This enemy ai video tutorial shows you how to make an enemy that throws in an parabollic arc grenades in GameMaker Studio.
The idea is quite simple. You need to setup the grenades with a direction upwards plus set some speed. To create the arc movement you need a secondary force downwards which is gravtiy. You can optinally make the grenades bounce by setting the a wall collision with move_bounce_solid and give the grenade a bit of friction to reduce its overall speed values, so that the bounce looks realistic. That's it!

![Constructor - The king of data [GameMaker | Advanced]](https://i.ytimg.com/vi/WpXfj5hpZeI/mqdefault.jpg "Constructor - The king of data [GameMaker | Advanced]
This advanced video tutorial shows you how to use efficient data with constructors in GameMaker.
Image you have an inventory with hundreds of entries and each entry has values like name, costs, icon image etc. . Creating for each entry one variable per value even with arrays is not an good way to handle that task. So what I think is one efficient way is to create structs via constructor and store each entry into one array. By that you have only one index that defines which item you want values from. Thats it!
Tldr: Yes

![Roadmap and starter project file [#0 Remake Undertale in GameMaker ]](https://i.ytimg.com/vi/Wz625xrRQMQ/mqdefault.jpg "Roadmap and starter project file [#0 Remake Undertale in GameMaker ]
This is the 2nd video (But since it is only a preview and roadmap I started at 0) in a short series of remaking the battle system which you see in Undertale in GameMaker.
What is Undertale?
Undertale is a video game made also in GameMaker by Toby Fox where
you play as a child that is being trapped in an unknown world and your job in this linear story is to progress. The difference is that you can genocide monsters, be neutral or even befriend them. This throws the concept of enemies being simply neutral farm on its head.
// Part 0
This time I only discuss that you can download a premade starter project file containing all necessary images that are being used in this series and a basic overworld movement system so that we can start with something (also dont see the point of making a top down movement system because that is not the focus of this remake series, so it is there by default).
🚧 For the future: This series is under construction. There will is a free downloadable project file for everybody, so you can grab and do whatever you like to do with it (you can credit me, but not necessary). Also, this video series will be handled like my Hotline Miami series. If the views drop off a cliff (that I do see happening) it will be then discontinued.

This basics video tutorial shows you how to control the animation of an object/instance in GameMaker Studio.
The idea is quite simple. You want the animation to be faster or slower or even end once the animation is done. For that you need to understand how the image index of the instance in question is being controlled by the image_speed. Thats it!
If you are unsure about controls in Gamemaker, I got you covered:

This enemy ai video tutorial shows you how to make a randomly teleporting enemy that that doesnt spawn on walls in GameMaker Studio.
The idea is quite simple. You need to define at the start a radial spawn circle and save the first x,y coordinates where the instance has been placed. This area defines possible spawn locations. Now run down a timer and when that reaches zero we try to teleport the enemy in a random x,y coordinate in that possible range. Here we check multiple times if that spot is not blocked by a wall instance and if no, we set the x,y coordinate to the random new positon. Thats it!
