Never ever imagine the effort being put behind making a game, yet we all love to play and try different games; but the science behind it is surely not a piece of cake for all, thanks for this another amazing understandable tutorial 👌

As kid i loved to play this game. so happy to see that now i can try making it as well

[@lifeisthrillingyt7991]

These all technalities of programming have become simple after learning so much from your channel.

this is really interesting tutorial and easily understandable for those who are struggling and making space invader game in MIT App inventor

[@adyamy4052]

U r an amazing teacher. My son watches all ur videos. Thnx for sharing

[@uzmashahzad9061]

Space invader game development is exciting. Your coding tutorials are really very productive to learn all procedure systematically for any beginner.

[@shaimaraja6371]

it was one of my fav games in my childhood.... :) thanks to you and your well structured tutorials, now I know how to develop this game myself ;)

[@mediatrends4171]

space invader game development is really interesting as u are sharing complete app development series and your tutorials are very well explained

[@ummehaadikhan8965]

Found such a helpful session , the whole demo is step by step easy to go through

please help i am getting error 703 so its not playing the explosion sound

[@ObsidianSoftEducation]

Try using some other mp3 file

[@keleqz3239]

Whenever I try to connect my pc to phone to play on the smaller device, I always gets a notification saying "Error from Companion: error: unrecognized method. (irritants: setMarkOrigin)" and I'm not sure how to fix it

[@ObsidianSoftEducation]

Please update your companion app.

[@uzmaworld3613]

Very gud video for kids now a days kids are always spend time on mobile games but when they learn making games its very gud for them

[@humairasiddiqui8476]

wow wonderful sharing you are amazing your all videos are superp

[@zimalamal8200]

My kids will love to give this one a try

[@ayyanadam3889]

I like the way you explain We learned many things from this video

[@miao3927]

helppp it says that theres an error it says runtimeError. Irritants: (the operation + cannot accept the arguments: , [“score:”],[1] Bad arguments to +)

[@ObsidianSoftEducation]

How are you adding a one to your score? Is score a global variable?

[@sanaimran1786]

nice tutorial as always

[@ObsidianSoftEducation]

Thanks 😊

[@niconii16]

When I shoot the bullet in my rocket they are not colliding to each other. When I try to shoot the bullet goes in left or right side. I watched your vid many times if ever I missed a code but it's all the same. How to fix this?

[@ObsidianSoftEducation]

Have a look again at your rocket.touched event. When the rocket is touched, we first move the bullet to be on top of the rocket. If your bulllet is on the left or right-hand side of the rocket, then there might be an issue with the bullet.moveTo code. The x position of the moveTo should be rocket.x+(rocket.width/2) so confirm that your code's logic is the same.

[@atikamujtaba]

Very informative video and very well explained!

[@saturnsbrain4210]

How can I make an alien ship that moves down and when it reaches the spaceship, it is destroyed?

[@ObsidianSoftEducation]

The code of the alienship coming down will be similar to the bullet code. But speed will be slower and direction will be opposite. When it reaches edge, just destroy it like we destroy the rocket ship

[@HokProject-q4h]

Why is mine the space ship isnt spawning when I first killed it and it also said the operation + cannot accept the arguments: , ["SCORE"], [1] Note: You will not see another error reported for 5 seconds. pls reply this hour.

[@ObsidianSoftEducation]

Please watch video carefully. You might have missed something. You can also compare code with written tutorial. Link is in video description.

[@ANDRADEPatrickMiguel-jv8hu]

Hi! How can I make the alienship double and the laser double as well?

[@ObsidianSoftEducation]

I don't know what you mean by doubling the bullet. To make a second alien ship, add another image sprite for the second alien ship with the same properties in the designer view. Add all code for the alien ship 2 just like the original alien ship and in the bullet collided event, use a logic OR block to check if the bullet collides with any of the alien ships.

[@munizasaqib]

Explained very well

[@maryamkitchn1837]

U explain really well thanku for explain

[@Sana-cx6ms]

nice tutorial 👌

[@mujtabakhan00]

Very informative 👍

[@katheryn1458]

my alienship or saucer doesn’t reappear after the rocketship has destroyed it

[@ObsidianSoftEducation]

First of all, check whether you have enabled the clock sensor's timer in the collidedWith event as the code for making the saucer visible is inside the clock's timer event. Verify that in your clock's timer event, you are giving a random number to saucer.X between 0 and (Canvas.width-saucer.width) . These could be some of the reasons why the saucer is not reappearing. I have also shared my aia file and given a written tutorial too so you can do code comparison with one of these. obsidiansofteducation.blogspot.com/p/space-invader-game.html

[@brandslover1358]

i was pro in this game, thanks for reminding me this game 😍

[@Yuaneki]

My alienship It doesn't move left and right automatically why please help

[@ObsidianSoftEducation]

It is in the clock's timer code. Please verify that you have given alienship.x a random value between 0 and width of canvas. Also, the alienship will spawn again only if you have destroyed it. It doesn't just move left and right. It appears in a random x position after being destroyed. The y position of alien ship stays the same.

[@Yuaneki]

@@ObsidianSoftEducation Yes, I wrote this code according to what you did in the video, but it still does not move to the left and right

[@ObsidianSoftEducation]

Does the alienship appear in the same place as it was destroyed?

[@ummemuhammadabdullah1428]

Very good opportunity to understand how coding works for kids to creat their own fav games

Kindly explain more about your problem. You have to go to the blocks section to see the code.

Part two???

This is a full tutorial video for making the space invader game. There is no part 2.

[@sammislearning]

Very informative

[@footballgaming7479]

Is there a way to make it so you lose?

[@ObsidianSoftEducation]

Sure 😊. You can have an alien ship that moves down and on touching the rocket ship, should destroy the rocket ship.

[@iqrazubair4482]

Nice information

[@carestudio1303]

It very good activity for kids apart of spending time on useless gaming, create your own and play 😊
