[@AmallahGaming]

Thanks for the tutorials! I had to rewind a fair bit for this one and your sound effects one because I had trouble keeping up, but I feel that's only because it's my second day working in GameMaker. But rewinding helped me a lot anyway as I started understanding different concepts better hearing them repeated again.

[@GameMakerEngine]

Glad it's working for you :). Have you worked in any other game engines before? We have a blog to help people get started if the are coming from Unity: gamemaker.io/en/tutorials/moving-from-unity-to-gamemaker

[@AmallahGaming]

@@GameMakerEngine I'm just a QA in a studio that currently uses Unity, so I've never used it before myself, I just wanted to toy around with things and see what I could make. I used GameMaker for a class back in high school (2012ish) and it's a LOT different now than it was back then. Not in a bad way of course, I was pretty pleased seeing all the changes and improvements. Next I'll be trying out the Hero's Trail tutorial and try to customize it a lot more than I did with this one. Keep up the good work!

This is the final video we have in this tutorial series. If you go on GM's channel page you can see 2 playlists with stand-a-lone tutorials you can adapt them to add onto this game. Then there are also interviews with Game Devs about how they made their game, life coaching sessions and stuff like that :). kzbin.info/door/OvndqCF3iN2SksQDwR95wg

Thanks for the tutorials. and the link did not work but it more fun to make one. so it make it fun

[@cliffbowman6816]

"Teleport" ship to a random location would be a common and fairly simple powerup to add - but how could one code a "teleport to safe location" to prevent the ship from coming out of hyperspace either in a rock or surrounded by rocks that will destroy it instantly? Another good powerup is a shield - drawing a circle around the player ship and "bouncing" off of rocks instead of passing through them or exploding. Need to take into account a situation where rocks surround player ship so there is nowhere to bounce TO - bounce rocks away from player instead/as well? It'd be interesting to see a shader being used to add "glow" to all the non-text elements in the game room, but that might be a bit beyond the scope of this particular tutorial series, BTW, loving the new "Space Rocks" tutorials - the first one simply blew me away with how little effort is required to produce an actually playable foundation for a game.

[@cliffbowman6816]

Come to think of it I would probably have an obj_teleport with an oversized sprite and collision mask. Never draw the sprite, but this object would be spawned at a random location when the user uses the teleport power up. On creation it would check for collisions and relocate if there is one, until there is no collision - then recreate the ship/player object there and destroy the obj_teleport object

[@schl4u]

I know this is an old comment but in case anyone is wondering: You can use the place_meeting() function to check if the space is safe before teleporting your spaceship.

[@64bitrobot]

my favorite part of this tutorial was the confirmation of the existance of delta_time.

[@deathincarnatesplace]

Add a thrust to it for the ship but using rings like it is magnetic. also i don't remember engine sounds but asteroids has one.

[@Zenith2863]

i'd like to see a powerup that puts a shield around the ship, protecting it from a hit from an asteroid, if you make another one of these. maybe a lives system as well? i think another neat small touch would be to add a little engine flame sprite and/or sound effect to the ship when you're moving forward. i'm a beginner so i don't really know, but for the shield, i guess you'd create a sprite, and make it so that when the powerup variable is 3, it would create an instance of the shield around the ship, on a 10 second timer. add collision on the rock so that hitting the shield destroys it (or changes its direction of movement), removes the shield, and maybe gives the ship some s so the powerup doesnt feel janky.

[@GameMakerEngine]

Sounds like a cool idea

[@DaWaffleH8ter]

Did you ever get the shield to work for this? I'm currently trying to get that made but can't get the shield object to stay with the player. Any help would be appreciated :)

[@ponjoh90]

@@DaWaffleH8ter Hi! I did this by adding this in the "Draw GUI" event for my obj_shield. You could probably just draw another sprite on top of the obj_player instead if you don't want the shield to be a separate object (but I don't know how) if (instance_number(obj_player) > 0) // this check is to see if the player is still alive since I both the ship and the shield sometimes colided with the rock, and then I died and then tried to access obj_player, if you make the player invinvible during power_up == 3 this won't be a problem. { x = obj_player.x - sprite_width / 2; y = obj_player.y - sprite_height / 2; }

[@ponjoh90]

For anyone else curious. To add a sprite on top of the player, instead of the entire object, add tis code to obj_player.Draw (not Draw GUI). You need to have a spr_shield2 sprite for it to work. if (powerup == 4) { draw_sprite(spr_shield2, -1, x, y); }

[@gearsgroundup]

@@DaWaffleH8ter I actually just implemented this. I duplicated the obj_bullet collision event that was on the obj_rock. That way it works just like the projectile bullet but now it is a scaling in size ring. I referred. to this new circle object as obj_halo. On the obj_halo I have the following: Create event: image_xscale = 1; image_yscale = 1; Step event: image_xscale += .03; image_yscale += .03; x = obj_ship.x; y = obj_ship.y;

[@speedoreo1462]

i think a powerup where the bullets loop around would be cool ,ill try adding it to see if i can!!!

I had some trouble downloading the sprites. So I used a picture of jam for spread and me doing a funny face for the invincibility sprite.

yymps is a format that GameMaker Studio accepts. In fact, it's a format that *only* GameMaker Studio accepts.

For some reason even though it seems all the code is exact it wont spawn in the power ups randomly (using gml code)

[@HazMatch3]

I am also running into this issue!

[@masterrocket31]

how do you add the second power up as an additional option in GML code? im having the same problem. Edit: did some fiddling around and got it to work. the code should look like this for having both powerups spawning from rocks in the obj_rock collusion with obj_bullet section. hope this helps. if (obj_game.powerup_time < 0) { var _obj =choose(obj_powerup_spread, obj_powerup_ghost); instance_create_layer(x, y, "Instances", _obj); obj_game.powerup_time = 20; }

[@ShootFirstNS]

​@@masterrocket31 Thanks for this

[@FanGameFishing]

I feel like I followed everything pretty well however after 10 seconds has passed or longer the power up still doesn’t appear!

[@radekaszek1048]

I had a similar problem, but in my case it looked like sometimes power ups were creating and sometimes weren't. What worked for me was cutting part of the code responsible for destroying rocks (all the if-else statement) and paste it at the end of the collision event.

[@rowgue]

@@radekaszek1048 Can confirm, this is due to the order - Using the visual code I just Cut+Pasted it at the bottom at then it worked

[@helinaojok6181]

I followed the steps so far and was able to create the game. But the power up spread doesn't want to spread, despite following the instructions. Everything else happens but no spread of bullets. Can you help me please?

[@GameMakerEngine]

Make sure the code is the same! Even better, try to understand what's happening in the code shown in the video, and read your code to see if it makes sense - to know "what IS my code doing?" and you'll figure it out. :) -Gurpreet

excelente tutorial, excelente professor, documentei todo o jogo no meu caderno e agora vou treinar

[@DecksandGames-jb1fc]

For powerup, I just get idea for spread shooting of 100 bullets or more/less. I test it with 5 and looks cool, but will be kind of same I guess, with 100 just like with 4. Just will have larger range. Maybe some kind of laser just like in Breakout game or maybe to add some lives?

[@ricky_3]

hey i want to change the colour of sprite with the use of points like after 1000 points the ship turns red or purple how to do that

[@GameMakerEngine]

Hey, in the Step event you can add a simple condition: if (obj_game.points >= 1000) { image_blend = c_red; } In GML Visual, you can use an If Variable condition to make the same comparison, and then use Set Instance Colour to change its colour.
