differential scrolling

sebmacfly

It's me again, lol... Sorry for asking so much questions! :S

I would like to make differential scrolling in my game... (it's a top view game)...
On the ground, sometimes we can see big holes... and i just want to see a second ground in that hole, that second ground, have to move a little easier than the first ground, to make a differential scrolling effect...
I don't know if i'm asking good, sorry for my english :S

I think sebmacfly is talking about a parallax effect. Some beginning info is here:

Also the Basic Shoot Em Up sample project (included among the templates under New Project) has a slow-scrolling background you might be able to use. There may be some more sample projects floating around somewhere.

cool, thank you, yeah, it's parallax effect... in french is "Scrolling différentiel"

I found that in your link :

I haven't done this yet, but I think parallax scrolling would be something like this...

Create a game variable... Speed

Rule for actor - If Right Arrow Down, Accelerate toward 0° at (speed)
Rule for background - If Right Arrow Down, Accelerate toward 0° at (speed)
Rule for far background - If Right Arrow Down, Accelerate toward 0° at (speed)/2
Rule for really far background - If Right Arrow Down, Accelerate toward 0° at (speed)/4
Rule for foreground - If Right Arrow Down, Accelerate toward 0° at (speed)*2

Yeah...do a search for "parallax" in the forum and on the support section. There is a lot of stuff on that. Also...layers are in your scene settings (upper right tab...on the left side of the work area)...to organize the z order of elements on the screen and whether they move with the camera or not.

PS:
Your english is good!
