Hi

I am new to scratch and stuck building a space invaders game.

The ship works and can fire at a sprite.

But When it hits the sprite nothing happends.

I have tried more than one solution without any luck so far.

Any advise would be great:

This is the alien sprite page:

<when green flag clicked>
<go to x sad )y sad
<show>

<forever>
<if><touching[ sprite 2
<hide>

I cant get the software to upload from work could be because im behind a proxy.

Fixed.

On Sprite 3, change it so that...

<when green flag clicked>
<go to x sad -144 )y:(133)Show

<when green flag clicked>
<forever if>
touching sprite two

<hide>

Thanks Babado,

So i needed the <when green flag clicked>

and also <forever if> not <if>

not sure why but it working.

Mmhm

The if block checks straight away, for example

Green flag clicked
if bla bla bla

That means it would check if it happend straight away. Forever if checks over and over again.

If=Straight away

Forever if=Anytime during the program
