![Homing Rocket in 2 lines [Game Maker | Basics] @1upIndie](https://i.ytimg.com/vi/guKiHqvvpxY/maxresdefault.jpg)
Uploaded August 2023 | Updated September 2026, 7 hours ago
This basics video tutorial shows you how homing can work in GameMaker Studio with 2 lines of code. There will be a follow up video on a homing rocket barrage like you see in games like Armored Core, but the cheap man's 2D version.
I got the inspiration from Ellaris who is a discord member, so thanks for the idea buddy! The 2 lines are very easy to do and work more or less but are a building block to advance this concept.
First we need to create the rocket and give it an inital speed, direction and angle to start of with and gradually change the flying direction.
So what are those 2 lines? Well, we add constantly in the step event of each rocket to it a value that gradually ("delayed") turns towards it's target position. For that we need the current direction of the rocket and the perfect direction from the rocket to the target (which we get by the rocket's x,y and the targets x,y and get it by point direction). Then we get the resulting angle difference and use sign to clamp the result to 0,1,-1. That added to the current direction turns the rocket towards the the target, but we can use a fixed value to increase/decrease the turning around speed to our liking. Then we set the new direction to the image angle so that visuall it looks sound aswell. That's it!
The code if found as usual in the comment section.
🚧 For the future: There will be follow up video that shows how to visually advance this core setup to an homing missile barrage

This is the 11th and final video in a series on remaking Vampire Survivors in GameMaker.
The first part of this video tutorial shows you how to make a xp system that makes scale upwards. Before we can make a menue popup system possible we need to block things to like spawing, player movement, enemy redirecting. That we do by a simple check if the an obj_upgrade is present in the room. This object is being spawed if we have a level up and goes away if one of 3 choises is being selected. So we block coin collecting, the spawning of new weapons, player input (to move while an upgrade is happening) and the enemy control loop is being overritten so that the enemies dont animate and move towards the player. Thats it!
🚧 For the future: This series will will build expanded the further we go into the series. This series has ended offically with this video. The current project and an upgrade version will be added to my patreons and itch.io buyers.

This basics video tutorial shows you how to use sprites as a font in GameMaker.
The idea is quite easy. You have a cool looking font but it is an image. To use the is as a normal font you need to a few things. 1st you need to import it into GameMaker and slice it up as single images (control + I) 2nd you need to tell GameMaker with font_add_sprite_ext that you want to use this sprite as a font and give GameMaker the instructions what each character means (represents). Here you have a string (mapstring) with all the characters you use sprite as sprite and the corresponding character that it is representing. 3rd you need to store the newly created font (asset) into a variable and set with draw_set_font this spritefont to be used. Thats it!
Trivia: GameMaker once your export/run your game takes your used normal fonts and converts them into glyphs (images), which is the same as the sprite font and you can see both in the texture page.
Tldr:
1. import sprite font,
2. set a mindmap string what each image means
3. store and set it to be used

This enemy ai tutorial shows you how to make an enemy that bounces off walls (ricochet) with only 3 lines of code in GameMaker Studio.
The idea is quite simple. You give you enemy a start speed plus a direction where to go to. Movement is now setup, the automatic bouncing work when you have a collision with an instance wall which needs to be flagged as solid. To automatically change the enemys direction just input move_bounce_solid and viola, it does now bounce off walls
This system can be used for bullets that reflect, bounce of walls also.

This video shows you the basic theory behind making a Steam capsule art image and what kind of trends are visible so that you can use these informations on your own games capsule art.
If you have been wondering what you can do to get more attention towards you game with your capsule art or why should be actually in there and as well as you are curious what kind of trends of the topseller are being set as standards, well then this video is for you. The second part (learn from the top seller what works and see trends) is a follow up video because it was too long and rambly.
If you just want the quick and dirty tldr info, here it is:
1. First establish some basic rules to follow:
- few elements, less is more
- focus points/high lighted things/visual hooks (via color/art)
- hierachy of elements (top left to right)
- style/color consistency
- balance/symmetry
3. Trends
- no pixel art
- dark themes, dark colors, male audience focus
- emphasis on a head/action/prop
- household names can get away with all
- text is mostly white/golden/orange/brown black
- no idea on your own capsule? Open skys and fog and text
- no gore/no sexual stuff

This basics video tutorial shows you how to access data from structures like ds_list, ds_grid, ds_map or arrays in GameMaker.
The idea is quite simple. You create your own data like a ds list or an array and want to access/read out the value stored in there. Accessors are a shorter way to do that with a specific letter for each data structure. So if you want to access a specifc index of an array you can use the @ letter or for example for the ds_list the | letter. Thats it!

This vfx tutorial shows you how to make the fog effect like in Dead Cells with a few mouse clicks in GameMaker.
Before the newest patch 2022.8 you could also create this effect with particles which is a bit more difficult and resource intensive then now. We now can use the newest visual effect: Fractual noise, which overlays the area/screen with a fog like texture to enhances the graphics of you game. You simply create a black colored sprite, give it a transparent opacity and place it on an asset layer. Then you assign this asset layer the fractual noise effect. Play around with the opacity and the values in the inspector until you get the result desired. Thats it!

This basics video tutorial shows you how to depth sort (depth system) in GameMaker.
Things feel natural if they are being draw correctly. Image a stack of cards and it is obvious that the top card would be visible to you. So what we do is to check where the instances are and sort them to their own depth (or their own layer so to say) according to their y position in the room. We cluster all the instances into a parent object and swap their current depth to their -y value. We do that with the with statement that allows use to go through all the instances and swap their own depth. Thats it!

This is the 7th video in a series on remaking Vampire Survivors in GameMaker.
The video tutorial shows you how to use the weapons created to damage the enemies and if their hp pool is zero to destroy them. For that we first assign a damage value to the weapon parent and assign a hp variable in the enemy parent which is getting substracted later on. So we need to create a collision rectangle list (or any other collision you prefer) to get the id of the enemy being hit/collided with and there we substract from each enemy hit the hp the damage value. If the hp is zero or below we remove the enemy instance from the game. Thats it!
To refine this system, we organize the damage values of each weapon in the player and each time we spawn a weapon we grab the current value, which will increase/change during gameplay. Normally you would do that in an outside controller object, but this simplified version does the trick also. Also note that we use a collision [rectangle] list because this is making sure we get each step all the instances getting hit by the weapon. The regular collisions only collide with one instance each step which would result in instance visibly hit not getting any kind of damage or hp reduction.
🚧 For the future: This series will will build expanded the further we go into the series.
