Hello all together, hope that someone helps.

I want to open a sprite, which is not visible before i make a collision, and this two times.
I use the following code:

loadimage(1,"one.png")
createsprite (1,1)
loadimage(2,"two.png")

if button = 1 and getspritecollision (mouse with sprite one)
createsprite (2,2)
setspriteposition(2,x,y)

This works fine, but if i want a collision with sprite two and there create sprite 3, it doesn´t work.

I have found a method that works, but i don´t know if it is good.

i create the sprite three at the top of the code and set this one invisible and if i make a collision with the second sprite i make it visible.

I guess, there is a better way.

Thanks for hepl

The collision is probably still hitting sprite 1.
You have said what is happening to sprite 1 after the collision but if it's no longer needed then try deleting it or moving it offscreen.

Hello sprcoll,

can you send more code, so we can also compile? And can you explain, what you want to do with it in detail?
I see the possible error, that you may use getspritecollision outsite a loop - it's unusal and brings up the question, how this code should behave.

Instead of createsprite (2,2), just do createsprite (2)... If you need to keep track of the spawned sprite IDs then you'll need to set up a dynamic array to store the values as they are generated.

EDIT: Also, when you post a question, try to make the subject relevant to the question. That way people can find it when they use the search facility

createsprite (2,2) should not be in a button condition without deleting the sprite first.

You only need to create it once, so create all your sprites outside of your loops at the beginning.

Right

if all you want is visibility on the collision, then that is all you need to do to the sprite you already created, not recreate the sprite.

If you want to check that collision only x times then use a variable to count it and add that condition to the collision check

Thanks to all of your help. Here is a little bit more code

loadimage (20,"mouse".png)
createsprite (20,20)

loadimage (21,"menu_1".png)
createsprite (21,21)

loadimage (22,"menu_2.png")

loadimgae (23,"menu_3.png")

do

if button = 1 and getspritecollision (20,21)
createsprite (22,22)
setspriteposition (22, 1300, 100)
endif

Until here it works.

if button = 1 and getspritecollision (20,22)
createsprite (23,23)
setspriteposition (23,1300,200)
endif

Sync()

If i compile this, i get a massage that sprite 22 doesn´t exist but i have this one created before.

YES

That is what I'm talking about, create the sprites first, then change them under conditions in your loop.
