brick collision in c# -

-

i writing program has ball moving around picturebox , have set of bricks @ top of picturebox.

i have used array location of bricks using:

int[,] bricklocation = { { 0, 0 }, { 30, 0 } }

i have used drawrectangle construct each brick within picturebox. exist within timer1_tick event. ball drawn, picturebox cleared , x , y coordinate change.

when ball "collides" brick, want way in brick disappear because there brick behind it.

[brick0]

[brick1]

at moment, code collision between ball , brick1 is:

if ((yball > bricky) && (yball < bricky + 25) && (xball > brickx) && (xball < brickx + 80))             {                 yballchange = -yballchange;             }

where xball, yball x , y coordinate of ball , brickx , bricky coordinate bricks.

so when ball coordinates within bounds of brick1 y-direction change.

is there way in can redraw [brick1] in new position no size eliminate there can collision between ball , [brick0]? or there else do?

javascript - How to synchronize the Three.js and HTML/SVG coordinate systems (especially w.r.t. the y-axis)? -

i'm combining 3d content three.js html , svg content. three.js cssloader pretty job synchronizing placement of html , svg content in 3d world. but svg/html coordinate systems 'left-handed', whereas three.js coordinate system 'right-handed'. means y-axes reversed. in svg/html, y / top goes go down screen, , three.js uses more standard mathematical convention of y going down go down screen. i have continually convert 1 other, pretty error prone. know not first run (for example, look here ). has come general solution? here's tried: do in object3d .scale.y = -1 . may suspect, turns out disaster. turns inside-out, , don't try put camera in there. do in object3d .rotate.x = math.pi . more promising, z axis no longer consistent html concept of z-index. still, i'm using now. in html, don't use top , use bottom . in svg , inside <g transform="scale(1, -1)"> inside <g transform="translate(0, imageheight)"> . h...
