Game 3-Space invaders

Space Invaders

After completing both my breakout and pacman games, i started on my space invaders. Like the pacman compared to breakout, this was a little more difficult to make as i also experienced some technical difficulties, which i hadn't had experienced with pacman or breakout.

The splash screen below is one of many difficulties i had. Not the making of it but the action of it switching to the next room once you clicked the space bar- It would slightly glitch to the next room but then go right back to the splash screen so i had to delete the event to go to the next room and re-add it back which was very simple to do, however, i hadn't experienced this with my other splash screens from the previous two games.

Once i finished, tested and evaluated my game i checked to see if i had met the following requirements:

• The aliens should start at the top of the screen and gradually move down.
• The shooter object should move along the bottom of the screen and fire missiles at the aliens
• If a missile hits an alien, it should explode and disappear.
• Every time an alien is destroyed the player should gain a point and the player wins the game if a certain score is reached.
• If the aliens reach the bottom of the screen,the player loses the game.
• There should be two types of aliens and the second type cannot be destroyed until all of the first type have been destroyed.
• The game should have sound.

 As seen above, the certain event i had a problem with was that the second type would also die even before all the first type were eliminated. I had read the game maker book step-by-step but kept having the same problem. Like the last problem i had to delete ALL my events for Alien2, including the ones that were not attached to that particular event.

Once i managed to finish all the problems in hand, which only took me a few minutes as they were easy fixes i ran my game again in debug mode and found that everything was working perfectly! In conclusion, although i found some difficulties whilst making this particular game, i progressed through it and found ways to fix it and eventually got it all to work and run smoothly.

Update:
As i decided that i didn't want to keep the boring background for the space invaders game, I chose to create a more fitting background with that alone proving a perfect fit to suit the game. The background being a black and green lined background that gives it that extra effect for my game. Although it is a simple design it helps create character for that game- I also had to double check that once i created the background that the enemies/shooter and ball didn't colour mix with that background. As well as the new background, i also wanted to reskin the game so i changed the enemies from the regular ghosts to these 'slime' enemies that almost represented a slug of sorts!
