scratch challenge #2

i still don't have anything to do so i went and did challenge #2. did you know that if you right click on the script you can duplicate it, it makes it so much easier.

scratch challenge #1

yeah, i know i'm supposed to do all the tutorials before i do the challenges but since you need to be at school to access the V drive and i have nothing better to do i decided to attempt one of the challenges.
the challenge was to make the sprite change directions when it hit the edge of the screen. i hope the picture explains what i did because when i try to explain it in words i end up confusing myself.

scratch- gliding

i kinda taught myself this witout the tutorial while mucking around so i thought 'well why not blog it so i don't have to do it later' so here is what i found out.
to glide you get the 'when green flag clicked' button to start off. then you get the 'glide whatever seconds to X:whatever Y:whatever' button from the motions section. you then click the boxes next to the X position and Y position at the bottom of the motion section and some rectangles will appear in the screen where your sprite is. you drag your sprite to where you want it to glide to and take note of the coordinates of the X and Y. in the 'glide' button you type the coordinates of the X and Y of where you want to glide to. in the 'glide' button you also type how many seconds you want it to take to get to the spot where you're gliding to.

scratch-change colour

to change the colour get a 'when space key pressed' button from control and add a 'change colour effect by 25' from looks and press the space bar and your sprite magically changes colour.

scratch-animate it

to animate your sprite you click on the costumes tab and copy your sprite and edit it and press okay. then you go back to the scripts tab and get the button 'when green flag pressed' and then add a 'forever' button. go to the looks and get a 'switch to costume' button and select the altered costume. get a 'wait 1 second' button and then a 'switch to costume' button but select a different costume and just keep repeating this until you run out of costumes. you press the green flag to watch your sprite become animated.
