firepawz_

im working on a scratch remake of the king fight for deltarune and there is one attack where he moves a box that the player is suppost to stay inside but when it moves the player just goes right through the box anyone know a way to keep the player inside it?

Can you share your project so people can see the problem and are then able to suggest ways to fix it for you?

Hi firepawz, this the solution I could come up with:

Note: all of this has to be done in your heart sprite
1- Create this local variables.

 

(xpos)
(ypos)

2- Add this script:

when I receive [enemy turn v]
set [ypos v] to [0]
set [xpos v] to [0]
repeat until <not <[(turn)] = [enemy]>>
    go to x: ((xpos) + ([x position v] of [Sprite5 v])) y: ((ypos) + ([y position v] of [Sprite5 v]))
end

3- Modify the script that makes the heart to move like this:

if <key [up arrow v] pressed?> then
change [ypos v] by (5)
if <(ypos) > [10]> then
set [ypos v] to [10]
end
end
if <key [down arrow v] pressed?> then
change [ypos v] by (-5)
if <(ypos) < [-30]> then
set [ypos v] to [-30]
end
end
if <key [left arrow v] pressed?> then
change [xpos v] by (-5)
if <(xpos) < [-55]> then
set [xpos v] to [-55]
end
end
if <key [right arrow v] pressed?> then
change [xpos v] by (5)
if <(xpos) > [45]> then
set [xpos v] to [45]
end
end

Another note: By doing this, it´s possible that your heart sprite might look like is being dragged by the black box (which is actually true, the heart is trying to keep up with the box coordinates). If that doesn't bother you, then you are good to go, otherwise you will have to create a new object , so the black box AND the heart can follow this new object, and since both are being dragged, boom, problem solved!

Let us know if you need more help!

No, no, no, no, there is a finest solution that you could make in two scripts:
· In the pushing sprite you do

when green flag clicked
forever 
  set rotation style [don't rotate v]
  if <touching [Pushed v] ?> then 
    point towards [Pushed v]
    set [Direction v] to (direction)
    broadcast [Push v]
  end
end

· In the pushed sprite you do

when I receive [Push v]
point in direction (Direction)
set rotation style [don't rotate v]
move (10) steps
if on edge, bounce

If you want you can change the block "Set rotation style" to whatever you want

Sqperdoo sorry but, this script seems to be trying to keep the char outside the box, the char is suppost to stay inside the box, not outside

You have to keep in mind that the title you wrote says “how to PUSH a sprite”, but at the end you don't need anything to be pushed (if I understood correctly)

Sqperdoo is giving you the solution the title is asking for (push a sprite with another sprite).

Please give it a try with the solution I suggested, hopefully it is what you need. If it is not, let me/us know, so we can try something different

For the box your best bet might be to use the distance to block. If the player moves and the centre of the box goes above a certain distance from the player the box needs to move as well.

Then use the scripts above to move the object that the block pushes. Do this via broadcasts rather than forever loops so the scripts stay in sync.

There should be an option for you, as the owner, to close a topic after 24 hours. I think it appears at the bottom of the topic thread.

Despite the small chance that you will see this message, you have just necroposted. I know you are new to forums in general, so it is not your fault you don't know that what you just did is a criminal offense. If you reply to a topic, it gets pushed to the top of the forums. But this is a really old topic so nobody cares about this and people find this annoying.

tl;dr no replying to old topics it's bad
