15-MiniGolf App Inventor Tutorial

[@paulabauer4337]

this video is goated because of you I got a A for my test and my teacher was very impressed. my skills that I showed were so good

[@timothyurness]

Note that in the newest version of App Inventor, the "clock" object can now be found in the Sensors drawer.

[@studentsin3labs776]

yep

[@connersnyder2031]

This app can be expanded so much!

[@laceyhale6942]

How did you get the "7" into the math block??? I double-clicked the "return" key on my keyboard to get a blank to put the number in, but how do I get it to the blue block??? Couldn't really tell in the video. You did it really quick.

[@timothyurness]

In the blocks editor/viewer, make sure you click on the (white) background to ensure that nothing else has the focus. Then type in any number and press return -- the number in a blue "math" block should appear. If this doesn't work, you can always manually get a blue block by clicking on the "Math" block on the left hand side (under the built-in menu).

[@laceyhale6942]

Got it! Thanks so much.

How do I make my own obstacles?

[@kevcarey3]

Thanks for the video. When my ball bounces off the obstacle, it reverses its x direction heading. Therefore it is ineffective for bouncing off the side of the obstacle. Is there any simple way to remedy this?

[@timothyurness]

This is an excellent question. Unfortunately, there is no simple remedy. One alternative, however, would be to create an obstacle that consists of multiple image sprites, and have the .collidedWith block update the GolfBall heading as appropriate. For example, if the ball collides with the obstacle in the x direction, the GolfBall heading should be updated to 180 - GolfBall.Heading. See the following screen shots for a push in the right direction. analytics.drake.edu/~urness/appcamp/blocks.png analytics.drake.edu/~urness/appcamp/blocks2.png analytics.drake.edu/~urness/appcamp/obstacle2.png

@@timothyurnessreally??

[@hylife808]

Thank you very much for this tutorial as it is very clear to understand you. However how do I get the reset button to work? I am a baby developer, nowhere near a junior developer so watching videos like yours actually gives me a visual learning hands on experience type of thing. Please help on the reset button. Or anyone. I would like the ball to disappear in the hole then re appear somewhere random on the screen. Thank You

[@timothyurness]

+K. Kahokuokekai You'll need to use the "when ResetButton.click block". I think this might help: analytics.drake.edu/~urness/appcamp/reset_button.png

[@silblossom]

Hi... excuse me how do u make it stop at 18 holes???

[@zainababdulsalammahmoud8278]

How do you get that obstacle?

[@weallgames4289]

thank you so much that was really helpful thank you

[@harryroden1788]

thankyou so much computer studies assignment done !

[@רננההילל]

How do you have the blue rectangle?

[@iddubdragon7768]

you must charge the image from your pc and after in prpieties you choose the image man

[@daniellechan5980]

If you do the reset button "when reset click"- 'do set golfbal x and y to..." On what number do you put it?

[@timothyurness7581]

It can be reset to where ever you would would like. I would suggest starting with x=50 and y = 290. Adjust as you see fit.

[@dodazoza367]

you have forgot about the reset button

[@bags534]

When the ball hits the Obstacle from the sides it doesnt bounce.

[@timothyurness]

+BRKcbx Make sure you've implemented the "when Obstacle.CollidedWith" block. Take a look at 7:49 in the video.

[@목도리도마뱀-l4b]

I am trying to follow you but there is a problem. I just can't open the PNG

[@chrislordnine]

can‘t get dem resources, where can I find them elsewhere? Edit: nvm, found them

[@jainamlakhtaria9788]

Why dont we set the Z component of the obstacle as same as the ball's i.e. Z=2.0 ?

[@timothyurness]

The Z component is used to determine how elements should be layered relative to other objects. It is not used in collision detection. (ai2.appinventor.mit.edu/reference/components/animation.html)

[@frantisekvanco5951]

my ball didn t bounce from an obstacle, what can I do when it is not working ?

[@frantisekvanco5951]

ok I passed it. But sometimes a ball go thrught the obstacle (from the sides of obstacle, from left or right) What now?

[@erdenebulagbuyanbat1735]

next video? where is

[@hilmialjarumi6769]

where the reset button?

[@timothyurness]

Go to the ResetButton drawer and pull out the 'When ResetButton.Click' block. The interior of the reset button code will look very similar to the blocks inside the GolfBall.CollidedWith block at the end of the video. You'll just need to change the numbers for GolfBall.x and GolfBall.y so the position of the ball is changed to where you want it to be reset.

HOW TO SET UP THE ｒｅｓｅｔ button ? dont work

[@davidwilliamchristopher5467]

Hello Timothy! Thanks so much for sharing this tutorial, your directions are very clear to understand! I do belive you forgot to program the RESET button to do what its suppose to do. Can you please make a video on," How to Swipe left/right and top/bottom to trigger something?"" The print version is here:- puravidaapps.com/snippets.php#2flung I am completely stuck on this one. I want to be able to swipe right or swipe left for the photos to show up. also how can you make a youtube video play inside the app? Thanks so much, any help will be greatly appreciated! David

[@cheungchingchan1799]

Why the reset button doesn't work

[@rubylee9989]

You forgot to specify about the reset button

[@timothyurness]

Thanks for the note, Ruby. The interior of the reset button code will look very similar to the blocks inside the GolfBall.CollidedWith block at the end of the video. You'll just need to change the numbers for GolfBall.x and GolfBall.y so the position of the ball is changed to where you want it to be reset.

[@rubylee9989]

Thanks!

[@leorobets8054]

thanks a heap

[@ericco7804]

FAKEEEEEEEEEEEEEE!!!!!!!!!!!!

[@mohamito]

Not a very good tutorial. This is really only good for the designer part of the game, the blocks and game its self is incomplete and very empty. Would not recommend using this video to help you make a mini golf app.
