A spider hack allows players to climb up any wall like a spider.
Start by creating a new file in your code editor. Save it to a folder on your device, ensuring that the file extension is .js.
The spider hack has a lot of similarities to the step hack, so lets copy the step hack and rename the stepHackUpdateCode function to spiderHackUpdateCode:
ModAPI.require("player");
function spiderHackUpdateCode() {
//We will add code here.
}
ModAPI.addEventListener("update", spiderHackUpdateCode);
Most spider hacks work by checking if the player is walking into a wall, and then setting their vertical velocity to a constant amount (usually 0.2, for parity with ladders).
Let’s start by checking if the player is walking into a wall, by adding an if statement inside the spiderHackUpdateCode function:
if (ModAPI.player.isCollidedHorizontally) {
}
Now, let’s set the player’s vertical velocity:
if (ModAPI.player.isCollidedHorizontally) {
ModAPI.player.motionY = 0.2; //Feel free to change this value to something bigger, smaller or even negative.
}
Time to see the final code:
ModAPI.require("player");
function spiderHackUpdateCode() {
if (ModAPI.player.isCollidedHorizontally) {
ModAPI.player.motionY = 0.2; //Feel free to change this value to something bigger, smaller or even negative.
}
}
ModAPI.addEventListener("update", spiderHackUpdateCode);
