Direct Movement Method: block -1

Новая страница

'''Object Repulsion''' is the act of repulsing or repelling an object. Listed below are two methods of replicating this effect in [[Scratch]].
{{tip|Please remember to adjust the scripts shown in this tutorial as necessary to best fit a [[project]].}}

==Velocity Method==
The Velocity Method uses the following scripts to automatically make objects change their X and Y Velocity based upon their position. This script can go into any object that is being repelled. This method is more advanced than the next method, however this method is better in ''most'' situations.

{{note|Adding this will make the sprite move.}}

<scratchblocks>
when green flag clicked
go to x: (0) y: (0)
set [y speed v] to (0)
set [x speed v] to (0)
forever
if <([abs v] of (([x position v] of (Sprite1 v)) - ([x position v] of (Sprite2 v)))) < [50]> then
if <([x position v] of (Sprite 2 v)) > (x position)> then
change [x speed v] by (-0.1)
end
if <([x position v] of (Sprite 2 v)) < (x position)> then
change [x speed v] by (0.1)
end
end
if <([abs v] of (([y position v] of (Sprite1 v)) - ([y position v] of (Sprite2 v)))) < [50]> then
if <([y position v] of (Sprite 2 v)) > (y position)> then
change [y speed v] by (-0.1)
end
if <([y position v] of (Sprite 2 v)) < (y position)> then
change [y speed v] by (0.1)
end
end
end

when green flag clicked
forever
if on edge, bounce
change x by (x speed)
change y by (y speed)
set [x speed v] to ((0.98) * (x speed))
set [y speed v] to ((0.98) * (y speed))
end
</scratchblocks>

An example can be seen [[projects:1346516|here]].

==Direct Movement Method==
The Direct Movement Method uses the [[script]]s below to move and rotate based on its position. This method is basic, but very effective in doing its job.

{{note|This script can only be used in one [[sprite]] at a time unlike the velocity method.}}


<scratchblocks>
when gf clicked
go to x: (0) y: (-1)
forever
if <(distance to [Sprite2 v]) < [50]> then
point towards [Sprite2 v]
move (-10) steps
if on edge, bounce
</scratchblocks>

An example can be seen [[projects:1346517|here]].
