Hi, I’ve found an amazing 3d particle explosion, with a depth perspective. But it was created in AS1. When I tried to put it in AS2 I have an error message because the syntax is not compatible.

Here’s the error message:

Math.toDegrees = function (theta) {

Symbol=path–fragment, layer=actions, frame=1, Line 12: There is no method with the name ‘cosd’.  
initVelZ = iSpeed \* Math.cosd(iPhi);

Here’s a part of the code:  
Math.toDegrees = function (theta) {  
return theta \* 180 / Math.PI;  
}

Math.toRadians = function (theta) {  
return theta \* Math.PI / 180;  
}

Math.cosd = function (theta) {  
return Math.cos(Math.toRadians(theta));  
}

Math.sind = function (theta) {  
return Math.sin(Math.toRadians(theta));  
}

Does someone have any clue how to fix it? :hugegrin:

Thanks
