I need a sensor script
I want my sprite not to go through walls or bushes so I put COLOUR SENSING in, but it took me an hour to make. I want a script that will bounce off the script, for e.g.
If touch top of bush
change y by 1
if touch bottom of bush
change y by-1
if touch left of bush
change x by-1
if touch right of bush
change x by 1
Help!! Plz!

Re: I need a sensor script
Just make an outline of a slightly different colour around each side of your bush, and use those as colour sensing.
However, that might not works so well if you bush isn't a rectangle. In that case, I can't help you all that well.
By the way, when you change x by -1, you have to make sure it's enough to counteract any opposite motion - are you sure it's enough?

Re: I need a sensor script
Try looking at this project's script, may or may not help. It uses single color sensing (the wall and the moving sprite are both only one color, so it looks more professional than making every side of a wall a different color. You could also adapt it to using <touching[

If touching bush...
check direction of player travel (you can use distance too or not) then adjust motion according to that, like a Pong paddle.
To do a round reflection, face bush towards player and use it's direction to set the new player direction (or bounce.)

Re: I need a sensor script
Simple solution: Make four sprites that are lines. (Make them stand out from the background) Two of them horizontal, two vertical. Tell them to go to the x and y position in the center of the bush. Now try a little trial-and-error using the change x by: and change y by: block to make your lines on the outsides of your bush. Now make your sprite you want to 'bounce' off the sides bounce if touching one of the lines. Finally, go to the 'walls' and make them set their ghost effect to zero. (forever is optional) Hope this helps.
