Need help with game code...

crazyfishdev

I want to have it so that when the actor is touched and you drag your finger in a direction and let go another actor spawns from the actor you touched in that direction. I have all the spawning down and am happy with it but I am unable to get the drag to work properly... any ideas? the main problem I'm having is that i don't want it to spawn if not a real drag but rather a tap.

The trick is to record the starting X&Y points of the touch. Then, upon release, calculate if the release location is far away enough.

Game Attributes...

• game.startX
• game.startY
• game.releaseX
• game.releaseY

If touch is pressed...
change game.startX to mouse.X
change game.startY to mouse.Y

if touch is release
change game.releaseX to mouse.X
change game.releaseY to mouse.Y
...if game.releaseX is greater than game.startX + 25
or... if game.releaseX is less than game.startX - 25
or... if game.releaseY is greater than than game.startY + 25
or... if game.releaseY is less than game.startY - 25
... run behaviors
otherwise... play error sound

This is just a rough outline. I didn't test it, but I think that could be the solution you're looking.

If you open GameSalad and click on the "New" plus button and then search for "swipe" or "drag," you'll see some good demos.

crazyfishdev

kk thanks... maybe there will be some new ones but when i looked before they all used 2 actors and i want to use only one to do it

@crazyfishdev I just modified the "simple swipe direction finder" demo and it worked great. It uses a single actor (instance) to detect the direction of the swipe.

There's also this @tshirtbooth video:

thanks I knew he did a video and went to look and i couldn't find it! thanks a ton!

crazyfishdev

alright... after watching the video I have run into a few potential problems... can it still recieve touch if another actor is above it? I have an actor on top that i would need to works well as as having the touch work...

crazyfishdev

i solved it nvm...
