Hi all.

Having issues with jumping. Currently using the command:

When i press the Up arrow sprite, the sprite moves up, then when i let go, it drops back down. Now, i want the sprite to JUMP, not FLY. I.e. when i press the up arrow, regardless of how many times i press it, it won't jump again until it hits the floor. Now, i've read the following post:

http://forum.thegamecreators.com/?m=forum_view&t=212989&b=41

And a moderator suggested doing the following:

You could check for collision below the players usual Y position. Like, make a floor from sprites with collision enabled, add platforms too of course, and get your collision working with that, even if there is no working jump function. Ideally, you'd be able to start the player on top of a platform, and make sure they can walk left and right and drop down to the floor.

Now, i have a sprite, let's call it spriteA, which gives a 1 when SpriteB is ontop of it, so far so good. But i made an array to copy the block multiply times and lay it, via:



What is the new sprite called? GetSpriteCollision(spritA, ???) I've tried everything lol

You need to drop the sprite ID into your array:

Then you can check for collisions by looping through the array:


Also I wouldn't load the image every time for every sprite. I would load the image near the start of the code, otherwise AppGameKit might load the same image 100s of times and crash your device.

Still can't get this to work. Starting to get frustrated with AppGameKit Tbh. I wish there were more tutorials out there.
