How do I…
I’m trying to build a tower placement validation system. I almost succeeded!
1 When the user taps on the build area.
2 Fingerprint object is moved to cursor area (its normally invisible)
3 This is used to check the area is large enough for a tower to be placed.
4 If Fingerprint is in collision with another object or touching the do_not_build area. It will move the fingerprint around its original location to see if their is a valid location to place the menu.
What is the expected result
If the code finds a valid area it shows the build menu.
If it does NOT find a valid area the build menu is not shown.
What is the actual result
It works. Well it used to.
It fails if I click in the same invalid area twice. Not a double click.
Lets say i click inbetween the bushes. The menu is correctly not shown.
Then a second click in the same location shows the menu when it should not.
Related screenshots
this is showing a fail on second click. The black box is the fingerprint and you can see its in contact with a bush. The menu should not be showing in this instance.
Project files (optional)
So this code is a bit of a mess now because i have been trying many different ways to fix it. Also im not sure if its my code or a gdevelop quirk im not aware of.
