How to Make a Spaceship in Roblox for Your Game

Run "Roblox" and select "Ultimate Build" for the game mode.

Drag two 10-by-10-by-1 platform bricks from the brick platforms scattered across the level onto the ground. Stack them on top of each other.

Drag four five-length girder bricks onto the 10-by-10-by-1 platform and place each one on the corners of the platform vertically.

Repeat steps 2 and 3 to make the rocket ship as tall as you like. If the rocket ship grows taller than six stories, however, it will become increasingly unstable and is likely to crash.

Drag four five-length girders from the block spawning stages and place them horizontally around the 10-by-10-by-1 base.

Drag two gray thrusters onto the horizontal girders, placing one thruster on each end of the girder. Repeat this for each horizontal girder so that there are eight thrusters total. These gray thrusters are the game's strongest thrusters and will provide all upward thrust.

Drag eight yellow thrusters onto the horizontal girders, placing two on each girder. Mount these thrusters on the outermost sides of the horizontal girders and orient them so that they all face the same direction: clockwise or counterclockwise. These thrusters will cause the spaceship to spin, which is necessary to maintain balance.

Drag eight triangular blocks onto the top of the rocket ship to create a four-sided pyramid at the top of the ship.

Drag a seat block into the exact center of the spaceship on any level. The seat does not have to be on the inside of the ship; you could place it on the tip of the rocket ship.

Click on the seat to enter the spaceship.

Click on one of the thrusters to activate the rocket ship and launch the vehicle into space.
