Terrible Tree Trouble

Alright, I am beating my skull over this problem, and I just can't figure it out.

I'm making a tower defense type game, and you can build towers on any tree on the map. I put in my tree sprite, and control-drug the tree to create multiple yet identical trees on the map.

I then made it to where when the player avatar collides with a tree, it turns to 75% opacity (to show that tree is activated) and turns a buildable boolean to "true." I then made it to where when the player avatar is no longer overlapping "tree," opacity is set back to 100% and the boolean becomes "false."

You already see what I didn't, right? If you walk from one tree directly into another tree, BOTH trees activate because I never technically stopped overlapping "tree." In fact, if I don't actually leave the forest, and I walk from tree to tree, I can "activate" 20 different trees if I want, and none of them go back to 100% opacity because I never stopped interacting with "tree." I need to make all of the trees individual instances so when I move from tree to tree the boolean and opacity resets for the tree I just left.

Does this make sense?

You could store the UID of the current tree, Pick all, and then do a foreach on the trees, resetting the values UNLESS the UID is the "current" one - turn those values on.

I thought I would have to use the UIDs for this as well, but all the commands I tried were wanting a specific UID instead of a range. Would you mind elaborating a bit more on what you mean? I think you might be on to something here, but I am unclear how to do the first couple of steps you outlines. Thank you so much for the help. I really appreciate it.

See event #9.

Thank you very much. I have been at work all day so I didn't get to reply before now, but I really appreciate your expedient response. I will work on this problem tonight based upon the information you provided.

I wish I could have replied to this without bumping the thread since it is such a focused issue. Sorry about that. :\</p>

The link to the capx isn't working. I think the hosting site is having DNS issues or something. I'll try again later. Thanks again. I really appreciate it.

Change .ZIP to .CAPX.

Thanks for the blackhornet. The code worked brilliantly for solving the majority of the problem, but now the last tree touched won't revert to 100% opacity when I leave the trees. I tried adding an additional condition for "when player is no longer overlapping tree, set opacity to 100%." That didn't solve the problem.

You got me really close though. Brilliant. I certainly appreciate it very much, and the extra effort you put into re-posting the link since the initial link was dead. Kudos sir. Let me know if there is anything I can help you with.

mmm I usually just Force a 'For each "tree condition on stuff like that and it works fine for me...have you tried that?

Try putting the trees in a Family then add an extra condition "For Each->(TreeFamily)....

that usually works for me....

Its not usually necessary but sometimes FORCING the condition works more consistantly

I'll try forcing it and see if it works. Hopefully the conditions don't press charges.

A-HA! I fixed it by slightly modifying the last .ZIP blackhornet sent.

Player is not overlapping tree

   Trigger once while true > Tree opacity 100%

This is what the functionality looks like for anyone in the future who stumbles across a similar problem. Thanks for all the help guys!

I believe this would work as well:

Every tick: Set tree opacity to 100

Player is overlapping a tree: Set opacity to 25

No need to hassle with uids or loops :-)

That doesn't work for the same reason that my original couple of simple ideas didn't work: there might be 30 trees on the map, but there is really only 1 "tree." You have to use the UIDs to distinguish between different instances of trees in order to individualize each tree, or else the opacity will be set to 75% for each consecutive tree you walk into without it reverting to 100% until you aren't touching ANY trees.

You just end up with half of the trees being transparent that way. :)
