sprite (square) loops through its frames (colours) on collision with particles.[

but you could do a sprite collide with particle. this worked in 141 but not 156

pin the square to a separate sprite and as you rotate the sprite your square will rotate around it.

Glad to hear you got it sorted.

Are you thinking that solid should stop one solid crossing through another solid object?

Without seeing your capx I can't say where you are going wrong but have a look at the ghost shooter (tutorial demo) that comes with construct 2 - sounds like that should contain just what you are after. (also see the tutorial that it is based on)

Just re-install construct2 and it should bring everything back.

is it still called name.capx.autosave or have you removed the .autosave ? If you have not - do so (but be carefull that you don't overwrite anything you want to keep - might be a good idea to rename it to name.autosave.capx) and try again.

<img src="smileys/smiley9.gif" border="0" align="middle" /> before posting the above I thought I would just check and make sure that you needed to remove the .autosave extension - what I didn't do was to update construct 2 (this laptop is (was) running version 141 !) surprisingly construct 141 was not interested in loading files ending in .autosave but was happier about .capx (still had problems but that was due to version numbers). Anyway sorry about that. <img src="smileys/smiley9.gif" border="0" align="middle" />

another idea - assuming you have only vertical and horizontal blocks - just check see if ball angle is 0,90,180 or 270 and if so alter it a bit ?

(but I would still only run this check "once in a while" not every frame)

I would just go for something like

every 4 second

ball.bullet.angle=ball.bullet.angle+random(-0.2,0.2)

(play with time period and amounts)

this would correct any stuck balls but not be noticeable during normal game play.

Thank you for all these.

a better example ?
